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.
