by SIELC
SIELC Technologies provides 4 types of different B-type columns with positively charged functional groups.
Primesep B4 column originally developed for direct plasma analysis, became very useful for other anion-exchange/reverse phase applications. It has extended pH range from 1.5 to 7 and offers similar properties as Primesep B2 column but the column has no carboxilic groups and remains positively charged throughout the working pH range.
