Precision on Controls
Quality control materials were analyzed on the 800 series CO-ox module. The
results are presented here.
Precision on aqueous quality control materials was estimated using four 800
systems. One run per instrument was made over a eight day period. Three replicates
of each control level were analyzed in each run.
Table E-43 summarizes the results of the 800 CO-ox module precision on QC
materials.
