Instrument Verification
You can run the basic Instrument Verification Checks without changing any settings.
However, you can select further tests and modify the default values for each test.
NOTE:
Before performing any Instrument Verification tests you should remove any sampling
accessory from the beam path. If your instrument does not have an internal filter
wheel, then you will need the slide holder inserted in the beam path.
To run the tests, select
Instrument Checks
and then
Instrument Verification Checks
from the Measurement menu.
Follow the instructions on-screen.
Figure 78 Instrument Verification dialog
The Abscissa Check collects a background spectrum and then collects the spectrum of a
NIR polystyrene reference sample. It then measures the wavenumber at the specified
peaks. If the wavenumber value is within the tolerances defined during setup, the check
passes.
The Ordinate check by default uses a reference card inserted in the slide holder. You
can choose another reference material for the tests, but you will need to change the
default settings.
The Noise Check collects two background spectra and then measures the RMS (%T)
and Peak-to-Peak (%T) noise over a range and reports the baseline Trend. If the values
are within limits defined during setup, the check passes
At the end of the tests a report will be generated (by default) containing the results.
You can run up ASTM Level 0 tests, or tests that comply with the requirements of several
national pharmacopoeias. Refer to the Spectrum on-screen help for more information on
setting up Instrument Verification Checks.
