ABSTRACT:
Proposed is an improvement in a detection and recording system in the conventional chromatography in which the chromatographic signals are detected by means of a single detector sometimes to cause difficulties in resolution of the signal of minor component masked by the major component or in separation of two components having about the same retention times. The improvement comprises using two or more detectors to generate signals with a phase difference and recording the differential signal between the two signals obtained in the plurality of detectors.
