Run Precision

Run precision requires at least five runs. Run precision criterion is met when the sample vol-
umes calculated for the four most recent previous runs fall within the specified error band for
the current run's sample volume. The error band is a specified percentage of the nominal vol-
ume of the sample chamber (1, 10, 100, or 350 cm
