These general specifications for the operating environment help
ensuring continued high performance of the system.
Good lighting makes any work area more enjoyable. Since a lot of work
is done on the computer terminal, it may be convenient to have
dimmed lights to reduce eyestrain. A small, high-intensity lamp is
recommended for cleaning instrument components, source inspection,
and manipulation of small components. Contact your local safety officer
for advice and regulations on adequate working place conditions.
Particulate matter might contaminate the samples, the sample
introduction as well as the ion source and may limit the background
level of the instrument.
The air in your laboratory must not contain excessive dust, smoke, or
other particulate matter. For reference, the air should contain fewer than
6
35 × 10 particles per cubic meter (1 × 10
excess of 5 μm.
Dust can clog the air filters, causing a reduction in air flow around
electronic components. Dust will also form a layer on electronic
components that will act as an insulating blanket and thus reduce the
heat transfer from the components to the surrounding air.
The quality of power supplied to your system is very important for its
performance.
Below are definitions for the most common voltage disturbances:
•
Harmonic distortion is a high-frequency disturbance that might
affect operation of your system. This disturbance appears as
distortion of the fundamental sine wave.
•
Slow average is a gradual, long-term change in average root mean
square (RMS) voltage level, with typical durations greater than 2 s.
•
Sags and surges are sudden changes in average RMS voltage level,
with typical durations between 50 s and 2 s.
•
Transients (or impulses) are brief voltage excursions of up to several
thousand volts with durations of less than 50 s.
