Silver Membrane Filters  

Silver Metal Filter Membranes are pure metallic silver (99.97% pure silver) and are available with particle retention ratings of 0.45 or 0.8 microns. Silver metal membranes are used in a variety of filtration applications, and their ability to withstand extreme chemical and thermal stress makes them ideal for applications involving aggressive fluids and/or high temperatures.
 

  • 99.97% pure silver
  • High temperature resistance
  • High chemical resistance
  • Economical - can be cleaned & reused
  • Smooth surface for particle capture and easy observation

Typical Applications 
The smooth surface, surface capture and particle retention characteristics of the silver membrane make it especially effective for the collection and identification of many types of airborne contaminants as well as those found in all types of critical liquid systems. Silver membranes are frequently referenced in the "NIOSH Manual of Analytical Methods." Representative applications include: 
 

  • Collection and analysis of coke oven emissions, where the silver membrane is used directly to collect coal tar pitch volatiles; (See Bibliography and NIOSH Manual of Analytical Methods.)
  • Collection and analysis of polyaromatic hydrocarbons using microanalysis techniques on the gases evaporated from the membrane.
  • Analysis of airborne silica in foundries, glass plants, quarries, mines, ceramic manufacturing, etc. requires collection of an air sample on a polymeric membrane, then transfer of the sample to a silver membrane for X-ray diffraction; (See Bibliography and OSHA).
  • Collection and analysis of airborne asbestos fibers by X-ray diffraction.
  • Collection and analysis of carbon and carbon black.
  • Collection and analysis of fly ash directly from smoke stacks where high temperature stability of the membrane is required.
