FAQ

QuestionAnswer
What is the difference between pore size and pore size distribution?Whereas pore size is a measure of the diameter of the largest pore, pore size distribution is a measure of the range of pore sizes. The range of pore sizes can be normally distributed, and the spread can be quite narrow (e.g. the ratio of largest to smallest may be less than 2). On the other hand, pore size distribution can be very heterogeneous. In the case of large spreads and heterogeneity, the pore size will be far less predictive of flow rate (either filtration or capillary) than it will be for a membrane with a narrow pore size distribution. It is important to note that the pore size corresponding to the bubble point is not at the middle of the distribution, but is the largest pore.
Which filter do you recommend for EPA Method 1311 (TCLP)?The filters cited by the EPA in the TCLP ("Toxicity Characteristic Leaching Procedure") Method are our AP40 filters. These filters are made of glass fiber and contain no resin binders that could contaminate your analysis. If you are testing for volatiles your filter holder will usually take a 90mm diameter filter (Catalog # AP4009000). If you are testing for non-volatiles, semi-volatiles or metals your filter holder will usually take a 142mm diameter filter (Catalog # AP4014250).
