An Experimental Investigation of Continuous Gas Chromatography Using Pseudo-Random-Binary Sequence

An Experimental Investigation of Continuous Gas Chromatography Using Pseudo-Random-Binary Sequence

A series of experiments, in which the sample gas of a gas chromatograph has been perturbed with a pseudo-random binary sequence, is described. The detector response was cross correlated with the input to obtain the system impulse response, which, in this case, is proportional to the chromatogram. Th...
