The proficiency testing (PT) scheme is offered with or 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.

1 Proficiency testing scheme with own sampling

A large-scale dynamic test gas stream can be found at the IFA. It is suitable for parallel sampling by up to 25 participants.

  • When:
    1st date for the PT: 17/18th November 2026
    2nd date for the PT: 18/19th November 2026
  • Where:
    Institut für Arbeitsschutz der Deutschen Gesetzlichen Unfallversicherung (IFA)
    Alte Heerstr. 111
    53757 Sankt Augustin
    Germany
  • Concentration range:
    formaldehyde: 0.03 - 1 mg/m³
    acetaldehyde, butyraldehyde, propionaldehyde: 0.1 - 3 mg/m³ each
  • Number of test series: 3
  • Duration per test series: 2 hours plus preparation time and run-in period
  • Accommodations: Hotels in Sankt Augustin (PDF, 45 kB, non-accessible)

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.


2 Proficiency testing scheme without own sampling

Loading of the sample carriers for aldehydes is conducted at the dynamic test gas stream of the IFA.

  • Choice of sample carriers (one type):
    1. Waters Sep-Pak DNPH-Cartridge (Prod. No. WAT047205),
    2. Supelco LPDNPH S10 Cartridge (Prod. No. 21014) or
    3. Supelco DNPH S10L Cartridge (Prod. No. 505361-U)
  • Date: November 2026

Each participant will receive a sample kit comprising:

  • three loaded sample carriers (of the selected type), and
  • two unloaded sample carriers (of the same type) for blank value adjustment.

The samples will be loaded with a standard sample air volume of 40 L.
