Creating endless possibilities LabSolutions Insight Explore ™

Diverse analytical needs can be met Software supports everything from qualitative analysis to quantitative analysis

The OAD-TOF system can be used in combination with various options compatible with the LCMS-9050. The DPiMS ™ Explore software not only facilitates quantitative analysis of a large number of samples, but also comes with
QT, Kit for Direct Probe Ionization Mass Spectrometer, can be installed in place of the standard ESI unit for rapid features for reliable library searching, elucidation of compound structure and sample composition, and multivalent
analysis with simple pretreatment. It can also be connected to the Nexera UC supercritical fluid chromatography ion analysis, making full use of MS data with high resolution and mass precision.
