4.5 Computation and Processing

The following are processed using chromatograms obtained as detection signals. For the

setting procedure, see the LCD Panel Operation Manual, IM 11B03A03-05E.

• Peak processing

• Deviation processing

• Additional processing

• Signal processing

Each processing is outlined below. For details, see the Technical Guide, IM 11B03A03-03E.

4.5.1 Peak Processing

This processing detects peaks from a detector signal and determines the concentrations of

components based on the area or height of each peak. The retention times, peak half-width

and so on are also determined from the detected peaks.

4.5.2 Deviation processing

This processing determines the value obtained by subtracting the sum of the concentra-

tions of components computed by peak processing from the total sum of set concentra-

tions.

4.5.3 Additional processing

There are the following three types of processing in the additional processing:

• Linear computation processing

This processing determines the total sum of the concentrations of each component

computed in the peak processing multiplied by individual coefficients.

• Ratio computation processing

This processing determines the ratio of concentrations of two components obtained

by the peak processing.

• Separation capability processing

This processing determines the separation capability using retention time and peak

half-widths of two adjacent components determined by the peak processing.
