Application

Supel^™-Q PLOT fused silica capillary column was used with headspace SPME-GC, used for analysis of cyanide in blood. It may also be used as an extraction device, with SPME coupled with liquid chromatography-tandem mass spectrometry (LC/MS/MS), for the determination of five estrogens, estrone, 17ß-estradiol, estriol, ethynyl estradiol, and diethylstilbestrol in environmental waters. It may also be used to separate water from volatile organic compounds (VOCs) in direct aqueous injection-gas chromatography/mass spectrometry (DAI-GC/MS) method, used for trace analysis of VOCs.

General description

Supel-Q^™ porous layer open tubular (PLOT) capillary GC column contains divinylbenzene (DVB) polymer, which acts as a stationary phase. It effectively resolves carbon dioxide from the hydrocarbon gases. It is also highly suitable for separating much higher boiling hydrocarbons.

Application: This column exhibits very little bleed, even at its maximum temperature, and effectively resolves carbon dioxide and C1-C4 hydrocarbons at above ambient temperatures. It is also suitable for analyses of sulfur gases, alcohols, ketones, aldehydes, and many polar compounds. Gasoline and other petroleum fractions can be analyzed as well. USP Code: None Phase: Divinylbenzene Temp. Limits: Subambient to 250 °C (isothermal or programmed)
