Mass-flow control system utilizing flow-feedback for gas chromatography

Creator:: Dodo, Gerald Haruo
Abstract:: A unique mass-flow control system for the carrier gas in gas chromatography is described and evaluated. Carrier gas flow is controlled by a flow sensor, feedback electronics, a flow-control valve and a microcomputer. The flow-rate is monitored by a mass-flow meter by this system and the flow is adjusted in...
