Chromatographic workstation with fused peak baseline adjusting function

Abstract

The invention provides a chromatographic workstation with a fused peak baseline adjusting function. The chromatographic workstation comprises: a starting baseline unit for connecting a starting point and a falling point to form a preparatory baseline; a penetration determining unit for determining whether a baseline penetrates or not, triggering a baseline updating unit if so and triggering a baseline adjusting unit if not; the baseline updating unit for using points from a first end point to a top point in a point-by-point manner as experiment points if a penetrating point exists, and connecting the experiment points and a second end point to form a new preparatory baseline until no baseline penetrates, and triggering the baseline adjusting unit, wherein the first end point is a starting point, the second end point is a falling point and the top point is the top point of a first peak, or the first end point is a falling point, the second end point is a starting point and the top point is the top point of a last peak; and the baseline adjusting unit for using the newly formed preparatory baseline as an adjusted actual baseline. The chromatographic workstation has the advantages of reduction of the error in the quantitative analysis of the fused peak of a sample to be measured, improvement of the accuracy of quantitative analysis, simplicity and labor saving.

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...
