Abstract
This paper shows that the depth water of Lake Baikal is useful as a reference material in intra- and interlaboratory quality control of chemical analysis for low-mineralized natural waters. The results of numerous determinations of major ion contents in Baikal water, as well as pH and electrical conductance values, are considered. Our data on the concentrations of the main ions in the reference material based on the depth Baikal water and the results of intercalibration with this reference material obtained from 14 hydrochemical laboratories are presented.
