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.
