ABSTRACT:
An improved high resolution chromatograph device operable at column pressures ranging between one and fifty atmospheres absolute measured at the column exit, means for closely regulating the column carrier gas velocity including intermittent stop flow operation, and sample collection chamber means to facilitate contamination free handling and concentration of collected pure sample during spectral or other analysis of eluted samples. Velocity and stop flow control without loss of chromatographic resolution permits matching operation time of chromatograph to that of spectral or other analysis devices.
