Glyphosate Herbicide Analysis Columns

Overview

img-ccg-introGlyphosate Herbicide Analysis Columns

Pickering Laboratories cation-exchange Glyphosate column is designed and tested for analysis of Glyphosate and its primary metabolite Aminomethylphosphonic acid (AMPA). This short, isocratic method provides separation of the peaks of interest. Reproducible performance is guaranteed run-to-run and column-to-column.

 

Post-column Conditions for Glyphosate Analysis:

Reagent 1: Oxidizing reagent—100 μL of 5 % Sodium
                  Hypochlorite in 950 mL of GA116
Reagent 2: 100 mg of OPA, 2 g Thiofluor™ in 950 mL of GA104
Reactor 1: 36 °C, 0.5 mL
Reactor 2: ambient. 0.1 mL
Reagents flow rate: 0.3 mL/min

Detection:

Fluorometer: λex 330 nm, λem 465 nm

GARD™

img-ccg-intro2GARD™ Column Protection System

The new GARD™ uses a proprietary material to prevent matrix compounds from passing through (and thereby protecting the analytical column), but allows the analytes of interest to pass unimpeded through the GARD™ and onto the analytical column.

The new GARD™ significantly prolongs column life without band spreading or added pressure. We demonstrated, by means of a performance comparison for Amino Acid Analysis, that the use of a GARD™ will effectively protect the analytical column, will be more cost-effective for the laboratory, is easy to change, is universal to cation-exchange applications, and most importantly has zero band spreading.

With the new GARD™ Column protection system from Pickering Laboratories the same cation-exchange GARD™ can be used for nearly all cation-exchange applications.
