A timed solenoid injector for flow analysis.
Samples can be reproducibly injected into flow-streams by timed switching of a sample stream with a miniature solenoid valve and timer circuit. The device is simpler to assemble and use than the standard rotary valve and a direct comparison under the same operating conditions shows that the solenoid valve is an adequate replacement for the rotary valve.
