  • HPLC Method for Analysis of m-Xylylenediamine (MXDA) on BIST™ B+ Column

    Separation type: Bridge Ion Separation Technology, or BIST™ by SIELC Technologies m-Xylylenediamine (MXDA) is a popular curing agent used on epoxy resins. Using SIELC’s newly introduced BIST™ method, MXDA, which protonates in water, can be retained on a positively-charged anion-exchange BIST™ B column. There are two keys to this retention method: 1) a multi-charged, negative […]
