Abstract
IN the course of work on the metabolism of sulphur amino-acids in malnourished infants it was necessary to measure total sulphate concentration in large numbers of urine samples. The urine from these patients is very dilute, so that to obtain accurate results by the classical gravimetric or titrimetric methods it would be necessary to use large volumes. This is inconvenient, since for the oxidation of organic sulphur the urines have to be digested with concentrated acid. By precipitating with barium chloride containing radioactive barium, and measuring the radioactivity in the precipitate, the estimation could be made on 0.1–0.5 ml. urine.
