Analyzing Samples
24 Agilent Cary 630 FTIR Spectrometer User’s Guide
NOTE
To ensure accuracy of the measurement, it is recommended that the system is
configured in the software to collect a background spectrum before every sample
is analyzed. This provides a baseline profile of the system conditions with no
sample loaded on the instrument. By collecting a background automatically
before each sample measurement, negative effects of changes in the
environment can be avoided.
This section covers specific instructions for how to analyze a sample
with each sampling accessory, as well as how to interchange
accessories.
Interchanging Sampling Accessories
To switch between different sampling accessories:
1 Before attempting to change the sampling accessory, ensure that
the Cary 630 FTIR system is on a solid surface with the accessory
facing towards you.
2 To remove an installed sampling accessory, push the retaining
lever located on the right side of the instrument to the side. While
pushing the lever to the side, slide the accessory upwards to
remove it from the main Cary 630 FTIR unit.
