Disabling Calibration Samples

Use the Calibration tab page to determine which sample shall be used.

It depends on the Calibration Mode which sample Types available (for the sample type, refer to the symbol in the Name column):

Usually standard samples are used for calibration.

Only in the Standard Addition mode, i.e., if you use the Standard Addition method, you can use the sample types Unspiked and Spiked (see Spiked Sample) for calibration.

Click the box in the Enabled column to open the Disable (Enable) Standard xyz dialog box and define whether the respective sample shall be used for calibration purposes. You can exclude the respective calibration sample from calibration either for all peaks and all channels (default setting) or only for the selected peak and/or channel. For more information about how to use this option, refer to the following examples:

The calibration sample was contaminated

Exclude the sample from the calibration. Accept the default setting: Disable the sample for All Peaks and All Channels.

By mistake, too much of a substance was added to the calibration sample

Do not exclude the sample completely from calibration, but disable the calibration for this substance, instead. Click the peak and select Selected Peaks and All Channels in the Disable (Enable) Standard xyz dialog box.

Contamination in the calibration sample that is detected in one channel only

You do not need to exclude the sample completely from calibration. Select the channel that detects the contamination and select All Peaks and Selected Channel in the Disable (Enable) Standard xyz dialog box.

Tip:

The Selected peak and Selected channel options are unavailable in Fixed calibration mode.
