Temperature indicator
Exhibit no. 937
Temperature needs to be precisely set and measured in various parts of mass spectrometers.
Depending on the instrument design, temperature control can be required during ionization, ion transfer, mass analysis, ion detection or signal processing. Some instruments also use elevated temperature for cleaning the instrument. The baking procedure removes surface deposits, grease, water and other unwanted material.
The picture shows temperature indicator for heated zones in the ion source of double-focusing mass spectrometer MS902 manufactured by AEI Scientific Apparatus Ltd. in 1969.
