A new Column protection system for Cation-exchange HPLC applications will be unveiled exclusively at Pittcon this year.
The new GARD™ manufactured by Pickering Laboratories is a substantial improvement over the standard packed guards. The new GARD™ adds little pressure, is invisible to the chromatography, and has substantially more capacity for strongly retained compounds that can foul the analytical column.
The new GARD Column Protection System significantly prolongs column life without band spreading or added pressure. We will have a poster at Pittcon demonstrating, by means of a performance comparison for Amino Acid Analysis, that the use of a GARD will protect the analytical column more effectively than traditional guard cartridges, is more cost-effective for the laboratory, is easy to change, and most importantly has zero band spreading.
