Abstract
An improved gas chromatograph for "on line" use with absorption spectrum analyzers, particularly, infrared spectrometers. The new chromatograph has been adapted for compatibility with a variety of absorption spectrum analysis instruments from the standpoint of cycling time, dimensions, thermal characteristics and convenience in handling extremely small and highly reactive chemical sample materials.
