A sampling cone of a mass spectrometer is disclosed having a metallic boride coating such as titanium diboride.

Mass spectrometer sampling cone with coating

A mass spectrometer includes an Electron Impact ('EI') or a Chemical Ionization ('CI') ion source, and the ion source includes a first coating or surface. The first coating or surface is formed of a metallic carbide, a metallic boride, a ceramic or DLC, or an ion-implanted transition metal.

Ion source with surface coating

The invention relates to a method of derivina improved data from a mass spectrometer. The method includes operating the mass spectrometer in a mode enabling quantitation; assigning a threshold value for the total ion current (TIC) above which at least MS and/or MSMS data is desired; and triggering the mass spectrometer out of the mode enabling quantitation into at least an MS and/or MSMS mode when said TIC rises above the threshold but triggering only at such time at or after a confirmed TIC maxima has been reached.
