APPARATUS FOR FEEDING CARRIER GAS TO ON-COLUMN INJECTORS

摘要

An apparatus for feeding carrier gas at constant rate to on-column injectors for capillary and micropacked gaschromatographic columns. The apparatus comprises a constant pressure gas delivering device on operation during the sample injection, and a constant rate gas delivering device on operation during the sample processing stage inside the column. Said two devices are connected in parallel and a switch controls the alternative operation of the same.
