Contamination Issues
Chemical noise is always present in any mass spectrometer. As a result, the high sensitivity of
the mass spectrometer can cause new users to confuse background with a contamination
problem. Additionally, the spectra shown in Xcalibur Tune and Real-Time Display are
auto-normalized, which can make the background appear high-level.
