20ml gas chromatography vials with aluminum cap Sigma

Chromatography Research Supplies (CRS) has developed a moisture filter specifically targeted to SFC end-users in petrochemical analysis using carbon dioxide as their mobile phase. In this specific application, the adsorption properties of the typical 5A or 13X molecular sieve media can cause rapid heating of the purifier cylinders from CO2

Apr 16, 2004 · The best global response was reached when the headspace volume was around 20 ml (in vial of 40 ml), salt concentration was close to 300 g/l, and the extraction temperature near to 10 °C. For practical reasons, the two latter were the values chosen instead of the previously indicated (294.3 g/l and 9.9 °C).

Jan 01, 1988 · The disks were placed in 20-ml headspace vials (Perkin-Elmer), which were hermet- ically sealed by crimping an aluminum cap containing a PTFE coated butyl rubber septum (Perkin-Elmer) onto the vial. The sealed vial was placed in the sample carriage of the HS-100 automated headspace sampler and equilibrated for 30 min at 90.
