HPLC Separation of Glyphosate Production Intermediates

January 13, 2010


Glyphosate is a broad spectrum herbicide used to kill weeds. It is the most used herbicide. Glyphosate is an aminophosphonic analogue of the natural amino acid glycine. Glyphosate and its intermediates are very polar ionic compounds derived from glycine. Neither of intermediates can be retained on traditional reversed-phase columns. Two methods for glyphosate intermediates were developed on Primesep B, Primesep B2 and Primesep 100 columns.

Condition
Column Primesep B, Primesep B2, Primesep 100,  4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN/H2O
Buffer TFA, H2SO4
Flow Rate 1.0 ml/min
Detection ELSD

 

Description
Class of Compounds
  Insecticide, Herbicide, Fungicide,  Hydrophobic, Ionizable
Analyzing Compounds Glyphosate, PMIDAA, IDA

HPLC Separation of Ethanolamines

December 5, 2006

Primesep 100 separates ethanolamines (monoethanolamine, diethanolamine, and triethanolamine) by a combination of cation-exchange, hydrophobic, and polar interactions. The separation uses a mobile phase mixture of water, acetonitrile (MeCN, ACN) and trifluoroacetic acid (TFA) with evaporative light scattering detection (ELSD).
