This part of ISO 16000 specifies a determination of formaldehyde in indoor air using a diffusive sampler with solvent desorption and high performance liquid chromatography (HPLC).<\/p>\n

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

\n

NOTE Confirmed samplers with respect to measurement sensitivity and precision can apply to short-term sampling (less than 24 h).<\/p>\n<\/blockquote>\n

The method is suitable for measurements in atmospheres with conventional indoor air relative humidity and for monitoring at air velocities as low as 0,02 m\/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.<\/p>\n

\n

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 ISO 16000 to avoid any impression that ISO favours one model over another.<\/p>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":"
