Spectrochemical Determination of Water in Minerals and Rocks

Volume 21, Number 3 (June 1967) Page 155-156

Quesada, Antonio; Dennen, William H.


The direct determination of water in minerals and rocks using dc-arc emission spectrography is described. A precision of ±8% or better is attained over a concentration range of ∼1%-20% H2O. Electrodes of a special design are used and careful control of absorbed moisture is required.
