Operation
7.1 Introduction
The CMS5000 can be programmed to operate uninterrupted or at timed intervals,
either through remote operation or through the front panel. Following a method run,
analysis results can be uploaded onto an FTP site allowing for data review at an
off-site location. The results are also stored directly onto the hard drive of the
CMS5000 unit.
The CMS5000 will commence sampling the air sample or the headspace above the
water sample at the beginning of the method run. The results will be shown on the
front panel during the run. If accessing data from a remote location, the results will
be available immediately following the method run.
7.2 Default Methods
Default methods are included with the CMS5000. The CMS5000 Ck Std method
verifies that the retention time and the response of the internal calibration standard
is within range. The CMS5000 Water Purge method detects specifically selected
VOCs during water monitoring. The CMS5000 Air Purge method detects
specifically selected VOCs during air monitoring.
7.3 System Calibration Standard
A toluene filled permeation tube is used to calibrate the CMS5000 system and has
a life span of approximately eight years. The software will use this calibration to
automatically compensate for normal fluctuations in detector sensitivity.
7.4 Operating the CMS5000 using the Front Panel
1 Touch ESC until the CMS5000 Main Menu is displayed. See Figure 7-1 .
