a/ UCL = Upper control limit. j/ CCB = Continuing calibration blank.<br />
b/ LCL = Lower control limit k/ MSA = Method of st<strong>and</strong>ard addition.<br />
c/ ICV = Initial calibration verification.<br />
d/ CCV = Continuing calibration verification.<br />
e/ %R = Percent recovery.<br />
f/ Exceptions occur when the historical control limits are below or above the maximum/minimum %R value. When this occurs, the historical control limit<br />
takes precedence. Data are qualified as unusable only after the historical control limit is exceeded.<br />
g/ RPD = Relative percent difference.<br />
h/ MB = Method blank.<br />
i/ ICB = Initial calibration blank.<br />
