The Thermo Scientific Q Exactive Combined Quadrupole Orbitrap mass spectrometer quickly identifies, quantifies, and confirms more compounds. The benchtop LC-MS/MS system combines quadrupole parent ion selectivity with high resolution and accurate mass (HRAM) Orbitrap detection for superior performance and versatility. The Q Exactive mass spectrometer is ideal for non-target or target compound screening, as well as for a wide range of qualitative and quantitative applications for drug discovery, proteomics, environmental and food safety, clinical research and forensic toxicology.
