Precision on manual aqueous quality control materials was estimated using a
minimum of 3 Rapidlab 1260 systems. Controls were measured over a minimum
of 10 days.
Precision on the aqueous quality control materials in the AutomaticQC module
was estimated using a minimum of 3 Rapidlab 1260 systems over a minimum of
10 days. AutomaticQC is automatically scheduled to run (single sample)
independently 3 times per day.
The following tables summarize the results of the Rapidlab 1260 system precision
for manual QC and AutomaticQC.
