HPLC Method for Analysis of Fluoroacetic acid, Difluoroacetic acid and Trifluoroacetic acid on BIST A+ Column
Separation type: Bridge Ion Separation Technology, or BIST™ by SIELC Technologies Fluoroacetic acid is a toxic metabolite of some drugs that contain fluorine and is a common ingredient in pesticide production. Difluoroacetic acid (DFA) is typically used as a difluoromethylating reagent. Trifluoroacetic acid (TFA) is a popular reagent in organic syntheses and is a popular […]

HPLC Method for Analysis of Inorganic anions on BIST™A+ Column
Separation type: Bridge Ion Separation Technology, or BIST™ by SIELC Technologies Using SIELC’s newly introduced BIST™ method, a mixture of many different inorganic anions can be separated on a negatively-charged, cation-exchange BIST™ A column, contrary to conventional chromatographic wisdom. There are two keys to this retention method: 1) a multi-charged, positive buffer, such as N,N,N’,N’-Tetramethyl-1,3-propanediamine […]
