An Introduction to Mass Spectrometry LC/MS is a powerful analytical technology that offers substantial benefits. There are four basic components that make up a Mass Spectrometry instrument. Applied Biosystems/MDS SCIEX has worked at the forefront of the industry to innovate and develop the most advanced technological solutions in each of these components in order to deliver the most powerful systems available to our customers. SAMPLE INTRODUCTION I. ION SOURCE Creates charged ions II. VACUUM INTERFACE III. MASS ANALYZER Separates the ions in space or time based on their m/z ratio. IV. DETECTOR Counts the electrons generated from the ions V. DATA ANALYSIS Figure 1. Stages of the Mass Spectrometry Process In LC/MS, the sample is first separated with HPLC, and then Mass Spectrometry is used for detection. The Mass Spectrometer does this by producing charged particles (ions) from the analytes in the sample and using electric and/or magnetic fields to separate the charged particles according to their massto-charge (m/z) ratio. The resulting data are processed and analyzed by a data management system. The stages of this process are described above in Figure 1.
I. THE ION SOURCE After introduction of the sample from the HPLC system, the sample is ionized by the ion source. Types of sources include electron impact ionization (EI), chemical ionization (CI) and atmospheric pressure ionization (API). In LC/MS, the most common source is API, in which the mobile phase and sample are ionized at atmospheric pressure and the analyte ions are introduced into the mass spectrometer. There are three commonly used API methods: Electrospray Ionization (ESI) produces analyte ions in the liquid phase before they enter the Mass Spectrometer. It is used for polar small molecules, peptides, proteins, and oligonucleotides and other high molecular weight compounds. See Figure 2. Atmospheric Pressure Chemical Ionization (APCI) evaporates the sample through a heated nebulizer before ionization using plasma discharge. APCI is often used for thermally stable molecules that require more ionization energy. See Figure 3. Atmospheric Pressure Photo Ionization (APPI) is similar to APCI, except it uses photons to ionize the analyte molecules, and applies more ionization energy. This can lead to better detection limits for low-polarity compounds. See Figure 6. API Sources offered by Applied Biosystems/MDS SCIEX Electrospray Ionization (ESI) TurboIonSpray source (Figure 2), an IonSpray source with hot drying gas and flow rate from 2-1000 µl/min NanoSpray source, for improved sensitivity at lowest flow rates MicroIonSpray source, for very low flow rate up to 2 µl/min IonSpray source, a pneumatically assisted electrospray with flow rate from 2-200 µl/min Atmospheric Pressure Chemical Ionization (APCI) The Heated Nebulizer Source (Figure 3) is useful for small polar and neutral compounds. Combined Sources Combined sources offer analytical flexibility The Turbo V Source (Figure 4) has exchangeable probes for ESI and APCI The DuoSpray Source (Figure 5) allows simultaneous or sequential use of ESI and APCI.

II. THE VACUUM INTERFACE The vacuum interface ensures the transition of ions from the API source to the mass analyzer, which is kept under vacuum. Curtain Gas Interface The Curtain Gas interface protects the interface region from contamination and improves LC/MS productivity by blowing a reverse stream of nitrogen into the ion stream, creating a curtain that prevents the ions from striking the curtain plate and being neutralized.

The Turbo V Source Figure 6 PhotoSpray Source
III. THE MASS ANALYZER From the ion source, ions are transferred to the mass analyzer where they are separated according to their mass-to-charge (m/z) values. The mass analyzer operates under a vacuum to ensure that ions travel with maximum efficiency. There are several types of mass analyzers: Quadrupole Systems Quadrupole mass analyzers use four parallel electrode rods arranged in a square to generate electrical fields that filter ions based on their mass-to-charge ratio as they travel through the rods. At particular magnitudes and frequencies, only ions of selected mass reach the detector. By consistently altering the electric fields, the masses of all ions can be scanned sequentially from low mass to high mass or vice-versa to give a mass spectrum. Time-of-Flight (TOF) Analyzers TOF analyzers apply a constant electrical field to all ions and measure the time the ions fly before reaching the detector. The relation between time and m/z ratio gives the mass of the ion. The heavier the ion, the slower it travels; the lighter it is, the faster it travels. Ion Trap Systems Ion trap systems use a spherical electrode to produce an electrical field that captures ions as they enter. Trapped ions are processed in a 3-dimensional oscillating field from which they can be released selectively. These systems are known as 3-D ion traps. Applied Biosystems/MDS SCIEX created a major breakthrough by introducing Linear Ion Trap where a quadrupole is used to trap ions thereby considerably increasing the trapping capacity and hence dramatically increasing sensitivity. Tandem MS Systems Mutiple-stage or tandem MS (MS/MS), is a technique in which mass analyzers are used in series to obtain structural information or to improve quantitative results. In a hybrid system, a TOF system or a linear ion trap replaces the third quadrupole (Q3) of a triple quadrupole to form the QqTOF (quadrupole-tof) and Q TRAP system technologies. Description of the Different Scan Modes in MS/MS Operation In MS/MS operation, different scan modes can be used to get complementary information about the sample. These modes are chosen and programmed using the system software. Product Ion Scan Provides structural information and identification of fragment ions Precursor Ion Scan Determines the origin of particular product ion(s) created in the collision cell and is frequently used for drug metabolite identification Constant Neutral Loss Indicates which ions lose a neutral species equal to Q1 Q3 difference Multiple Reaction Monitoring (MRM) Used primarily for quantitation studies, this mode allows monitoring of multiple precursor-to-product ion pairs and is the best way to maximize signal/noise ratio of compounds The LINAC Collision Cell A common problem in tandem MS systems is that the residence time of the ions (fragments) in the collision cell can initiate a phenomenon in Q3 called cross-talk, when ions of the same mass for multiple reactions are present. The patented LINAC Collision Cell solves this problem by using a field gradient to accelerate the fragment ions towards Q3. This offers a number of advantages, including: Multiple component analysis Small dwell times Conformation ions No loss of sensitivity Easier method development
IV. THE DETECTOR The detector measures the abundance of electrons generated from the ions for each m/z ratio. Most MS systems use some type of electron multiplier as a detector in combination with a signal amplifier. A record of all the charges detected during a scan constitutes a mass spectrum. Applied Biosystems/MDS SCIEX LC/MS/ MS instruments are all equipped with a Pulse Counting detector. This detection mode ensures that the true ion flux is collected as raw data. In contrast, many vendors use analog-mode detectors requiring both electronic and software noise rejection. This filtering of the signal prior to storage as raw data can have a dramatic effect on the data quality making poor data look better than it actually is. Understanding the detector operation is tremendously important for evaluating and conducting high performance LC/MS quantitative analysis. V.

Applied Biosystems/MDS SCIEX Systems are Used in a Wide Variety of Applications Drug Discovery and Development Applied Biosystems/MDS SCIEX LC/MS/MS systems play a key role in drug discovery and development. Improved ionization and interface technologies together with powerful software capabilities provide pharmaceutical researchers with unprecedented performance for applications ranging from target discovery to manufacturing quality control. Automated metabolite identification and characterization ADME Studies Drug target screening Impurity profiling Pharmacokinetic studies Metabolomics Tissue imaging Drug Development Quantitative Analysis of Buspirone Metabolites using LC/MS/MS Early assessment of drug metabolism of in vitro and in vivo samples requires sufficient sensitivity and specificity to measure nanogram levels of metabolites in complex matrices. The API 5000 LC/MS/MS system gives you unequalled accuracy and precision for quantitative analysis of small molecules. It also offers linearity over a wide dynamic range and exceptional sensitivity for routine quantitation of low abundance compounds in complex matrices. Drug Discovery Determination of Phase I Metabolites of Glyburide Using the 4000 Q TRAP System, A Hybrid Triple Quadrupole/Linear Ion Trap Mass Spectrometer A common strategy for metabolite MS analysis consists of using a triple quadrupole precursor and neutral loss analysis in conjunction with an ion trap single MS 1 survey with MS 2 and MSn dependent scans. Triple quadrupole scan modes provide a very selective method for the identification of structurally similar metabolites, even in the presence of strong co-eluting signals. The superior sensitivity of 4000 Q TRAP System makes it possible to detect ultra-low level metabolites, and a large number of unique metabolites can be found using the system s various scan modes. This combination provides a comprehensive view of the metabolites of glyburide. 367.1 168.8 x 100.0 393.1 2300 385.0 286.0 369.0 269.3 115.9 411.1 227.9 508.0 302.2 142.0 526.3 199.1 490.2 312.0 402.8 464.2 154.9 276.1 341.4 569.9 119.9 424.2 100 150 200 250 300 350 400 450 500 550 600 m/z, amu cps 20 22 24 26 28 30 32 Time, min 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 Time, min Excellent linearity over a wide dynamic range is illustrated in this calibration curve of eight replicate injections at each concentration of buspirone.

Metabolomics Studies Metabolomics Analysis of Rat Urine Before and After Administration of Vinpocetine In this study, MarkerView Software is used in the analysis of the effects of vinpocetine, a compound derived from vincamine, a constituent found in the leaves of common Periwinkle plant, Vinca minor L. Vinpocetine is believed to improve cerebral metabolism (glucose and oxygen uptake), increase ATP concentration, and selectively increase blood flow to the brain. After dosing rats with Vinpocetine, urine samples were collected at several different time points, monitoring the alteration in endogenous as well as xenobiotic metabolites as a result of drug administration. Metabolite Identification Identification of Propranolol Metabolites from Human Urine Samples Using the QSTAR Elite System In a drug metabolism research study, the goal is to identify all of the metabolites, both major and minor. This can be a challenging task on an LC time-scale, especially because the ions of interest may not be the most intense ions in the mass spectrum. Automated LC/MS/MS workflows using Information Dependent Acquisition (IDA) provide the framework for deriving maximum information from every LC experiment. The IDA functionality lets you focus on specific ions of interest for increased productivity. Several tools are available to narrow the search, but significant improvements have been made with the implementation of Dynamic Background Subtraction (DBS) and Mass Defect triggered IDA Software (MDt IDA Software) on the QSTAR Elite system. To highlight the power of this combination, the QSTAR Elite system was used to identify the metabolites of propanolol from human urine samples. Experiments were run to compare the number of metabolites found using a standard IDA run (dynamic exclusion) versus a combination of Dynamic Background Subtraction (DBS) and MDt IDA Software features, as compared to the expected metabolites based on the literature. Standard IDA w/ DBS w/ DBS & MDt IDA # of ions selected 912 496 288 # of Metabolites ID d 10 27 27 Results of PCA analysis on the positive electrospray Vinpocetine data. Comparison of automated data collection for metabolites of propranolol. The combination of DBS and MDt IDA significantly improves the overall efficiency of automated workflows. By greatly narrowing the search higher quality, more relevant data is collected yielding improved metabolite coverage and additional time for more experiments.
Clinical Research Applied Biosystems/MDS SCIEX LC/MS/MS systems offer analytical power, proven applications, and ease-of-use for clinical research. Therapeutic Drug Efficacy Inborn Errors of Metabolism Endocrinology Research Biomarkers Toxicology Forensics and Toxicology Applied Biosystems/MDS SCIEX LC/MS/MS systems offer unparalleled performance for identifying analytes in complex samples. Provides the maximum amount Impurity profiling of information from one LC run, Enables structural confirmation both qualitative and quantitative of drug compounds with General unknown/targeted compound libraries screening for xenobiotics in Doping analysis blood, urine and saliva samples Clinical Research A Simple and Rapid LC/MS/MS Method for the Simultaneous Determination of 4 Immunosuppressant Drugs Liquid chromatography in combination with tandem mass spectrometry has the potential for the simultaneous determination of Cyclosporin A, Tacrolimus, Sirolimus, and Everolimus with greater specificity, lower detection limits, and a broader dynamic range than commercial immunoassays. The LC/MS/MS method allows the effective removal of high-molecular compounds, important for the long-term robustness of the method, as well as minimal sample handling and rapid sample turn-around time. The concentration and identification of these immunosuppressant drugs in research studies can thus be accomplished quickly and simply, with minimal manual sample clean-up and without compromising assay precision and accuracy. Forensic Toxicology Simultaneous Qualitative and Quantitative LC/MS/MS Analysis of Opiates in Biological Matrices Although ELISA and immunoassays are sensitive techniques for detecting opiates, there is a high degree of false-positive results due to cross-reactivities among related opiates. Identification of these illicit drugs for forensic, clinical or drug-testing applications requires a specific and sensitive method. LC/MS/MS offers a simultaneous qualitative and quantitative method for analyzing opiates in biological matrices. With the advent of the hybrid quadrupole/ion trap Q TRAP System, LC/MS/MS techniques can reliably detect these compounds without any additional sample preparation or instrument time.

Food and Environmental Applied Biosystems/MDS SCIEX LC/MS/MS systems enable laboratories to characterize and monitor a wide range of compounds simultaneously, with minimal sample clean up and fast analysis times. Multi-target compound analysis Residue/contaminant screening Unknown screening and confirmation Qualitative and quantitative analysis of a wide variety of compound classes including: - Antibiotics - Mycotoxins - Beta Agonists - Acrylamide - Pesticides Food Environmental Detection of Nitrofurane Metabolites in Food with LC/MS/MS Furazolidone, furaltadone, nitrofurazone and nitrofurantoine belong to the group of nitrofuranes once used as antibiotics for treatment of gastrointestinal infections in cattle and poultry. Due to their proven mutagenic and carcinigenic effect, nitrofuranes (except for furazolidone) were prohibited in 1993 in the European Union. Despite their low molecular weight, the derivatized metabolites can be quantitated over several orders of magnitude with high accuracy using methods developed on Applied Biosystems/MDS SCIEX triple quadrupole LC/MS/MS systems. Simultaneous Quantitative Screening and Qualitative Confirmation of 300 Pesticides Using the 3200 Q TRAP LC/MS/MS System Contamination of natural waters with pesticides from agriculture is a problem of primary concern. Many pesticides which are difficult or impossible to analyze by GC/MS can be identified and quantified by LC/MS/MS after simple solvent extraction and fast cleanup. The 3200 Q TRAP System uses the acquisition time mainly for fast screening of as many target compounds as possible. Automatic confirmatory measurements are then only carried out when a pesticide is detected. The confirmatory measurement provides full collision induced mass spectra, which can be searched against a mass spectral library of pesticides.
