Microdetermination of oxygen, carbon and water in inorganic materials using a carrier-gas technique

A description is given of the accurate determination of small quantities of oxygen, carbon and water in inorganic compounds. Oxygen and carbon are determined by a conductimetric technique and water by a coulometric technique. The limits of detection of the different methods are: 0.1 microg of oxygen, 0.1 microg of carbon and 0.03 microg of water. This is accomplished by taking special care to obtain a low blank and by using stable instruments. A suggestion is made for the simultaneous determination of water and hydrogen.
