ABSTRACT:
An injection assembly for short path thermal desorption apparatus used in a gas chromatography-detector unit (GC-DET) for systems, methods and techniques such as a gas chromatography-mass spectrometry system. The short path thermal desorption apparatus has a housing defining an upper compartment, and a desorption compartment. The injection assembly is disposed exterior of the housing and is actuated from a disengaged position to an engaged position with the gas chromatography unit by a suitable gas powered cylinder assembly mounted in the upper compartment and includes a desorption tube for collecting and storing the sample compound to be analyzed, means for passing a carrier gas therethrough to desorb the sample component when the desorption unit is heated, and a needle injector for passing the desorbed sample component to the GC-DET system for identification and quantification of the sample component. The desorption tube is operatively associated with a desorption block assembly having a pair of coating heating blocks made of materials having a high coefficient of heat transfer and mounted for bilateral opening and closing about the desorption tube when the injection assembly is moved from the disengaged to the engaged position.
