LC/MS/MS Method Package for Residual Pesticide Ver. 3

MRM Chromatograms for Pesticides Added to a Tomato Extract (Sample injection volume: 2 μL)

Samples pretreated with the QuEChERS method are extracted with 100 % acetonitrile. Accordingly, the shape of peaks for polar compounds with short retention times is prone to deformation depending on the analytical conditions (figure at right (1)).
A pretreatment program for co-injection is incorporated into the high-speed simultaneous analysis methods for 508 and 646 residual pesticides. Reducing peak shape deformation is possible by co-injecting water with the sample (figure at right (2)).

Note: The co-injection mode is supported by the SIL-40 series and the SIL-30AC.

When analyzing data for multiple components and analytes, everything from batch analysis to the creation of reports can be performed by LabSolutions Insight.
LabSolutions Insight is a software program equipped with quantitative analysis and screening functions. In the analysis window, information is displayed for each target compound and set of measurement data, and both quantitative values and area values can be listed. This allows the user to select the easiest display method for checking the data in accordance with the workflow.

In addition, by using the flagging function, only the results exceeding specified standard values are displayed, improving the analytical throughput of multiple components and analytes subject to the regulations.
