Waters has introduced the new Xevo G3 QTof system, a high-performance, benchtop mass spectrometer for characterising and quantifying thermally-fragile molecules in applications such as biotherapeutics, forensics, metabolite identification, metabolomics and extractables and leachables. The Xevo G3 QTof system is up to 10× more sensitive than its predecessor at transmitting thermally fragile molecules and excels at measuring and characterising denatured or native proteins, peptides and other biotherapeutics. Waters have engineered the Xevo G3 QTof system to reliably give scientists both reproducible and accurate qualitative and quantitative information about molecules in their samples whether in very small or very large amounts.
