Description:

The Sample Variable Weight has two functions. It serves to enter the sample weight but it can also be used as a weight correction factor.

1. Sample Weight: Enter the sample weight to calculate the content - normalized to the basic unit - of a substance in a sample

For example, if the calculated concentrations should always be valid for 1 mg of a sample, enter the actual weight; for example, 124.08. Chromeleon then divides all calculated concentrations by 124.08.

2. Weight Correction Factor (for Standard and Validation samples): If you wish to relate the concentrations to be calculated to a specific concentration, enter the corresponding correction factor as Weight.

If, for example, 4.16 mg were weighed instead of 4.0 mg, you must enter 1.04 (not 4.16!) here. This procedure is called approximate exact weighting.

Function:

The Weight parameter is implemented as a dimensionless multiplication factor or divisor:

1. It is used as factor for calculating the calibration curve (for the formulas, see Theory of Calibration  Evaluation with Various Standard Methods).

2. It is used as divisor for amount calculation (see Formula for Amount Calculation).
