Pickering Laboratories Analytical HPLC Columns and GARD Column Protection Systems

Pickering Laboratories analytical HPLC columns and guard systems are specifically designed for high-sensitivity chromatographic separations involving post-column derivatization. The product portfolio includes specialized columns for amino acid analysis, carbamate pesticides, glyphosate, aminomethylphosphonic acid (AMPA) and polyamines. Optimized stationary-phase chemistries provide selective retention, reproducible separation and reliable quantification of trace-level compounds in complex sample matrices.

The Pickering Laboratories column range includes dedicated cation-exchange columns for amino acid and glyphosate analysis as well as application-specific columns for carbamate pesticide determination. Each analytical column undergoes controlled packing and chromatographic performance testing to verify the required separation and resolution under specified method conditions. The complementary GARD Column Protection System protects analytical columns against particulate and chemical contamination while minimizing additional band broadening and backpressure.
