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 scan, insert a new sample (or use the same sample, to re-sample the same material),
and select the
Run New Scan
button. The new scan runs, the new absorbance spectrum calculates
(using the previous reference), and the new spectrum plots all with one button click. This action can be
performed repeatedly. Note that the scan name provided on the previous Custom Scan screen
increments with each sample run.
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
