The round-robin test is offered alternatively with and without sampling. Participants may choose whether they wish to perform sampling for aldehydes themselves, or to have the sample carriers supplied to them.
Analysis should be conducted by HPLC according to IFA Folder No. 6045  or DIN ISO 16000-3  respectively.
At the dynamic test gas stream at the IFA up to thirteen participants can carry out parallel sampling.
Participants will receive detailed information on the round-robin test, a description of the apparatus, and the connections for the sampling devices in particular, in good time.
The production of samples for aldehydes is conducted at the dynamic test gas stream of the IFA.
The laboratories may choose from two different sample carriers (Waters Sep-Pak DNPH-Cartridge or Supelco LPDNPH S10 Cartridge). Each participant receives a sample kit comprising:
