  • ASTM D6552 - 06(2011) standard practice for controlling and characterizing errors in weighing collected aerosols

    The weighing of collected aerosol is one of the most common and purportedly simple analytical procedures in both occupational and environmental atmospheric monitoring (for example, Test Method D4532 or D4096). Problems with measurement accuracy occur when the amount of material collected is small, owing both to balance inaccuracy and variation in the weight of that part of the sampling medium ...

  • Straightforward determination of anhydrosugars in aerosols

    Metrohm presents a new method for the sensitive and robust routine determination of the «smoke markers» levoglucosan, mannosan and galactosan in aerosols. The method couples ion chromatography with a highly sensitive pulsed amperometric detector (IC-PAD) and provides a simple and less expensive alternative to GC/MS. As such, it facilitates research into the effects of biomass burning aerosols on ...

  • ASTM D6561 - 06(2011) standard test method for determination of aerosol monomeric and oligomeric hexamethylene diisocyanate (HDl) in air with (Methoxy-2–phenyl-1) Piperazine (MOPIP) in the workplace

    HDI is mostly used in the preparation of paints. For the last ten years, the use of isocyanates and their industrial needs have been in constant growth. Diisocyanates and polyisocyanates are irritants to skin, eyes, and mucous membranes. They are recognized to cause respiratory allergic sensitization, asthmatic bronchitis, and acute respiratory intoxication (3-6). The American Conference of ...
