Description
technical field [0001] The present application relates to the field of computer technology, in particular to a chromatographic peak detection method, device, computer equipment and storage medium. Background technique [0002] With the development of computer technology, chromatography is widely used when detecting the content of various compounds in samples to be tested. When using chromatography, it is necessary to calculate the peak area of each chromatographic peak based on the separated chromatographic peaks in the original chromatographic signal. [0003] However, when there is overlap between adjacent chromatographic peaks in the original chromatographic signal or part of the chromatographic signal is incomplete, when multiple detections are performed on the same sample to be detected, for the chromatographic peaks corresponding to the same compound, the results obtained for each detection There may be large differences, and the repeatability of the test results is...
