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:
USP Code: None
Phase:
- Stabilized
- Proprietary
- Subambient to 275 °C (isothermal or programmed)
Application
SP®-2331 GC column maybe used in high-resolution gas chromatography, with mass selective detection for the analysis of polychlorodibenzodioxins and polychlorodibenzofurans with 1 to 8 chlorine substituents.
Other Notes
We offer a variety of chromatography accessories including analytical syringes
