A Colorimetric Procedure for the Measurement of Dimethyl Sulfide in Water, Wort, and Beer
A colorimetric method is presented for the quanti tat ive determination of dimethyl sulfide (DMS) in water, wort, and beer. The method is based on the formation of a complex between DMS and sodium nitroprusside. The DMS-sodium nitroprusside complex which is formed under alkaline conditions turns pink when the solution is acidified. The pink complex has an absorption maximum at 520 nm. Details o...

متن کاملSignificance of Spiral Organisms Found, after Treatment, in Late Human and Experimental Syphilis.
In previous publications (Collart, Borel, and Durel, 1962a, b), we have described the methods which we have used in a long series of experiments in late syphilis in rabbits and have announced our results. This study in animals led us to carry out the same investigations in humans with late syphilis and the preliminary results were published in the same year (Collart, Borel, and Durel, 1962b, c)...
