Technical Description: Inlet
The Rapid Multi-Stream Sampler (RMS) inlet system has been used
successfully with a range of Prima and Sentinel gas analysers. The
unit selects a single gas stream from a number of incoming sample or
calibration gas streams, and some of the selected gas stream is then
delivered to the mass spectrometer for analysis.
Warning!
The notes below must be considered in addition to safety
notes elsewhere in this manual covering the system as a whole.
Depending on the nature of the gases in use (sample and calibration
gases), precautions may need to be taken to avoid inhalation of,
contact with, or ignition of these gases. In general, these precautions
are as follows.
Always use the correct tubing size for the fittings supplied and
the correct nut / ferrule assembly.
Do not exceed the pressure and flow specifications detailed
below.
Leak check all external pipe work, and recheck periodically.
Leak check inlet system periodically, as defined in this manual.
Before opening up any gas handling part of the system, it may be
necessary to purge the system with a suitable inert or non-
hazardous gas. Gas lines and the exhaust line should be isolated.
Consideration should be given to the possibility and implications
of failure of the isolation mechanism used.
Warning!
It is the responsibility of the instrument user to assess the
potential hazards involved in working on any gas handling parts of
the system.
