This part of ISO16000 specifies a determination of formaldehyde in indoor air using a diffusive sampler with solvent desorption and high performance liquid chromatography (HPLC).

The test method is applicable to the measurement of formaldehyde1) in indoor air over the range from 0,001mg/m3 to 1,0mg/m3 for a sampling period of between 24h and 72h. For sampling periods of 24h, the applicable concentration range is 0,003mg/m3 to 1mg/m3, and for 72h it is 0,001mg/m3 to 0,33mg/m3.

NOTE Confirmed samplers with respect to measurement sensitivity and precision can apply to short-term sampling (less than 24h).

The method is suitable for measurements in atmospheres with conventional indoor air relative humidity and for monitoring at air velocities as low as 0,02m/s. The chromatographic step in the method is designed to eliminate potential interferences, including those due to the presence of other carbonyl compounds. The sampling method gives a time-weighted average result.

NOTE There are several diffusive samplers with various designs and shapes commercially available. They are all based on the reaction of 2,4-dinitrophenylhydrazine with formaldehyde. They are not specifically described in this part of ISO16000 to avoid any impression that ISO favours one model over another.
