    maximum volume: 30 Liters
    maximum flow rate: 2.0 L/min (Ceiling)
    current analytical method: Inductively Coupled Argon Plasma; ICP/DCP-AES
    method reference: 2 (OSHA ID-125G)
    sampling and analytical error: 0.12
    method classification:Fully Validated
    note: Analytical method does not distinguish between dust and fume. When analysis of a compound is requested, an elemental analysis is performed and reported as the compound. If confirmation of Vanadium Pentoxide is necessary use the following sampling procedure:
  • sampling media: Tared Low Ash Polyvinyl Chloride (LAPVC) filter 5 microns with 10 mm Nylon Cyclone
    maximum volume: 816 Liters   
    minimum volume:
    408 Liters   
    maximum flow rate:
    1.7 L/min
    current analytical method: X-ray Diffraction, XRD; and X-ray Fluorescence, XRF
    method reference: 2 (OSHA ID-185)
    method classification: Fully Validated
    note: Submit as a separate sample.
