IRAffinity-1
IRAffinity-1 has the following measurement modes and they can be selected according to your applications.
Scan mode Description
Spectrum Scan Typical scanning mode.
Background spectrum and sample spectrum are scanned separately using [BKG]
and [Sample] buttons.
Stopping or aborting the scanning is available during scanning.
Continuous Scan Repeats sample scan until "limit" values and these spectra are saved as
independently. This mode should be used with "Auto increment" function.
When the [STOP] button is clicked during scanning, the scanning spectrum is
saved and the remaining scanning is canceled.

Atmosphere Correction
Scan
Automatically applies the atmosphere correction to the measured spectrum
immediately after finishing the scanning. The raw spectrum and corrected
spectrum are stored in a file. Atmosphere correction parameters are set on
[Environment]-[Instruments Preferences]-[Atmosphere Correction].

Automatic
measurement with ASC
Automatically runs samples set on the ASC.
See section 4.6.
Easy Scan Is the program where you execute scanning. When you run the program, you can
do the measurement by operating according to the Displayed messages. You can
also execute peak-picking or printing data by selection.
1. Setting scan parameters
2. Background scan
3. Sample scan
4. Peak detection
5. Saving data
6. Printing out
Evaluation Scan Accumulates only the measured data that shows results that are greater than or
equal to the threshold values are accumulated.
Threshold values are measured to be used for data evaluation measurement.
Once the threshold values have been measured, the parameter values are
automatically set in the [Data Evaluation] section in the [Advanced] tab.
