Standard Test Method for Quantity of Water-Extractable Matter in Membrane Filters
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the gravimetric determination of the water-extractable material present in membrane filters and is applicable over the complete concentration range of extractables.
1.2 The analyst should be aware that adequate collaborative data for precision and bias statements as required by Practice D2777 is not provided. See Section 11 for details.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Significance and Use
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.
