Measuring Samples
34 Agilent MicroLab Software Operation Manual
Collecting a background measurement
It is recommended that the system is configured to collect a
background before every sample.
Before you begin an analysis, the software will automatically collect a
background spectrum when the method is configured as
recommended. The background measurement (with no sample
present) provides a baseline profile of the current system conditions
and enables you to factor out any anomalies occurring in both the
background and sample spectrum.
NOTE
As mentioned above, before collecting a background, ensure that the sample
interface is clean. To clean the sample interface, a suitable solvent such as
methanol, acetone or isopropyl alcohol should be used. See the instrument
operation manual for more detailed information.
To collect a background measurement:
1 On the Home screen, ensure that the appropriate method is
active, and then click START to initialize background sample
analysis.
2 Click Next. A brief check of the sample interface (that is, the
crystal) will occur. Following a successful test, the system gathers
a ‘background’. Background progress is indicated by a status bar.
NOTE
Only click HOME to go back to the main home screen if you wish to start your
analysis over.
