The linearity results obtained ˃ 0.9990 for all three impurities. NettetThe slope is an indicator of the % recovery; if the slope is 0.94 then recovery is 94%.Linearity can be accepted if the slope is 1.00 +/- 0.03 and the Y intercept is 0 +/- the within run precision. A general rule of thumb is that a method can be considered linear if there is less than 10% variance between observed and expected values at each level.
