# Recovery for calibration solutions

in Informatics

Hi all,

in one of our analysis we calculate the samples by a linear regression using 3 calibration solutions (50%, 100% and 150%). For the calibration there are two acceptance criteria specified in the analytical procedure.

1) R NLT 0.99

2) Recovery of the individual calibration solutions calculated via the linear regression 98-102%

In the calibration curve window (review) I found the both values "X Value" and "Calc. Value". Does Empower calculate the recovery (Calc. Value * 100% / X Value) for each injection of the calibration solutions or must I creat a CF?

Thanks in advance

The % Deviation may be more useful to you and is a measure of theoretical versus actual amount.
