PESI MS Solution Software Data Analyzed Using LabSolutions LCMS

PESI MS Solution software is used to control the probe, edit MS method files, and start measurements. The system can be used for a wide variety of applications, such as for library searches based on mass spectra obtained from product
Scan range and SIM settings are specified via the method editing window in LabSolutions LCMS software. Analysis can be started ion scans, for quantitative analysis based on ion chromatograms obtained from MRM, or for multivariate analysis using scan data.

easily by selecting the probe control mode and MS method in PESI MS Solution. During analysis, the status can be confirmed in the Because the postrun analysis functionality in LabSolutions LCMS is used, data can also be easily compared to LC/MS/MS data.
