Keep the laboratory room temperature between 18 and 27 °C (64 and 81 °F).
All electronic components generate heat while operating. This heat must be dissipated to the surrounding air for the components to continue to operate reliably.
There must be a good flow of air around the system, and the air conditioning system must be capable of maintaining a constant temperature (within the temperature specification given above) in the immediate vicinity of the system. We recommend the installation of an air conditioner if the specified limits are exceeded due to unfavorable climatic conditions. Preferably, the air conditioner should be equipped with a flow controller valve and PID microprocessor control (available e.g. from Landis & Gyr, Polygyr RWX series, see www.landisgyr.com). This ensures that the temperature drifts within the limits given above.
NOTICE
Do not place the mass spectrometer below an air duct, near windows, or near heating and cooling sources. Temperature fluctuations of 0.5 °C or more over a 10-minute period can affect instrument performance.
If the temperature in the laboratory has changed for more than 2 °C since the last mass calibration, Thermo Fisher Scientific strongly recommends that you refresh the mass calibration.
NOTICE
Do not put the mass spectrometer below an air duct, near windows, or near heating and cooling sources. Temperature fluctuations of 1 °C per hour can affect instrument performance.
If the temperature in the laboratory has changed for more than 2 °C since the last mass calibration, Thermo Fisher Scientific strongly recommends that you refresh the mass calibration and isotope ratio calibration.
TIP
The bakeout time required to achieve the operating vacuum in the UHV chamber increases with the temperature in the laboratory. To quickly achieve the optimal operating vacuum, Thermo Fisher Scientific recommends keeping the laboratory temperature at the lower end of the range.
