Data from a validation of an HPLC method for isoflavones in legumes is used to show the errors in recovery when a check sample is presented to the instrument using a calibration which satisfies the linearity tests. It is recommended that both y - and relative x -residuals are inspected. It...
Linearity is one of the most important performance characteristics of an instrumental analytical method when linear response is assumed; thus it is an interesting parameter to be evaluated in validation studies [1]. After adjusting a linear function to a set of calibration data, points are expected...
