Glyphosate RESTORE 250mL

Description

Product Description: Glyphosate RESTORE 250mL

Glyphosate RESTORE 250mL is strongly acidic and can displace tenaciously bound Fe+3 from the ion-exchange medium. In addition, it preserves the balance of K+ and H+ in the resin, thus avoiding a lengthy re-equilibration.

Glyphosate herbicide analysis by post-column derivatization and 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 nanomole of ferric ion, for example, will cause serious degradation of column performance; larger amounts can actually cause the glyphosate peak to vanish completely.

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

Note: The use of a guard column containing the same cation resin as the column is strongly recommended, as the guard will normally trap all of the metal ions, and will be the only column requiring the use of RESTORE. Tests in our laboratory have demonstrated that the guard can accumulate sufficient iron to completely absorb glyphosate without bleeding Fe+3 into the analytical column.

The traditional metal removal process using EDTA requires a long treatment time, and an even longer re-equilibration period. Glyphosate RESTORE rapidly removes iron, nickel, aluminum, and chromium from the column and guard. The column and guard are ready to use after only a very brief re-equilibration with the K200 (potassium phosphate) eluant.
