Proficiency testing (PT) is offered solely with own sampling. Participants perform sampling for organic solvents themselves at the dynamic test gas stream at the IFA[1].

The concentrations to be measured depend on the occupational limit values of the solvents. They will lie within the range of 1/100 to two times the AGW1 value.

The PT scheme consists of three runs with different substances and different concentrations in the test gas. The test gas will contain up to ten different organic solvents.

Examples of substance selection – Proficiency testing for organic solvents

Substance group Substances
Alkanes [1] cyclohexane, n-decane, n-heptane, n-hexane, methylcyclohexane, n-nonane, n-octane
Alcohols 2-butanol, i-butanol, n-butanol, cyclohexanol, ethanol, 1-propanol, 2-propanol
Aromates [2] cumene, ethylbenzene, propylbenzene, toluene, 1,2,3-trimethylbenzene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, o-/m-/p-xylene
Esters [3, 4] n-butyl acetate, i-butyl acetate, ethyl acetate, methyl acetate, methyl methacrylate, n-propyl acetate, i-propyl acetate
Ethers [4] 2-butoxyethanol, 2-butoxyethyl acetate, 1,4-dioxane, 2-methoxy-1-methylethyl acetate, 1-methoxy-2-propanol, tetrahydrofuran

The substances can be analysed by means of the analysis methods according to IFA Folder No. 7732 [2], 7733 [3], 7322 [4] resp. 7569 [5].

1 Proficiency testing with 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.

2 Proficiency testing without own sampling

The proficiency testing Organic Solvents will be offered 2022 only with own sampling.

1 The German acronym AGW stands for Arbeitsplatzgrenzwert (Occupational Exposure Limit value – OEL). For carcinogenic substances and substances without AGW the database GESTIS - International limit values for chemical agents ( is used.

Covid-19 regulations:

Only one person per participating company is allowed to attend; this person must be able to prove that he/she has been fully vaccinated or that he/she has recovered from an infection (not more than ½ year ago).

Please also inform yourself again before your visit about the visit regulations of the DGUV that will then apply.
