For sampling periods of 24 h, the applicable concentration range is 0,003 mg\/m<sup>3<\/sup> to 1 mg\/m<sup>3<\/sup>, and for 72 h it is 0,001 mg\/m<sup>3<\/sup> to 0,33 mg\/m<sup>3<\/sup>.<\/p>\n<p>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.
