Dear Colleagues,
I am currently using the Pickering Labs cation-exchange, HPLC column for
amino acid analysis. The system includes a post-column reactor for
reaction with ninhydrin. The column is 4 x 150mm and the matrix is a
fully sulfonated, polystyrene-divinylbenzene, 5 micron, 100 angstrom
pore size.
I would like information on columns from different manufacturers that
would also work with this system (i do not know who supplies Pickering
Labs) to test as back-up columns.
Thanks for your help,
Joe Sundstrom
Immunex Manufacturing Corp.
