General description
Application: A highly polar cyanosiloxane column specially tested for analyses of dioxins, specifically tetrachlorodibenzodioxin (TCDD) isomers. Because the phase is stabilized, it has a maximum temperature slightly higher than non-bonded cyanosiloxane columns.
USP Code: None
Phase:
- Stabilized
- Proprietary
- Subambient to 275 °C (isothermal or programmed)
Application
SP® 2331 capillary column may be used in in high-resolution gas chromatography coupled with mass selective detection (HRGC-MSD) for selective separation of 2, 3, 7, 8-tetrachlorodibenzofuran. It was also used in HRGC-MSD for the analysis of chlorinated biphenyls, chlorinated dibenzodioxins, and chlorinated dibenzofurans. It was also used in the gas chromatographic separations of pyrethroid insecticides allethrin and cypermethrin in various achiral and chiral stationary phases.
Other Notes
We offer a variety of chromatography accessories including analytical syringes
