| S1A | Siliceous earth for gas chromatography has been flux-calcined by mixing diatomite with Na₂CO₃ flux and calcining above 900 ℃. The siliceous earth is acid-washed, then water-washed until neutral, but not base-washed. The siliceous earth may be silanized by treating with an agent such as dimethyldichlorosilane to mask surface silanol groups. | Shimalite W AW Shimalite W AW-DMCS Chromosorb W HP Chromosorb W AW |
| S1AB | The siliceous earth as described above is both acid- and base-washed. | Chromosorb W-HP |
| S1C | A support prepared from crushed firebrick and calcined or burned with a clay binder above 900 ℃ with subsequent acid-wash. It may be silanized. | Shimalite AW Shimalite AW-DMCS Chromosorb P AW Chromosorb P AW-DMCS |
| S1NS | The siliceous earth is untreated. | Shimalite W NAW Chromosrob W NAW |
| S2 | Styrene-divinylbenzene copolymer having a nominal surface area of less than 50 m² per g and an average pore diameter of 0.3 to 0.4 µm. | Sunpak-H Chromosorb 101（not available as capillary column） |
| S3 | Copolymer of ethylvinylbenzene and divinylbenzene having a nominal surface area of 500 to 600 m² per g and an average pore diameter of 0.0075 µm. | Sunpak-A Porapak Q |
| S4 | Styrene-divinylbenzene copolymer with aromatic - O and N groups, having a nominal surface area of 400 to 600 m² per g and an average pore diameter of 0.0076 µm. | Shimalite F Chromosorb T |
| S5 | 40- to 60-mesh, high-molecular weight tetrafluoroethylene polymer. | Shimalite F Chromosorb T |
| S6 | Styrene-divinylbenzene copolymer having a nominal surface area of 250 to 350 m² per g and an average pore diameter of 0.0091 µm. | Sunpak-P Porapak P Chromosorb 102 |
| S8 | Copolymer of 4 - vinyl - pyridine and styrene - divinylbenzene. | Porapak S |
| S9 | A porous polymer based on 2,6-diphenyl-p-Phenylene oxide. | Tenax TA |
