Abstract
A Time of Flight (TOF) mass analyser comprises an ion source, a detector, an electrode, and a resistive divider comprising first and second resistors. The ion source and the detector define an ion flight path from the ion source to the detector. The electrode is arranged along the ion flight path and receives an output voltage. Thermal expansion produces a first mass shift/Kelvin of detected ions. The resistive divider is thermally coupled to the TOF mass analyser to receive an input voltage and output an output voltage to the electrode. The first and second resistors have respective first and second temperature coefficients that provide a voltage shift/Kelvin to the output voltage to the electrode producing a second mass shift/Kelvin of detected ions, compensating for the first mass shift/Kelvin.
