What is this ISO 16000 ‑ 39 - A mines in indoor air about? ISO 16000 ‑ 39 discusses indoor air. ISO 16000 ‑ 39 along with ISO 16000 ‑ 38 , specifies the measurement method for determining the mass concentration of primary, secondary, and tertiary aliphatic and aromatic amines in indoor air using accumulated sampling and high-performance liquid chromatography (HPLC) coupled with tandem mass spectrometry (MS-MS) or high-resolution mass spectrometry (HRMS). The analytical procedure is covered by ISO 16000 ‑ 39 . The sampling procedure and the manufacturing of the samplers are covered by ISO 16000 ‑ 38 . ISO 16000 ‑ 39 describes specifications for the chromatography and the mass spectroscopy for the amines. Measurement results are expressed in μg/m3. The range of application of ISO 16000 ‑ 39 concerning the concentrations of amines in indoor air depends on the linear range of the calibration line and hence on the gas sample volume (here: from 5 l up to 100 l), the eluate volume (from 1 ml up to 5 ml), the injection volume (from 1 μl up to 10 μl) and the sensitivity of the analytical equipment (e.g., linear range from 2 pg up to 2 ng amine). Who is ISO 16000 ‑ 39 - Amines in indoor air for ? ISO 16000 ‑ 39 on the determination of amines in indoor air is useful for: Real estate developers Architects ...
