Performance verification
The 5500 Series FTIR spectrometer systems have been thoroughly
tested at the factory, so no alignment steps are required. However, it
is recommended to run the performance test initially to ensure the
instrument is running properly. To run and interpret the
performance test, refer to the MicroLab Software Operation Manual.
The performance test measures the energy level of the instrument
(based on the interferogram voltage or height). A successful test will
be indicated by a green circle at the top of the software screen. You
are now ready to analyze a sample. A yellow or red circle indicates
the instrument is operating outside of the factory defined
parameters. These parameters are listed on the Advanced Features
software page.
NOTE
If the circle at the top of the software screen is yellow or red, contact Agilent
technical support for assistance.
Like any measurement device, it is important to verify that the 5500
Series FTIR instrument is performing properly before using the
system to make critical measurements. The instrument provides both
diagnostic values and performance validation tests to demonstrate
the system’s performance. The diagnostic values provide an easy to
understand, quick assessment of the instrument’s function. If the
instrument is not functioning properly, one of the diagnostic values
will be out of specification. Typically, the instrument will not allow
data collection if the diagnostic values are out of specification.
Performance validation tests are longer, more involved tests that
measure how well the instrument is working. The tests listed under
‘Performance validation’ check the instrument’s sensitivity
(performance), stability and frequency precision (laser calibration).
