Polarographic determination of malononitrile.
A procedure is proposed for the determination of malononitrile by differential pulse polarography in methanolic 0.1M tetraethylammonium iodide/0.001M tetramethylammonium hydroxide as the supporting electrolyte. In this medium malononitrile is chemically converted into an electroactive species. With close control of timing of the steps in the procedure the error of the method is +/-1.5% in the c...
متن کاملThe polarographic determination of selenium in urine.
Polarographicdata are presented for the reduction of selenite ion in 3M sulfuric acid, 1M potassium chloride, and 1M ammonia-ammonium chloride. In these first two media two waves are obtained correspondingto the diffusion-controlled reduction of selenite ion to selenium amalgam and the adsorption of selenite ion on the mercury drop, respectively. One wave is obtained in ammonia-ammonium chlorid...
متن کاملDocosahexaenoic Acid (DHA)
Handling & Preparation Instructions This purified fatty acid is liquid at room temperature (oil) and not soluble in water. The product is supplied sterile. It can be solubilized in undiluted serum, ethanol or DMSO. The solubility of Docosahexaenoic acid in ethanol is at least 100 mg/ml. Docosahexaenoic acid has a solubility of 1 mg/ml in a solution of 0.15 M Tris-HCL (pH 8.5). We strongly recom...
متن کاملDocosahexaenoic Acid (DHA) Monograph
Introduction Docosahexaenoic acid (DHA) is an omega-3 fatty acid that falls into the larger category of polyunsaturated fatty acids (PUFAs). Although many chronic conditions are associated with excessive intake of dietary saturated and trans fatty acids (including obesity, insulin resistance, coronary heart disease, and some forms of cancer), research shows omega-3 fatty acids, including DHA, a...
متن کاملPolarographic determination of oxygen tension of whole blood.
The purpose of this study is to establish a procedure for the direct determination of oxygen tension of whole blood that requires a smaller sample and simpler manipulation than methods previously reported (1). A procedure has been worked out for determining dissolved plasma oxygen which proved satisfactory in our investigations. Since the success of the application of the proposed polarographic...
