A method for measuring water in organic compounds at the microgram scale, based on quantitative electrolysis in a specially designed apparatus, has been developed.<BR>A quartz sample protector containing 0.30.5 mg of sample weighed in a platinum boat is placed into the drying tube, and is heated at 100150°C under vacuum. Water vapor liberated from the sample is despersed in the diffusion chamber, and is introduced into the electrolytic cell in the stream of helium gas by the new technique of exchanged flow line. The method usually requires only 50 min. per sample, and the accuracy is within about ±0.5 per cent.
