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 .
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  or DIN ISO 16000-3  respectively.
A large-scale dynamic test gas stream can be found at the IFA. It is suitable for parallel sampling by up to 25 participants.
The registration for the PT schemes with own sampling is valid for only one person per participating company or institution. If you would like to participate with more than one person, please contact us in advance.
Participants will receive detailed information on the PT scheme, a description of the apparatus, and the connections for the sampling devices in particular, in good time.
|Covid-19 regulations: |
The PT schemes with own sampling are carried out according to the Covid 19 hygiene and behavioural specifications of the DGUV in force at the time of performance. You will be informed in advance about the regulations to be observed.
Loading of the sample carriers for aldehydes is conducted at the dynamic test gas stream of the IFA.
The participants can choose between two different sample carriers:
Waters Sep-Pak DNPH-Cartridge (Prod. No. WAT047205) or
Each participant receives a sample kit comprising:
