Specifications
USP Phase Descriptions
| Method | Support Material Description | Phase Name |
| S1A | Siliceous Earth for Gas Chromatography has been Flux-calcinated by mixing diatomite with sodium car-bonate, flux and calcining above 900°C. The siliceous earth is acid-washed, then water-washed until neutral, but not base-washed. It may be silanized by treating with an agent such as dichlorodimethylsilane to mask surface silanol groups. |
Chromosorb WAW Chromosorb WAW-DMCS Chromosorb WHP |
| S1AB | Siliceous Earth for Gas Chromatography has been Flux-calcinated by mixing diatomite with sodium car-bonate, flux and calcining above 900°C. The siliceous earth is acid-washed, then base-washed and then water-washed until neutral. It may be silanized by treating with an agent such as dichlorodimethylsi-lane to mask surface silanol groups. | Chromosorb WHP |
| S1C | Support made by crushed firebrick and calcinated or burned with a clay binder above 900°C with subsequent acid-wash. It may be silanized. |
