Example of GC system adsorption of pesticide spectra
Time of Update: 2021-09-08
After a period of sample injection in the GC, the system is covered by non-volatile impurities, which will affect the peaks of some organophosphorus pesticides with strong polarity .
Examples of improper chromatographic peak integration
Time of Update: 2021-09-07
Examples of improper chromatographic peak integrationThe peak area of the chromatographic peak directly determines the pesticide content, so the baseline and starting point of the integration should be accurate .
Example of inverted peak spectrum of ECD detector
Time of Update: 2021-09-07
The reason for the higher possibility of inverted peaks is firstly the contamination of the detector and secondly the problems of the chromatographic column .
