Separations is a fundamental scientific discipline focused on the isolation and purification of components from mixtures. Through techniques such as chromatography, distillation, and filtration, separations scientists separate substances based on their physical or chemical properties. This field plays a crucial role in various industries, including pharmaceuticals, food and beverage testing, environmental science, materials research, and more. Explore how separations techniques enable precise analysis, quality control, and the development of innovative products.

SLB-IL60 Ionic Liquid Capillary GC ColumnApplication: Modified (deactivated) version of SLB-IL59 provides better inertness. Selectivity more polar than PEG/wax phases, resulting in unique elution patterns. Higher maximum temperature than PEG/wax columns (300 ºC compared to 270-280 ºC). Excellent alternative to existing PEG/wax columns. Also a good GCxGC column choice. Launched in 2012.USP Code: NonePhase: Non-bonded; 1,12-Di(t…
SLB-IL59 Ionic Liquid Capillary GC Column• Application: Selectivity more polar than PEG/wax phases, resulting in unique elution patterns. Higher maximum temperature than PEG/wax columns (300 ºC compared to 270-280 ºC). Great choice for analysis of neutral and moderately basic analytes. Launched in 2009.• USP Code: None• Phase: Non-bonded; 1,12-Di(tripropylphosphonium)dodecane bis(trifluoromethylsulfonyl)imide• Temp. Limits: Su…
SUPELCOWAX® 10 Capillary GC Column• Application: This column is based on one of the most widely used polar phases, Carbowax 20M, and is a polar column suitable for analyses of solvents, fatty acid methyl esters (FAMEs), food, flavor and fragrance compounds, alcohols, and aromatics. Additionally, this column is a great choice when a polar general purpose column is required.• USP Code: This column meets USP G16 requirements.• Ph…
Equity-5 Capillary GC Column• Application: This popular column is designed for general purpose applications where a non-polar column is required. The low phenyl content provides thermal stability compared to 100% poly(dimethyl siloxane) columns.• USP Code: This column meets USP G27 and G36 requirements.• Phase: Bonded; poly(5% diphenyl/95% dimethyl siloxane)• Temp. Limits: ≤0.32 mm I.D., • Temp. Limits: ≤0.32 mm I.D., ≥2 μm: -…
SPB-5 Capillary GC Column• Application: This non-polar general purpose column provides primarily a boiling point elution order with a slight increase in selectivity, especially for aromatic compounds.• USP Code: This column meets USP G27 and G36 requirements.• Phase: Bonded; poly(5% diphenyl/95% dimethyl siloxane)• Temp. Limits: ≤0.32 mm I.D., • Temp. Limits: ≤0.32 mm I.D., ≥2 μm: -60 °C to 300 °C (isothermal or programmed)• T…
The SPME-LC fiber probes are intended as single-use devices for the extraction of small molecules out of a fluid followed by solvent desorption and LC analysis.Traditional solid phase microextraction (SPME) fibers were developed with common GC type phases, which were primarily designed for extraction of volatile or semi-volatile compounds using thermal desorption as the means of introducing sample into the chromatographic colu…
Carboxen®/Polydimethylsiloxane (CAR/PDMS) SPME FibersSolid Phase Microextraction (SPME) is an innovative, solvent-free sample prep technology that is fast, economical, and versatile. SPME uses a fiber coated with a liquid (polymer), a solid (sorbent), or a combination of both. The fiber coating removes the compounds from your sample by absorption in the case of liquid coatings or adsorbtion in the case of solid coatings. The…
