SKC Silver Membrane Filters
Specified for X-ray Diffraction Analysis

SKC silver membrane filters are made of 99.97% pure metallic silver in a controlled environment. The many desirable properties of silver membranes make them suitable for a wide range of applications. The orientation of a silver membrane filter is important. Each side of the silver membrane filter is different. One side appears shinier than the other side does. Use the shinier side for scanning electron microscopy (SEM) and the duller of the two sides for all other filtration applications and analytical work, including X-ray diffraction. A smooth surface provides for superior collection of particulates with a typical aerosol retention of 99.99% (0.3-µm DOP at 3 L/min through 10 cm2).

Chemically resistant to the following categories of chemicals: Alcohols Fuels Hydrocarbons Natural and synthetic oils Alkalis Cryogenics Photoresists Ether Propellants Oxidizers Halogenated hydrocarbons Esters Most organics and acids

A typical filter will have a rough side and a shiny side. The shiny side is easier to read under a microscope, therefore, expose the shiny side to the air for microscopic analysis. The rough side holds dust more effectively; expose the rough side for gravimetric analysis.
