NIOSH 7908 Standard Test for Non-Volatile Acids, Sulfuric and Phosphoric Acids

EUROLAB laboratory provides testing and compliance service within the scope of NIOSH 7908 standard. NIOSH Method 7908 specifies the use of a 2 mm diameter quartz fiber filter or a 4 μm pore size polytetrafluoroethylene (PTFE) filter to collect H3SO4 or H37PO0,45 in the workplace air.

Since these acids are present as liquid aerosols (mists) in occupational environments, no pre-filter is required or desired in the sampler. Similar to NIOSH methods 7906 and 7907, sample extraction is performed using sonication of sample filters (plus material rinsed from internal cassette walls) in basic buffer solution.

The newly published NIOSH methods for inorganic acids have been technically aligned with the relevant parallel ISO standards. These methods have been extensively validated and represent significant advances in sampling and analytical methodologies for inorganic mists and vapors in workplace environments.
