-LG Mechanical Descriptions
Instrument Housing
The MAX300
™
-LG may be located in a laboratory or office type environment. The
exhaust from the vacuum pumps may contain potentially hazardous or toxic substances
and must be vented in a safe manner. Electrical power and signal wiring to the instrument
must be consistent with conditions and meet all applicable local building codes. The
MAX300
™
-LG is intended for “bench top” operation.
Mass Spectrometer Hardware
The analyzer section of the system is a quadrupole mass spectrometer. This device
performs the ionization, mass filtering, and detection of the specified components. For
proper operation the system must be kept under vacuum. The mass spectrometer portion
of the MAX300
™
-LG can be accessed by removing the covers from the enclosure.
The instrument cover has two removable panels for user performed maintenance. To
remove the top front cover, pull straight up to disengage the spring loaded latches. Once
the top cover is removed, the right front cover may be pulled to the right to disengage its
latches. If needed the rear cover can be detached after removing the 4 screws on the back
of the instrument that hold it in place.
After removing the covers of the enclosure the internal mechanical assemblies can be
accessed. The AC switch is located at the bottom left of the enclosure. The mass
spectrometer’s vacuum system is contained within the enclosure on a rotateable mounting
system for easy maintenance. The enclosure contains the vacuum pumps (both
mechanical and turbomolecular), quadrupole controller (QC), ionizer, mass filter, and
detector(s).
Vacuum Chamber
The vacuum chamber has five all metal sealed high vacuum ports to connect components
to the chamber. The ionizer assembly, detector and turbomolecular pump use 4 1/2inch
