Maintain the relative humidity of the operating environment between 40 and 80 percent,
with no condensation.
Operating a TSQ Quantum XLS or TSQ Quantum GC system in an environment with very
low humidity can cause the accumulation and discharge of static electricity that can shorten
the life of the electronic components. Operating the system in an environment with high
humidity can cause condensation, oxidation, and short circuits. It can also cause dust to
accumulate that can block filters on cooling fans.
To ensure that your laboratory is always within the required temperature and humidity
specifications, Thermo Fisher Scientific recommends that you equip your laboratory with a
temperature/humidity monitor.
Keep floors free of vibration caused, for example, by equipment in adjoining locations.
Because of the natural vibration of the forepump during operation, install the forepump on
the floor beneath the mass spectrometer and not near the system on the workbench.
Good lighting makes any work area more enjoyable. Thermo Fisher Scientific recommends
that you use a small, high-intensity lamp when cleaning the mass spectrometer components.
Ensure that the air in your laboratory is free from excessive dust, smoke, or other particulate
matter in excess of 5 μm—that is, fewer than 3 500 000 particles per cubic meter (100 000
particles per cubic foot).
Dust can clog the air filters, causing a reduction in air flow around electronic components.
Dust on electronic components can act as an insulating blanket, which reduces the transfer of
heat from the components to the surrounding air.
