Mass accuracy isn’t just a spec – it’s a foundation for trust. If you’re using SIM mode on a quadrupole mass spectrometer, you may be improving sensitivity – but at the expense of visibility. Anything you’re not specifically targeting will be filtered out, making unknowns easy to miss. BenchTOF2™ mass spectrometers remove that compromise. They deliver full-range, quadrupole-like spectra in every run – giving you the sensitivity of SIM with the power to screen comprehensively...
