Abstract:
A method for analyzing complex mixtures of organic chemical compounds comprising the steps of:a) separating said compounds using a chromathermography separation apparatus operating at a controlled temperature;b) coupling an output of said chromathermography apparatus to an input of a gas chromatography apparatus;c) repeating steps (a) and (b) at at least one other temperature to obtain a plurality of gas chromatograph output traces at neighboring ones of said controlled temperatures; andd) determining a quantity of at least one of said compounds in said mixture by analyzing at least two of said plurality of traces, wherein said analyzing comprises identifying a quantity of said at least one of said compounds in said mixture from each of said at least two of said plurality of traces, and said determining comprises combining said quanitity identified from each of said at least two traces.
