A Chromatography Workstation with Fusion Peak Baseline Adjustment Function

Abstract

The present invention provides a chromatographic workstation with a fusion peak baseline adjustment function, comprising: an initial baseline unit, which is used to connect the starting point and the falling point to form a preliminary baseline; a penetration judgment unit, which is used to determine whether there is a baseline penetration, and if so, trigger a baseline update unit , if not trigger the baseline adjustment unit; the baseline update unit is used to approach the vertex point by point from the first end point as the experimental point when there is a penetration point, and connect the experimental point and the second end point to form a new preliminary baseline until no more Baseline penetration triggers baseline adjustment unit; the first end point is the starting point, the second end point is the drop point, and the apex is the apex of the first peak; or the first end point is the drop point, the second end point is the starting point, and the apex is the last peak The apex of the peak; the baseline adjustment unit is used to use the newly formed preliminary baseline as the adjusted actual baseline. The invention can reduce the error in the quantitative analysis of the fusion peak of the sample to be tested, improve the accuracy of the quantitative analysis, and save time and effort.

Description

technical field [0001] The invention relates to the technical field of test and measurement, in particular to a chromatographic workstation with a fusion peak baseline adjustment function. Background technique [0002] At present, all chromatographic instruments in the industry are equipped with chromatographic workstations. The chromatographic workstation is equivalent to a host computer. On the one hand, it completes the control of the lower computer (that is, the chromatograph), and on the other hand, it analyzes and processes the chromatographic data collected by the lower computer to achieve Quantitative analysis of the sample to be tested. [0003] The quantitative analysis of the sample to be tested mainly depends on the peak area or peak height of the corresponding peak of the sample. The peak area of ​​a spectral peak refers to the area surrounded by the spectral peak and the baseline, and the peak height of the spectral peak refers to the distance from the peak of...
