Processing Spectra

To process your data in Spectrum software, ensure that the spectra you wish to process are

selected in the Data Explorer and then select the appropriate option from the Process menu

(Figure 37).

Figure 39 Process menu in Spectrum

When the spectra have been processed, if the process generated new spectra they will be

added to the Data Explorer with _n appended to the name to create a unique Sample ID.

Spectra created by processing are not saved automatically. For more information, see

Saving

spectra

on page 71.

NOTE:

For full details of each process, refer to the Spectrum on-screen Help.

Spectral correction

Several processes in Spectrum enable you to adjust your spectra after data collection. For

example, there are commands for the conversions of ordinate units, such as: Absorbance,

Transmittance, Kubelka–Munk and Convert X.
