Page 28: Operation
If there are step changes in the mass number, it takes several ms (depending on the size and direction of the step and the type of QMH) until the HF and DC values stabilize in the new state. Pfeiffer Vacuum control units take this into account in the integrated software. -

M , the direction of the step re- sponse, the QMH type and the required accuracy of measurement. Pfeiffer Vacuum recommends ex- perimenting to optimize the waiting periods, in particular for fast measuring speeds. This is the only way to find the best compromise between speed and accuracy of measurement. -
Page 43: 1Apparent Peak Position And Line Width
Appendix 15.2.1 Apparent peak position and line width The apparent mass position depends on the line width ΔM (that is, on the resolution). This shift of the peak maxima with the line width is a natural phenomenon of the quadrupole mass spectrometer. For this reason, the position of the peak top on the mass scale is not an accurate indicator of the mass number. -

Appendix 15.2.4 Deviations from M and ΔM The diagrams show how the deviations from the reference values can be determined. Here dM is the deviation from the setpoint of the mass position M and dΔM is the deviation from the setpoint of the line width ΔM. -
