Lf. Paradina et La. Pavlova, Microprobe determination of barium, strontium, and scandium impurities in a vitreous substance, J ANALYT CH, 54(1), 1999, pp. 70-74
A set of 22 basalt glasses was prepared For the determination of Ba, Sr, an
d Sc impurities with concentrations of 0.03-7% in vitreous substances. The
glasses were tested for homogeneity and stability under the action of a pro
be and certified. Metrological characteristics of standard reference sample
s were determined according to GOST (State Standard) 8.532-85. Class sample
s were used for the development of a procedure: for the determination of ba
rium, strontium, and scandium in vitreous substances at a level of 7% (RSD
= 3% on average for all elements) to 0.03% for Ba (RSD = 36%), 0.05% for Sr
(RSD = 59%), and 0.01% for Sc (RSD = 69%).
