UPLC-Orbitrap-MS/MS (Orbitap Exploris 120)
Ultra performance Liquid chromatography-mass spectrometry (UPLC-MS) combines the physical separation capabilities of liquid chromatography with the mass analysis capabilities of mass spectrometry (MS). This high resolution mass spectrometry provides structural identity of the individual components with high molecular specificity and detection sensitivity, Therefore, may be applied for identification in a wide range of sectors including biotechnology, environment monitoring, food processing, and pharmaceutical, agrochemical, and cosmetic industries.
UPLC-Triple Quadrupole-MS/MS (Waters Xevo TQ MS, Masslynx SW)
Ultra performance Liquid chromatography-mass spectrometry (UPLC-MS) combines the physical separation capabilities of liquid chromatography with the mass analysis capabilities of triple Quadropole mass spectrometry (MS). This instrument is wiedly used to advance the field of plant metabolomics, especially for profiling of secondary metabolites in plants, and for quantitation analysis of natural products (in ppb levels).
GC-MS (Agilent GC-7890A, MS- 5975C, CTC PAL Injector, MassHunter SW)
Gas chromatography-mass spectrometry (GC-MS) combines the features of gas-chromatography and mass spectrometry to identify different substance (volatile or “made volatile”) . Applications of GC-MS include drug detection, fire investigation, environmental analysis, explosives investigation, and identification and quantitation of material samples obtained from planet.
