Spectrophotometric Determination of Microgram Quantities of Copper in Biologic Materials.
A procedurefor the determination of microgramquantities of copper in biologicmaterial is described. The sample is wet-ashed with a nitric acid-perchloric acid mixture. The copper is extracted from an alkaline solutionof the ash with a solutionof diphenylcarbazide in benzene. Absorbanceof the red complex is read at 540 m1&. The copperin as little as0.5 ml. of serum can be determined and the meth...
متن کاملDetermination of Microgram Quantities of Inorganic Boron in Mammalian Specimens.
A method is presented for estimation of inorganic boron in mammalian tissues, blood, cerebrospinal fluid, and urine. The procedure is simple and rapid, qualifying it particularly to meet needs in clinical chemistry. The mammalian tissues are first enzymatically digested and extracted; then the deproteinized extract is allowed to react with quinalizarin in concentrated sulfuric acid. The intensi...
متن کاملThe Simultaneous Determination of Partial Specific Volumes and Molecular Weights with Microgram Quantities*78
A method is described for the simultaneous measurement of partial specific volumes and molecular weights of proteins and other substances by sedimentation equilibrium experiments in Hz0 and D20 (or D2018) solutions. In effect, the method is a differential sedimentation equilibrium technique based upon the change produced in the equilibrium concentration distribution when the density of the solu...

متن کاملSpectrophotometric determination of sulfur dioxide in air, using thymol blue.
A simple and sensitive spectrophotometric method was developed for the determination of trace amounts of sulfur dioxide. The method is based on the reaction of SO2 with a known excess of ICI as the oxidant. The unreacted ICI iodinates thymol blue under acidic conditions. The lambdamax of thymol blue is at 545 nm under acidic conditions, and on lodination lambdamax shifts to 430 nm. This shift r...
