Calculation of replicate mean
This calculation is carried out for calibrators according to the following equation:
The calculation of concentration of replicate r and the mean determined by linear
interpolation are used for the Replicate Deviation check.
Result calculation checks
Replicate Deviation check This check is carried out for calibrators only. It examines the scattering of replicates
of calibrators.
The following equation is applied to each replicate:
The > Repl Dev flag is displayed if a result exceeds the preset deviation.

Replicate results of calibrators.
Linear interpolation is applied for non-linear calibration modes.
Linear regression is applied for linear calibration modes. A
differentiation based on the underlaying calibration mode is not
required.
