5.16.13<Compound Table Wizard 3/5> Specify a quantitative calculation method and a calibration curve type. Set the necessary parameters such as
Quantitative Method, Calculated by, Curve Fit Type, and Units.
5.16.14<Compound Table Wizard 4/5> Specify a method for identifying peaks.
After completing the settings for the identification method, click on the
[Next] button.
5.16.15<Compound Table Wizard 5/5>Finally, Enter the component name of the peak, Type parameters to “Target”. For the internal standard method, specify only the Type of the internal standard substance as “ISTD” and enter the same number in the [ISTD group] of the internal standard peak and the peaks that are calculated using that peak. For Conc. 1, 2, and 3, enter the level-1 concentration, level-2 concentration, and level-3

concentration of each compound included in the standard sample. (The
“Level” of the sample to be analyzed will be specified for each sample in the Batch Table.
5.16.16After finishing the settings in the <Compound Table Wizard>, click on the
[View] button located in the upper right corner of the “Compound Table” to establish the edited “Compound Table”. If you want to cancel the edited
“Compound Table”, select [Table Edit] - [Cancel Edit] from the menu before clicking on the [View] button.
5.16.17Save the analytical parameters set in the <LC Data Analysis> window as a method file.
5.16.18Click on the [Apply to Method] icon on the [LC/PDA Data] page of the
Assistant Bar.
5.16.19
The dialog box will be opened prompting you to enter the name of the method file to be saved. The original method file name is entered as the default setting. To apply the settings in the <LC Data Analysis> window to the original method file, click the [OK] button to overwrite it. The dialog box will be opened prompting you to select whether or not to apply the parameters for the method (see the following window). Click on the
[OK] button. The above operations will overwrite the original method file with the changed data analysis parameters.
