Screening of residual pesticides in food with two different columns

In recent years, with increases in the number of pesticides and the diversification of substances under investigation, there have been calls for quick and high-accuracy screening for residual pesticides in foods using GC-MS.
The Quick-DB database includes mass spectra, retention times, and calibration curves for 478 pesticide components. It can be used to quickly calculate semi-quantitative values without requiring analytical standards.
If a pesticide peak is detected, it is essential to check for potential interference from co-eluting contaminants to insure highly accurate screening. One of the ways for checking is to analyze the samples with two columns with different types of stationary phase. For this purpose, the Twin Line MS system is very useful because it enables the installation of two types of columns to one MS.
The Quick-DB contains information compatible with two different columns, so that it can also be applied to the Twin Line MS system. In this Data Sheet, residual pesticides in foods were analyzed by applying Quick-DB and the Twin Line MS system.
