QC charts can be used to check the precision and accuracy of a channel (method) over time. To use this feature, a separate QC chart must be set up for each channel of an analysis and each QC cup. There can be 10 different types of QC cups defined (QC1 - QC10).
The calculated concentration values for the QC cups can be automatically copied into the QC chart. They are collected over a certain period (units, runs, days, weeks, or months). This means that the QC cups can be included in every run, in one run per day, per week or per month. The results of the first period will be used to check for QCs that are out of limit for the next period.
The QC chart is a quick and easy way to track specific QCs for each channel over time.
