Summary:A micro-method is described for the determination of trace amounts of D 2 O in serum, saliva and urine, requiring 100 of sample. Introduction ___., . ,. rj * · *t j· With the discovery of deuterium, the non-radioactive Several methods have been established for measuring isotope of hydrogen, methods using the dilution of the water compartment and water turnover of the deuterium oxide in the body water compartment have body. Early estimates were made (1, 2) by measuring been well established, the difference between the wet and dry weights of human bodies, indirect methods*used the specific ^«c/ce &Ä ö rv^found that D 2 O permeates biological gravity of the body or the alteration of serum os-membranes as fast as H 2 O (8). Edelman showed that molarity after infusion of hypertonic saune solution 2 hours after application, the concentration of D 2 O /3\ in H 2 O reaches a plateau of identical values in all " ' , , , . body tissues (9). In the 20th century, methods were introduced using tracer substances. Compounds such as urea (4), thio-The toxicity of D 2 O has been widely investigated, urea (5), sulphonanüdes (6), and antipyrine (7) have During short term application, D 2 O volume fractions been used but these methods are inaccurate because of about 0.40 are tolerated without any pathological the tracer substances are eliminated at individual rates effect (10-13). During long term studies, however, thus producing an undefinable individual error in the fertility appears to be impaired if D 2 O concentrations estimation of body water.exceed a volume fraction of 0.20 (14-16).

“…The machine was modified to have a fixed slit width of 2 0 mm at 3-8 ,u. Scanning was from 2880 cm-' to 2400 cm-' (with D20 wavelength at 2520 cm-'), using CaF2 windows and 0 2 mm cell spacers (Fydelor and Rawson, 1964). Samples of the distillate were equilibrated from 10 minutes at 25°C in a water bath.…”
