Create Methods Easily from the Database

The MRM information in this method package is controlled by LabSolutions Connect (option). With LabSolutions Connect, you can call up the information needed from the database by loading a text file, and then easily create an analysis method. In addition, this method package contains text files (search lists) of components subject to the regulations, enabling the easy creation of an analysis method file for these components. 
The database and search lists can be customized for use in conjunction with components to be analyzed by the user.

 

Improve the Shape of Peaks for Polar Compounds via Co-Injection

Co-Injection of Water Using the Pretreatment Mode in the SIL-30AC Autosampler

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 only by the SIL-30AC.

 

Smooth Analysis of Multiple Analytes with LabSolutions Insight

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.

Precaution
LabSolutions LCMS Ver. 5.86 or later is required.
