For Removal of Metal Ion Contamination and Restoration of Proper Ion Balance in Glyphosate Analytical Columns and Guards

Glyphosate herbicide analysis by post-column HPLC according to US EPA Method 547 employs a cation-exchange column.  Many polyvalent metal ions which may be present in the sample, especially Iron, will accumulate in the guard or analytical column.  As little as 100 nmole of Ferric ion, for example, will cause serious degradation of column performance; larger amounts can actually cause the glyphosate peak to vanish completely.

Glyphosate RESTORE™ rapidly removes Iron and all other polyvalent metals from the column and guard.  In addition, it preserves the balance of K⁺/H⁺ in the resin, thus avoiding a lengthy re-equilibration.
