Abstract A new method is reported for determining total shortchain fatty acids in stool water and urine. The method uses ion-exchange resins to remove interfering substances, and determines these acids by direct titration. Lactic acid, if present, is determined along with the short-chain (C1-C6) organic acids. Interferences such as carbonate, phosphate, creatinine, bile acids, and uric acid are removed by the ion-exchange treatment. Values obtained by this simplified technique correlate very well with those by gas-chromatographic analyses of the same sample, and the method represents a significant improvement over the Van Slyke technique.

Those samples which swell rapidly when exposed to water are, at best, difficult to section for transmission electron microscopy. Some materials literally burst out of the embedding block with the first pass by the knife, and even the most rapid cutting cycle produces sections of limited value. Many ion exchange resins swell in water; some undergo irreversible structural changes when dried. We developed our embedding procedure to handle this type of sample, but it should be applicable to many materials that present similar sectioning difficulties.The purpose of our embedding procedure is to build up a cross-linking network throughout the sample, while it is in a water swollen state. Our procedure was suggested to us by the work of Rosenberg, where he mentioned the formation of a tridimensional structure by the polymerization of the GMA biproduct, triglycol dimethacrylate.
