Description:

The Sample Variable ISTD Amount is only required for a calibration based on a variable Internal Standard (internal or internal/external).

In this case, the column serves in the sample list for entering the amount values of the internal standards used for the different samples. Input is directly in the sample list (via the keyboard or the F8 edit dialog box). Editing the column in the QNT Editor is not possible. Entering the amount values in the peak table is omitted.

Function:

The ISTD Amount parameter is implemented as a multiplication factor in the Amount Calculation Formula and is dimensionless.
