HPLC Method for Analysis of Selenious Acid on Newcrom BH Column
July 11, 2017
Selenious Acid is used in protecting and changing the color of steel, most often in weaponry. It is highly toxic in excessive quantities, and if ingested, it could lead to death. The Acid is also capable of penetrating the skin and can produce acute poisonings. Newcrom BH, a reverse-phase column, contains embedded basic ionizable groups and can retain Selenious Acid. The method is UV compatible and can be used as a general approach for analyzing similar compounds.

Application Column
Newcrom BH
The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.
