Examples of improper chromatographic peak integration
The peak area of the chromatographic peak directly determines the pesticide content, so the baseline and starting point of the integration should be accurate
Figure 2-27 The baseline position of the left chromatographic peak integration is incorrect
In another case, when two adjacent peaks have not reached baseline separation (Figure 2-29), if the chromatographic conditions cannot be completely separated, then split peak integration should be performed (Figure 2-30)
Figure 2-28 Chromatographic peak integration error with retention time of 13.
Figure 2-29 The peak with impurity at the retention time of 9.
Figure 2-30 Split peak integration for chromatographic peaks that cannot be separated by baseline
