MEASUREMENT METHOD The measurement method is based on capillary zone electrophoresis with indirect UV detection at thewavelength of 254 or 267 nm. MEASUREMENT RANGE The measurement range for the components is 0.01-40% for the sample weight of 100 mg. The determination is not hindered by the presence of other inorganic cations (Ba， Li， Sr， Mn， Fe) in theconcentrations that are typical for this type of samples. EQUIPMENT AND REAGENTS The CAPEL capillary electrophoresis system is used in measurements. Data acquisition， collection，processing and output are performed using a personal computer running under WINDOWSXP/7/8/10operating system with installed dedicated software package ELFORUN. Lumex Instruments set， order No 0300001912.
