Performance Evaluation Program

Test samples are sent by CALA twice per year. The laboratory has participated in accredited external performance evaluation programs since 1994.

The principals and methodology applied to CALA accredited methods are applied to all analysis performed in our laboratories. Rigorous quality control procedures are employed. The use of certified laboratory control standards (LCS), analysis of preparation duplicates and blanks, repeat recalibration and use of separate source calibration check standards ensures that the data we provide is of the highest quality and is completely reproducible.

The ASU's CALA accreditation document is shown below:

CALA Accreditation

CALA is an organisation dedicated to achieving the highest possible levels of quality data within Canadian environmental laboratories. Laboratories which are CALA accredited go through regular confirmatory testing. The methods relevant to individual labs, their locations, and their performance evaluations are listed in the CALA homepage.

The ASU has been an accredited laboratory since 1995.
