Phase:
USP Code: None
Phase:
- Stabilized
- Proprietary
- Subambient to 275 °C (isothermal or programmed)
Applicazioni
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.
