The Noise Check collects a 16-accumulation background spectrum, followed by
12 single-accumulation sample scans with an open beam, which are ratioed
against the background spectrum and then averaged. The check then measures
the RMS and Peak to Peak noise over a range and reports the baseline Trend. If
the values are within limits defined during setup, the check passes.
–
The Abscissa Check collects a background spectrum and then collects the
spectrum of a polystyrene reference sample (a polystyrene reference is installed
in the internal filter wheel of the spectrometer). It then measures the
wavenumber at the specified peaks. If the wavenumber value is within the
tolerances defined during setup, the check passes.
At the end of the tests a report containing the results will be displayed. It will be printed if
the Checks Reports option was selected on the Reporting Options dialog. Refer to
on page 80 for more information.
NOTE: Refer to the OilExpress 4 on-screen Help for more information about running System
Checks.
