11.3.3 Mass number calibration
Procedure:
1. Set a recipe for analogue mode and measure the mass spectrum.
(If peaks are not clear, improve the situation by adding gas flow or increasing the
SEM voltage.)
Purpose: Calibrate the horizontal axis of the mass spectrum. The horizontal axis can
fluctuate according to ambient conditions or if the sensor is contaminated. If
the fluctuations becomes large, the data can become unstable.
Cycle: Calibrate when you exchange the sensor or the ion source, or if the ambient
conditions (temperature, humidity) change, or during a confirmation of
sensitivity.
