Application
Sodium tetraborate decahydrate may be used in the following studies: • Modified carbazole method for the quantitive determination of hexuronic acids. • Quantitative estimation of aminoglycoside antibiotics (dihydrostreptomycin and streptomycin) by capillary electrophoresis coupled with UV detection. • To compose the buffer along with cholic acid sodium solution (pH 9.2) for micellar electrokinetic chromatographic (MEKC) quantification of pesticides.
