Quality Policy

The objective of passam QA program is to manufacture effective diffusive samplers and to provide analytical data that is reliable, amenable to statistical evaluation, technically sound and defensible and is provided in a cost effective and efficient manner.

The emphases are

Long-term comparability of results
internal procedures and recording enables constistent data over time
Treacability
the analytical chain is based on certified reference materials and treacable to national bodies
Transparent evaluation of measuring uncertainties
The whole analytical chain is regularly verificated by using controlled test-atmopheres. Uncertainties are assessed according to GUM
