Primesep B2

by SIELC

SIELC Technologies provides 4 types of different B-type columns with positively charged functional groups.

Primesep B2 is a weak basic column. It also has carboxilic acidic functional groups. At pH of the mobile phase below 5 the acidic groups are not ionized and B2 column surface becomes positively charged. This dual chemistry offers extended pH range from 0.5 to 7, suitable for the ammonium acetate and ammonium formate buffered mobile phases.
