Particle Retention Testing of 0.05 to 0.5 Micrometer Membrane Filters
- 更新时间2015-02-10 11:54:00
Innovations in the design and use of membrane fi lters have been a key factor in the quest for better quality electronics, medicines, beverages and biochemicals. As the fi ltered products1 and contaminants2, 3 come under greater scrutiny for both their value and their importance, more attention must be given to meeting and verifying the fi lter specifi cations, especially at the smaller pore sizes. This report discusses some historical approaches to membrane fi lter testing and some new and improved methods for checking retention ratings for 0.05 to 0.5 micrometer (μm) membrane fi lters.
