1 Designed for leading researchers working at the limits of conventional mass spectrometry capabilities who need to further characterize and define their samples the Waters SYNAPT High Definition MS (HDMS ) System offers unique, enabling functionality. Utilizing Waters patented Triwave technology, the SYNAPT HDMS System combines high-efficiency, ion-mobility based measurements and separations with high-performance quadrupole, time-of-flight (TOF) mass spectrometry. The SYNAPT HDMS System enables researchers to analyze samples that are differentiated by size, shape and charge as well as mass to deliver increased specificity and sample definition beyond that achievable by conventional mass spectrometers. PERFORMANCE SPECIFICATIONS LOCKMASS REFERENCE SPRAY T-WAVE ION GUIDE DRE LENS PUSHER DETECTOR QUADRUPOLE The SYNAPT HDMS System can operate in two modes: ANALYTE SPRAY TRAP ION MOBILITY SEPARATION TRANSFER (a) TOF mode (b) Mobility-TOF mode TOF Mass Resolution in Positive Ion 1 2 OIL-FREE AIR-COOLED TURBOMOLECULAR PUMPS SCROLL PUMP 5 10,000 measured on the (M + 6H) 6+ isotope cluster from bovine insulin (m/z 956) (b) W Mode 17,500 measured on the (M + 6H) 6+ isotope cluster from bovine insulin (m/z 956) TOF Mass Resolution in Negative Ion 10,000 measured on the (M - 4H) 4- isotope cluster from bovine insulin (m/z 1431) (b) W Mode 17,500 measured on the (M - 4H) 4- isotope cluster from bovine insulin (m/z 1431) Positive Ion MS Sensitivity The peak at m/z 556 from a solution of 50 pg/μl leucine enkephalin in 50/50 acetonitrile/water + 0.1% formic acid, infused at a flow rate of 5 μl/min, will have an intensity of greater than 1,700 counts per second. The instrument will be tuned to 10,000 resolution (as demonstrated on bovine insulin) and the mass range will be set to 1,000 Da. (b) EDC The peak at m/z 556 from a solution of 10 pg/μl leucine enkephalin in 50/50 acetonitrile/water + 0.1% formic acid, infused at a flow rate of 5 μl/min, will have an intensity of greater than 2,000 counts per second. The instrument will be tuned to 10,000 resolution (as demonstrated on bovine insulin), with sensitivity set to a maximum at 556 Da. Negative Ion MS Sensitivity The peak at m/z 503 from a solution of 500 pg/μl raffinose in 70/30 acetonitrile/water (no additives), infused at a flow rate of 5 μl/min, will have an intensity of greater than 1,800 counts per second. The instrument will be tuned to 10,000 resolution (as demonstrated on bovine insulin), and the mass range will be set to 1,000 Da.

2 Positive Ion MS/MS Sensitivity Using a [Glu] -Fibrinopeptide B solution of 100 fmol/μl, at a flow rate of 5μL/min and with the instrument tuned for 10,000 resolution (as demonstrated on bovine insulin), the intensity of the most intense y sequence ion from the MS/MS spectrum of the doubly charged precursor ion (785.8 Da) will be greater than 130 counts per second. This will correspond to a signal to noise ratio of greater than 50:1 (after a 3x9 smooth) on the most intense y sequence ion, for a 1 second scan. The instrument mass range will be set to 2,000 Da. Negative Ion MS/MS Sensitivity Using a solution of 500 pg/μl raffinose in 70/30 acetonitrile/water, at a flow rate of 5 μl/min and with the instrument tuned for 10,000 resolution (as demonstrated on bovine insulin), the intensity of the fragment ion at Da in the MS/MS spectrum of the precursor ion at Da will be greater than 130 counts per second. The instrument mass range will be set to 1,000 Da. Mass Scale Calibration Accuracy The mass measurement accuracy of the instrument in V-mode, using an internal lockmass, is such that the RMS error between the measured and the accepted masses of peaks which have sufficient intensity, and are free from interference from other masses, will be less than 2 ppm over the range Da. Mass Measurement Accuracy The mass measurement accuracy of the instrument, in W-mode, will be better than 2 ppm RMS, based on 10 consecutive repeat measurements of the [M + Na] + ion of raffinose (m/z ), using the [M + H] + ion of leucine enkephalin ( ) as the LockSpray lockmass. Analyte and lockmass peaks must have sufficient intensity and be free of interference from other masses. Mass Range The TOF mass range is ,000 Da in V-mode, and 20 26,500 Da in W-mode. The quadrupole mass range in non-resolving mode is 20 16,000 Da for a 4,000 Da quadrupole, and 20 32,000 Da for an 8,000 Da quadrupole.

3 Acquisition Rate Spectra can be acquired at a rate of 10 scans per second, except in pdre mode, when the maximum rate is 5 scans per second. Conditions: inter-scan time 20 ms, centroid or continuum, mass range 100 1,000 Da, single spray source. The sensitivity at 10 scans per second should be greater than 80% of the sensitivity at 1 scan per second. Dynamic Range The dynamic range, defined as the range of peak intensities that will give better than 3 ppm accurate mass (95% confidence) for 10 seconds of data, is at least 4 orders of magnitude, when measured on the m/z peak from leucine enkephalin. Isotope Ratios In the molecular ion isotope cluster of leucine enkephalin, the [M+H+1] + isotope will have an intensity of 33.8 (±1.0)%, the [M+H+2] + isotope will have an intensity of 6.9 (±1.0) %, and the [M+H+3] + isotope will have an intensity of 1.1 (±1.0) %, all measured with respect to the intensity of the [M+H] + isotope at Da. The peaks must be free of interference from other masses. Peak intensities must be below the DDTC (Digital Dead Time Correction) limit. High Mass Precursor Selection Applicable to instruments with 8,000 Da quadrupole only. The low energy MS/MS spectrum of m/z from a solution of 2 μg/μl sodium iodide in 50/50 isopropanol/water will contain only m/z and its fragments. The intensity of the largest fragment ion will be less than 5% of the intensity of the precursor ion. MS/MS data will be acquired over the mass range 100 8,000 Da, with collision energy of 10 ev.
