Miniature HPLC device

摘要

A liquid chromatography device comprises one or more liquid reservoirs (3) for a liquid medium, a sample reservoir for a sample to be analysed and a chromatography column (4) in fluid communication with the liquid reservoir (3) and the sample reservoir (5). The device further comprises a gas reservoir (1) for containing a volume of gas under pressure to force liquid from the liquid reservoir (3) through the chromatography column (4), in use.
