State-of-the-art platforms
that define precision

Every analytical challenge requires the right instrument. Our suite of mass spectrometry platforms ensures optimal technology for each project.

GC-MS
Gas Chromatography–Mass Spectrometry
The gold standard for volatile and semi-volatile compound analysis. Ideal for organochlorine, organophosphate, and pyrethroid pesticide screening in complex food and environmental matrices. Electron ionization provides reproducible, library-searchable spectra for confident compound identification.
Volatile CompoundsEI IonizationSIM / ScanLibrary Matchingppb Sensitivity
LC-MS/MS
Liquid Chromatography–Tandem Mass Spectrometry
Versatile and highly sensitive platform for polar, ionic, and thermolabile analytes. Triple quadrupole MRM mode delivers unmatched selectivity for multi-residue pesticide methods, mycotoxins, and pharmaceutical compound quantification in complex matrices.
Polar CompoundsESI / APCIMRM ModeHigh ThroughputCarbamates
Q-ToF
Quadrupole Time-of-Flight Mass Spectrometry
Our flagship high-resolution platform delivering sub-5 ppm mass accuracy for exact mass determination, unknown compound elucidation, and intact protein characterization. Indispensable for biopharmaceutical characterization, metabolomics, and regulatory suspect-screening workflows.
