Aldehydes

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 self-conditioned sample carriers supplied to them.

Analysis should be conducted by HPLC according to IFA Folder No. 6045 [1].

1. Round-robin test with sampling

   At the dynamic test gas stream at the IFA up to twelve participants can carry out parallel sampling.

   When:
   11/12 September 2012
   13/14 September 2012

   Where: Institut für Arbeitsschutz der Deutschen Gesetzlichen Unfallversicherung (IFA)
   Alte Heerstraße 111
   53757 Sankt Augustin
   Germany
   

   Concentration range: The concentration for Formaldehyde will lie in the range between 0.01 and 1 mg/m³, for Acetaldehyde, Propionaldehyde, Acrolein and Butyraldehyde in the range between 0.1 and 3 mg/m³.
   Duration: 2 hours
   Number of test series: 3
   

   Accomodations: Hotels at Sankt Augustin
   Participants will receive a description of the apparatus, and the connections for the sampling devices in particular, in advance.

2. Round-robin test without sampling

   The production of samples for volatile inorganic acids is conducted in parallel to the round-robin test with sampling. The sample carriers must be sent by the participants to the IFA prior to the round-robin test. Only personal air samplers are used at the IFA. The sample carrier should not generate a back pressure exceeding 5.0 kPa under the specified conditions. Where internally fabricated sample carriers are used, please supply an adapter (GL14/GL25 threaded connection) for the test gas stream. The samples are loaded by IFA before being returned to the participants.

   Each participant receives a sample kit comprising:

   • Three loaded sample carriers, and
   • Two unloaded sample carriers for blank value adjustment.
