Pickering Laboratories columns and guards are intended for specific applications that require post-column derivatization. This technology guarantees detection of certain classes of compounds at very low concentrations—amino acids, carbamate pesticides and polyamines, for example.
Each column is packed and tested to separate the target compounds according to Pickering’s chromatographic quality control standards and published analytical method. The following acceptance criteria apply to all of Pickering’s columns:
With guard column installed, produce a specified chromatogram of the compounds in a standard test mixture.
Separate the compounds in the established order, with specified resolution of critical pairs.
Operate within the specified range of back pressure.
Be free of contaminating material which can cause baseline artifacts.

Cation – Exchange Columns and Guards Catalog Information
GARDTM Column Protection System
The new GARD™ significantly prolongs column life without band spreading or added pressure.
Lithium Columns
Pickering Laboratories specialize in manufacturing of cation-exchange columns for amino acid analysis.
Sodium Columns
Ion-exchange chromatography followed by post-column derivatization has been a method of choice for amino acid analysis for many years.
Glyphosate Herbicide Analysis Columns
Our cation-exchange Glyphosate column is designed and tested for analysis of Glyphosate.
ALKION Columns™
The stationary phase in the ALKION™ column is a rigid, non-porous polymeric phase that is surface sulfonated.
Carbamate Pesticides Columns
Our carbamate columns are guaranteed to produce the separation of carbamate residues.
Mycotox™ Columns
Aflatoxins are naturally occurring toxins belonginh to the class Mycotoxins.
Polyether Antibiotics
Polyether antibiotics are best quantified using HPLC with post-column derivatization.
