Glyphosate Guard column to be replaced by New GARD

In an effort to offer superior products, Pickering Laboratories will replace the Glyphosate Guard column (PN 1953020) with the new GARD column protection system <link to GARD abstract>. The Glyphosate Guard Column (PN 1953020) will no longer be available starting Januray 1, 2013. The new GARD prolongs column life without additional back pressure or band spreading.
