Quality control is a reliable way of ensuring analyser performance as everything from inlet to waste is controlled in this process and assessed across lot changes by means of QC datalogs, QC statistics and Levey-Jennings plots.
QC measurements are automatically evaluated against calibration status, analyser malfunctions and QC control ranges and given a status accordingly to provide the operator with an overall analyser parameter status.
If a QC result is outside the control range, the analyser can repeat the QC measurement automatically attempting to remedy the situation. The parameter can also be automatically locked out requiring operator intervention.
