34 flash & tlc flash Flash Chromatography Flash chromatography is a simple, often automated, low to medium pressure liquid purification technique used to rapidly isolate desired compounds or reaction intermediates from simple or complex mixtures. Purifying these important components at sufficient quantity and purity can be challenging when performing a flash separation using bare silica. Selecting an appropriately bonded stationary phase with suitable alternate mobile phases may be necessary since: Mixtures vary in complexity, including the number of components, compound class, polarity, and molecular weight, etc. Bare silica may not be the optimal stationary phase for the compounds due to lack of retention, solubility, poor peak shape and compound stability, etc. Selecting the Optimum Stationary Phase Media phases differ in polarity according to the graphic below and changing stationary phases is a powerful tool to achieving successful flash separations. Polar Silica Si-OH Amino Diol C8 Si-CH NH Si-H(OH)CH (OH) SI-(CH ) 7 CH 3 Grace Flash Cartridges Non-Polar Media Selection Guide Phase Selection Guide Compound Class Si C8 Amino Diol Alkaloids X X X Amino Acids X Aromatics X X X X Carbohydrate X X Drug Intermediates X X Basic Drug Products X X X Flavonoids X Glycosides X X X Isomers X X Lipids X X Lignans X X Polyphenols X X Saponins X X Steroids X Tannins X Terpenes X X X Vitamins X X X X Xanthones X X X Peptides <5000mw X X Oligonucleotides <5000mw X Nucleosides/tides X Pegylated X X Secondary Metabolites X Tips For compound classes for which multiple media options are indicated, phase preference is further determined by the extent of sample component acidic/basic nature and overall polarity. For maximum resolution, reversed-phase C8 using aqueous mobile phase is often selected as the primary option, especially for polar samples having a strong affinity for silica. For difficult purifications of closely-related compounds, smaller particle media packings or higher pressure techniques may need to be employed to achieve separation. Larger, sensitive or charged molecules may require lower flow and pressures common for ion exchange, size exclusion or affinity chromatographic techniques (vaccines, DNA, intact proteins, and peptides >5KDa). Get the most out of your flash applications by choosing Grace flash cartridges, the only flash cartridges designed by a silica expert for ideal chromatographic performance. Grace has balanced small particle size media with high loading capacity and efficient packing methods to produce the perfect flash cartridge. Why Do Grace Cartridges Perform Better?. Small Particle Size A smaller particle size increases resolution. Tighter particle size distribution and minimal fines keep back pressure low.. High Purity Silica Grace's 30 years of chromatography experience combined with 80 years of silica manufacturing expertise has allowed Grace to produce optimized silica designed for flash chromatography. 3. Efficient Column Packing A tightly packed silica bed increases cartridge efficiency and prevents voids and channeling that cause poor resolution. Flash chromatography, like HPLC, benefits greatly from optimized packing procedures. 4. Strict Quality Control Grace flash cartridges are characterized with more than 5 tests from the silica to the packed cartridges to ensure consistent lot-to-lot performance. A quality assurance certificate is provided with each box of cartridges. 3

35 flash & tlc Reveleris Flash Cartridges High resolution High loading capacity High pressure (00 psig/4bar) Auto-recognition by Reveleris flash system The silica packed in Reveleris cartridges is specifically designed to increase cartridge efficiency and therefore resolution of closely eluting compounds, in some cases greater than two times better resolving power over typical packings. Greater efficiency enables more peaks to be baseline resolved and results in increased sample purity as well as decreased fraction volumes. Additionally, by increasing sample loads on a given cartridge size and elevated pressure capability, sample throughputs and yields increase and overall purification costs are lowered. Luer design is compatible with most systems. Reveleris flash cartridge Loading Capacity Comparison Competitor flash cartridge. Toluene.

Two methods are commonly used to determine the optimum mobile phase composition. Resulting data is used to automatically generate flash gradient profiles in the Reveleris Navigator software. For normal phase purifications, thin layer chromatography (TLC) plates made with the same high purity silica as used in the Reveleris and GraceResolv cartridges are used to ensure the same selectivity and allow simple scale-up. For reversed-phase applications, Reveleris C8 scouting columns are the perfect method development tool to optimize mobile phase choice. Flash TLC Plates Size Qty.

Tenax -TA (GC) Polymer Tenax -TA porous polymer is based on,6-diphenyl-pphenylene Oxide. It has replaced Tenax -GC polymer and can be used as a packing and as a trapping material. Both the EPA and NIOSH specify the use of Tenax polymer in their standard methods. It is particularly useful for the analysis of high boiling compounds such as alcohols, polyethylene glycols, diols, phenols, monoamines and diamines, ethanolamines, aldehydes, ketones and chlorinated aromatics. Tenax -GR Polymer Tenax -GR polymer contains 3% graphitized carbon as an integral part of the material. This is not an admixture; the graphitized carbon is co-precipitated with the Tenax polymer. The resulting material gives higher breakthrough volumes for most materials, yet is less water retentive than Tenax -TA polymer. When using this material for packing GC columns, better peak symmetry is observed. Surface area is 4.m /g. HayeSep Porous Polymer Pre-purified porous polymers for GC Less bleed and shrinkage than other porous polymers Cleaned and conditioned to 00 C (65 C for N & T) HayeSep polymers were developed to solve room temperature separation of N, O, Ar and CO; ppm HO in the presence of HCl, Cl, etc. The HayeSep D polymer series better separates the fixed gases to the C hydrocarbons. Porapak Packings Porapak GC packings are cross-linked polymers that can be used directly in GC columns without a stationary phase coating. Acetone washing of Porapak GC packings improves their performance.

55 spe and filtration SPE Introduction SPE method development typically contains four steps: Step : Condition The conditioning step is composed of two substeps; the first activates the sorbent ligands, the second equilibrates the sorbent bed. Step : Load In the load step, sample is applied to the SPE device. Matrix and flow rate are optimized to quantitatively retain target analytes. Step 3: Wash In the wash step, choose a solvent that elutes impurities but retains target analytes. Often the second conditioning solvent is a suitable wash solvent. Step 4: Elute The elution step ideally removes all target analytes with minimal solvent to maximize sensitivity. Sometimes this requires a combination of solvents to break both the primary and secondary interactions. Reversed-Phase Extraction Procedure Mechanism: Bind moderately polar to non-polar compounds from a polar sample matrix. Normal Phase Extraction Procedure Mechanism: Bind polar compounds from a non-polar sample matrix. Ion-Exchange Extraction Procedure Mechanism: Bind charged (negative/anionic or positive/cationic) compounds. General Method Development Procedures Step Condition ~ 4 bed volumes Step Load Step 3 Wash ~ 6 bed volumes Methanol followed by water IPA followed by hexane Methanol:water (50:50) followed by low ionic strength (0.M) buffer Process sample at a flow rate of 5mL/min Process sample at a flow rate of 5mL/min Apply slowly: less than or equal to ml/min ion exchange kinetics are slower than reversedor normal phase Water or water:methanol (95:5) Hexane or hexane:ipa (98:) Methanol:low ionic strength (0.M) buffer (0:90) Step 4 Elute ~ 3 bed volumes Methanol or acetonitrile. May need to add strong acid or base to organic solvent to break secondary interactions. IPA, ethyl acetate, acetone, or hexane:ipa (50:50) High ionic strength (0.5M.0M) buffer or modify ph such that the analyte is uncharged. May need to add organic to break hydrophobic interactions. spe tech tip To calculate sorbent bed volume, use 50µL for every 00mg of sorbent. tech tip Retention capacity describes the total amount that an SPE sorbent will bind. This includes all compounds retained analytes of interest as well as the contaminants. tech tip The minimum elution volume recommended in the bed size chart above will offer best sensitivity, but more solvent may be required depending on the application.

The sensor not only detects and alerts you to leaks, it also communicates with the vacuum pump. If a change in vacuum is detected due to mobile phase flow rate changes, the pump can compensate by changing its speed. The validation output records vacuum level to satisfy ISO and system validation requirements.

A number of options are available for packed column tubing. The most inert material is glass, which should be used for active compounds. Glass-lined tubing and AT Steel provide the inert surface of glass combined with the mechanical strength of a metal column. Metal tubing provides an economical and rugged column for suitable application. Passivated nickel tubing can frequently be used with active compounds such as phenols and amines. Stainless steel tubing is recommended for hydrocarbon, fixed gas, and solvent analyses where column inertness is less of a concern. PTFE tubing is extremely inert, but due to temperature limitations and poor column efficiency, PTFE is generally only recommended for the analysis of corrosive gases which are too reactive for glass. related products See page 75 for the Clean-cut tubing cutter designed to make clean square cuts on PEEK tubing. 7
