Proficiency testing scheme for aldehydes

The proficiency testing (PT) scheme is offered alternatively with and without own sampling. Participants may choose whether they wish to perform sampling for aldehydes themselves, or to have the sample carriers supplied to them [1].

Three test gas mixtures with different individual substance concentrations are offered. A test gas mixture consists of three to four aldehydes. The following aldehydes are used: formaldehyde, acetaldehyde, propionaldehyde and butyraldehyde. The concentration for formaldehyde will lie in the range between 0.03 and 1 mg/m³, for acetaldehyde, propionaldehyde and butyraldehyde in the range between 0.1 and 3 mg/m³ each.

Analysis should be conducted by HPLC according to IFA Folder No. 6045 [2] or DIN ISO 16000-3 [3] respectively.
