RT Journal Article SR Electronic T1 THE DETERMINATION OF CHLORAL HYDRATE, CHLOROFORM, AND RELATED SUBSTANCES IN BLOOD JF Journal of Pharmacology and Experimental Therapeutics JO J Pharmacol Exp Ther FD American Society for Pharmacology and Experimental Therapeutics SP 11 OP 17 VO 74 IS 1 A1 W. LLOYD ADAMS YR 1942 UL http://jpet.aspetjournals.org/content/74/1/11.abstract AB A method for the quantitative determination of chloral hydrate, chloroform and related R-C-X3 compounds in blood is described. The technic, based on the Fugiwara color reaction, avoids the simultaneous preparation of standard solutions by use of the photoelectric colorimeter and calibration curves. The introduction of alcohol to retard color fading makes the method rapid and accurate.
