Method and device for the analysis of effluents for detection of peaks

摘要

P the output signal of a sensor of effluents, for example, after a column of liquid phase chromatography, is scans, then compares the signal level, which is fixed with respect to the base line of the signal detected, increases from a value of difference lo. A threshold slope is defined. As long as the slope of the signal detected is lower than threshold, the pilot signal follows the signal detected. When the slope of the signal detected is which is greater than threshold, it is in the presence of a peak, and it blocks the value of the pilot signal, at least during a time pre-established. After this, the pilot signal returns to its evolution is substantially parallel to the base line. This provides a good detection of the peaks useful in the context of the analysis of effluents. / p
