SEMI C82 - Test Method for Particle Removal Performance of Liquid Filter Rated 20 to 50 nm With Liquid-Borne Particle Counter -

Abstract

This Document is to provide a standard of monodispersed gold nanoparticle (GNP) challenge test for liquid filter rated 20 to 50 nm using optical liquid-borne particle counter.

　

This Document covers a monodispersed GNP challenge test method for 20 to 50 nm rated liquid filter.

　

This Document defines a test condition for monodispersed GNP challenge test.

　

The following areas are to be addressed in this Document:

• The test condition such as fluid, flow rate, pressure, GNP concentration, ligand concentration, membrane treatment etc.
• The type of filter evaluated.
• The type of gold nanoparticle (GNP) (reference material).
• The method of membrane treatment prior to the test for decreasing the adsorbing effect.
• The description of the test result.
