SP-2560 Capillary GC Column• Application: This highly polar biscyanopropyl column was specifically designed for detailed separation of geometricpositional (cis/trans) isomers of fatty acid methyl esters (FAMEs). It is extremely effective for FAME isomer applications.• USP Code: This column meets USP G5 requirements.• Phase: Non-bonded; poly(biscyanopropyl siloxane)• Temp. Limits: Subambient to 250 °C (isothermal or programmed
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…

Cyclodextrin-based DEX and Astec CHIRALDEX phases are stable, high boiling liquids and make effective CSPs for enantiomer separations by GC. The two lines exhibit complementary selectivity.Cyclodextrins are macromolecules composed of 6 or more D(+)-glucose residues bonded through α-glycosidic linkages. They are classified according to the number of glucose residues they contain: α-cyclodextrins (six residues), β-cyclodextrins…
This column allows highly reproducible analyses of fatty acid methyl esters (FAMEs), specifically the omega 3 and omega 6 fatty acids. It is tested to ensure reproducible FAME equivalent chain length (ECL) values and resolution of key components. Column Details: Phase: Bonded; poly(ethylene glycol) USP Code: G16 Length: 15, 30 m ID: 0.10, 0.25, 0.32, 0.53 mm df: 0.10, 0.25, 0.50
Application: The 35% phenyl equivalent phase provides a higher polarity option compared to columns containing a lower phenyl content, resulting in a greater retention of polar analytes relative to non-polar compounds. Its selectivity is complementary when paired with SLB-5ms for applications that require dual-column confirmatory analysis, such as for environmental analytes (such as pesticides, PCBs, and herbicides). The low…
Elite-1, 100% dimethyl polysiloxane, columns are highly versatile, non-polar, cross-linked general purpose columns that are rugged, exhibiting long column lifetime, low bleed, and high maximum operating temperatures.
The Elite-5 is a 5% diphenyl/95% dimethyl polysiloxane stationary phase. It is regarded as a general purpose, low polarity phase that is the most popular GC stationary phase. The Elite-5 is a crosslinked phase in which all residual catalysts and low molecular weight fragments have been removed providing a tight mono-modal distribution and extremely low bleed.
The Elite-5ms phase (5% 1,4-bis(dimethylsiloxy)phenylene, 95% dimethyl polysiloxane) incorporates a phenyl group in the polymer backbone to improve thermal stability, reduce bleed and make the phase less prone to oxidation. This results in inertness to active compounds and extremely low bleed for sensitive MS applications.
