Abstract
In a chromatographic analysis system a bypass conduit operating in parallel with a chromatographic separation column diverts a portion of the sample fluid directly to the chromatographic detector prior to elution through the chromatographic separation column of the remaining portion of the sample material. Comparison of the detector response to the bypassed portion of the sample with the detector response to selected constituents or groups of constituents exiting the chromatographic separation column is used to normalize the analysis response to one or more constituents or groups of constituents eluted through the chromatographic separation column.
