The graphical representation shows the absorbance spectrum of the material, with absorbance units (AU)
on the y-axis and sampled wavelength on the x-axis.
1. To run another Quick Scan, insert a new sample in the sample holder and select the
Run New Scan
button. The new scan is taken, the new absorbance spectrum is calculated (using the previous
reference), and the new spectrum re-plots to the screen all with a single click. This action can be
performed repeatedly. The filename provided on the previous Quick Scan screen is incremented with
each sample run so that sample data files can be distinguished from each other.
2. To save the spectrum data to a local machine, click the
Download Spectrum Data
button. This action
prompts the user to open the .csv file in excel (if available on the users machine) or to save the file
locally. The file format imports into excel as shown in
