ABSTRACT:
Apparatus for processing the output signal of a gas chromatograph. An interface device receives the analog output signal and digitizes it, reducing the effects of noise and preparing the signal for processing by a digital microprocessor. The microprocessor detects and measures peaks in the signal and determines the desired identification (in order of ascending molecular weight) and concentration (peak amplitude) data. A logarithmic output signal is produced for displaying output signals with wide dynamic ranges on a strip chart recorder.
