1 – OBJECTIVES

Internal quality control ensures:

• Reliable results
• Technical validation and periodic monitoring of your method (in accordance with SH GTA 04)
• Measurement uncertainty estimations (in accordance with SH GTA 14 guidelines).
• In-house control of your analytical process and performance monitoring.

The principle of internal quality control is simple: detection of analytical errors and validation of your results using samples of known concentrations.

2 – CONTROL MATERIALS

Control samples are CE marked in accordance with European directive 98/79 EC and French law.

Registration for a control scheme includes:

• supply of control specimens
• the acceptable limits defined for your peer group

Control samples are appropriate for the tests performed. The control samples are manufactured by private companies according to our specifications.

The uniformity and stability of control materials has been tested and verified

3 – IQC YEARLY WORKFLOW

The control sample kits ordered are supplied. Information about how the IQC schemes are implemented and take place is available in your user account in the “Documentation” tab.

Target values and acceptable limits are defined for each peer group based on the respective EQA scheme results.
