제조사:PALL

Versatile membrane for environmental applications

Low moisture pick-up for weight stability.
Dissolves completely using standard digestion procedures.
Meets a variety of application needs with a selection of disc sizes.
Permits direct infrared measurement of airborne silica dust. Cited in numerous air sampling methods, including NIOSH, MSHA, and AWS methods for airborne silica analysis.
Optimized for air monitoring applications. Contaminants such as silica, dust, welding fumes, hexavalent chromium, and formaldehyde have been effectively collected with this membrane.

learing Procedure - DM Metricel Membrane

Method: Wet (but do not soak) the membrane in a solution of 20% diethyl formamide and 80% ethyl alcohol. Dry 10 to 20 minutes at 77 °C (171 °F). For easy clearing without fiber distortion, place the membrane on an appropriate-sized drop of solution previously applied to a glass slide. The side of the filter with the collected sample should be right-side up (away from the solvent) to prevent loss or disruption of the sample.
