ABSTRACT:
Apparatus and process for detecting the products of either liquid or gas chromatographic analysis, which products may be either radioactively tagged or not tagged. In one aspect, it provides a moving wire apparatus for conveying a liquid chromatographic sample through a combustion furnace, where the combustion products are conveyed to a catalytic system. Non-radioactive samples are routed through a nickel catalytic converter; and thence, to a flame ionisation detector. Radioactive samples are conveyed from the combustion furnace through either a copper-oxide or an iron catalytic furnace, depending upon whether the sample is tagged with Carbon-14 or tritium. The products of the catalytic furnaces are detected by means of a radioactive detector. Means are also provided for introducing gas chromatographic products into the system for detection.
