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 dichlorodimethylsi-lane to mask surface silanol groups.
Headspace-gas chromatography: The influence of sample volume
The role of the volume of the sample and the sample vial in equilibrium headspace-gas chromatography is discussed. A new term, thesample phase fraction (ΦS) is introduced. It is shown that if the value of ΦS is kept constant, the vial's volume has no influence on the “sensitivity” of the headspace analysis (which is proportional to the concentration of the analyte in the headspace). In a

Fine-Threaded vials ND18: Due to the fine thread the vials are sealed gas tight. They are therefore suitable for headspace and solid phase microextraction analyzes. Roll edge and headspace vials ND20: For headspace analyzes, the sample vials must withstand a high internal pressure and therefore have a thicker wall thickness.
