Standard Test Method for Quantity of Water-Extractable Matter in Membrane Filters

Importancia y uso:

5.1 The presence of water-soluble extractables in membrane filters can create errors in test procedures employing membrane filters. However, these errors can be eliminated or significantly reduced if the quantity of water-soluble extractables of the specific membrane is previously determined. Certain membrane filter uses require specifications of maximum water-soluble extractable levels. This test method is intended to be a rapid test to determine the loss of water-soluble compounds such as plasticizers or wetting agents from filtration membranes. This test method is not designed to predetermine the performance of a filter, but is significant in determining the percent extractables of membranes from different sources and lot variations from a single source.
