Instrument and method for analyzing complex substances |
| abstract |
A chromatographic apparatus including a chromatographic column through which a fluid carrier medium flows. A complex mixture is introduced into the carrier gas medium prior to the column and is resolved into individual compounds which elute at separate times with the continuing passage of the carrier medium. These compounds are introduced separately into a pyrolyzer which reduces them to pyrolytic fragments. The carrier medium with the pyrolytic fragments in it is introduced into another chromatographic column and eluted therefrom at separate times by the continuing flow of the carrier medium. These fragments are detected and cause a chromatogram unique to the compound to be traced. Once a compound has been eluted from the first column, the flow of carrier medium through that column is halted and that column is isolated from the pyrolyzer and second column so that other compounds will not elute and interfere with the pyrolytic fragments from the prior compounds. |
