HPLC Separation of Glyphosate Reaction Intermediates and Impurities

March 3, 2010

View Application

Glyphosate and intermediates/impurities of production are separated on an Obelisc N HILIC/ion-exchange column by a combination of HILIC and ion-exchange mechanism. Method can be used in analysis of glyphosate, iminodiacetic acid, (N-phosphonomethyl)-imminodiacetic acid, diethanolamine and related impurities in reaction mixtures, waste and ground waters. Detection techniques are LC/MS, ELSD, CAD and UV.

Condition
Column	Obelisc N, 4.6×150 mm, 5 µm, 100A
Mobile Phase	MeCN/H2O
Buffer	Ammonium Formate
Flow Rate	1.0 ml/min
Detection	ELSD

Description
Class of Compounds	Herbicide, Hydrophilic, Ionizable
Analyzing Compounds	Glyphosate, IDA, PMIDA, DEA

Application Column

Obelisc N

SIELC has developed the Obelisc™ columns, which are mixed-mode and utilize Liquid Separation Cell technology (LiSC™). These cost-effective columns are the first of their kind to be commercially available and can replace multiple HPLC columns, including reversed-phase (RP), AQ-type reversed-phase, polar-embedded group RP columns, normal-phase, cation-exchange, anion-exchange, ion-exclusion, and HILIC (Hydrophilic Interaction Liquid Chromatography) columns. By controlling just three orthogonal method parameters - buffer concentration, buffer pH, and organic modifier concentration - users can adjust the column properties with pinpoint precision to separate complex mixtures.

Select options

DEA (Diethanolamine)
Glyphosate
IDA (Iminodiacetic acid)
PMIDA (Phosphonomethyliminodiacetic acid)

ELSD Detection

SIELC Technologies usually develops more than one method for each compound. Therefore, this particular method may not be the best available method from our portfolio for your specific application.

HPLC Separation of Glyphosate Production Intermediates

January 13, 2010

View Application

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

Application Column

Primesep 100

The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers.
