摘要：The output signal of an effluent detector, disposed, for example, downstreamof a liquid phase chromotography column, is digitalized and then compared to a LEVELsignal, fixed in relation to the base line of the detected signal, plus a deviation value (LO).A slope threshold is defined. As long as the slope of the detected signal is below thethreshold, the pilot signal follows the detected signal. When the slope of the detectedsignal is higher than the threshold, a peak has occurred, and the value of the pilot signallocked, at least during a pre- established time. Thereafter the pilot signal resumes itsevolution substantially parallel with the base line. This enables an outstanding detectionof the useful peaks in the analysis of effluents.
