Valid Analytical Measurement

The VAM Principles

The six VAM principles enable organisations to implement best practice and make valid measurements. They are designed to control all factors that might affect the reliability of analytical results thereby reducing the cost and risk of unreliable measurements.

Principle 1
Analytical measurements should be made to satisfy an agreed requirement.

Principle 2
Analytical measurements should be made using methods and equipment which have been tested to ensure they are fit for purpose.

Principle 3
Staff making analytical measurements should be both qualified and competent to undertake the task.

Principle 4
There should be a regular independent assessment of the technical performance of a laboratory.

Principle 5
Analytical measurements made in one location should be consistent with those elsewhere.

Principle 6
Organisations making analytical measurements should have well defined quality control and quality assurance procedures.
