Anions in sodium tetraborate with Metrohm Inline Acidification, Metrohm Inline Matrix Elimination, and Metrohm Inline Calibration
Resumo
Determination of fluoride, chloride, phosphate, and sulfate in sodium tetraborate using anion chromatography with conductivity detection after sequential suppression. Inline acidification is applied to convert tetraborate into boric acid which is not retained on the preconcentration column. Inline calibration minimizes the anion contamination.
