29 de ago. de 2018 · Using a volumetric pipet, transfer 20 mL of the sample to a BOD bottle containing 80 mL of deionized water. If the amount of mercury in the sample is expected to exceed the standards, a smaller aliquot may be taken, and the volume of acid adjusted accordingly. The final volume in NIOSH Manual of Analytical Methods (NMAM), Fourth Edition, 8/15/94
29 de ago. de 2018 · NIOSH Manual of Analytical Methods - 6009.pdf/3. This page needs to be proofread. MERCURY: METHOD 6009, Issue 2, dated 15 August 1994 - Page 3 of 5 the BOD bottle must be 100 mL. To prevent possible loss of mercury during transfer, place the pipet tip below the surface of the liquid in the BOD bottle. CALIBRATION AND QUALITY CONTROL: 10. 11. 12.
7 de may. de 2001 · For concentrations below 20 μg/m 3, the modified NIOSH 6009 method provides an effective way to measure low Hg vapor levels. The modified NIOSH method is simple enough to enable rapid sample turnaround, an important factor in making timely decisions, while conforming to accepted methodologies and QA/QC procedures.
