PEAK IDENTIFYING METHOD BASED ON PEAK GRAVITY CENTER

摘要

PROBLEM TO BE SOLVED: To provide a peak identifying method capable of coping with peak shape change when analyzing an unknown sample.;SOLUTION: A method for identifying a component in which an index (time) indicating a gravity center position of a peak is less affected even when a peak shape changes significantly calculates the sum of area values per micro time section from a peak start time to a peak end time as a peak area about a chromatogram of a standard sample, and compares the peak area gravity center time calculated in the same method about a chromatogram of an unknown sample with a peak area gravity center time of the standard sample. The peak area gravity center time is the time lasting till the total of area values per micro time section from the peak start time halves the peak area.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
