The steps to take a Quick Scan are:
1. Set the reference by clicking either
Run Reference Scan
or
Use Previous Reference
.
•
Run Reference Scan
causes the spectrometer to scan the reference sample.
•
Use Previous Reference
does not re-scan the reference, but uses reference data from the last
Quick Scan reference.
•
If measuring a liquid sample in a cuvette, then the reference scan is typically taken using an empty
cuvette in the sample holder. This reference scan allows the absorbance of the cuvette material to
be negated when the absorbance of the liquid sample material is calculated.
•
For measurement of solid transmissive materials such as sheet plastic, the sample holder must
remain empty during the reference scan.
2. Users can change the scan name or use the default name. The scan name becomes part of the
resulting scans filenames. These filenames can be downloaded from the DLP NIRscan EVM once
scans are complete.
3. Load the cuvette with the liquid sample or insert the sheet plastic into the sample holder.
