Separating column for gas chromatography

摘要

The separating column, for gas chromatography, is a construction with at least one base plate, at least one cover plate, a geometric channel assembly in the base plate to be covered by the cover plate with gas-tight bondings between them to give the column. Gas-tight connections give a feed at one end of the channel and an outlet at the other end. Also claimed is a mfg. process, where the channel is engraved in the base plate.
