Reproducibility

The standard deviation or relative standard deviation calculated from among-laboratory data.

Expressed as the reproducibility standard deviation (SD R

); or % reproducibility relative standard

deviation (% RSD R ).

Recovery

The fraction or percentage of spiked analyte that is recovered when the test sample is analyzed

using the entire method.

5. Method Performance Requirements :

See table 2 and 3.

6. System suitability tests and/or analytical quality control:

Suitable methods will include blank check samples, and check standards at the lowest point and

midrange point of the analytical range.
