SA-2 Sulfonic acid type containing Amberlite IR-120 WA-2 Carboxylic acid type containing Amberlite IRC-50 Expendable liquid cells for x-ray analysis, molded of rigid polypropylene, are said to be inexpensive enough to discard after a single use. Assembly is by placing V 4 - m i | Mylar on top and pushing a Teflon ring over tapered section of cell until it snaps into a groove. Said to be without seepage in any position. Spax Industries, Inc. P-13
Widely used for particle size control in many industrial processes... for scientific study of fine materials . . . for pretesting dust collector needs . . . for determining the separating efficiency of air cleaners. An S-fraction analysis can be completed at the rate of 15 minutes per fraction by unskilled operators. Fractions are precisely defined and may be retained for accurate study.
