Easy & Precise Retention of a Very Polar Compound 

Acrylamide can be difficult to retain with conventional Reversed Phase Methods due to its polar nature. With this Method however, Retention is readily achievable using a simple, Isocratic Mobile Phase. The overlay of two Chromatograms using two different lots of HPLC  Columns in the Figure below illustrates the Reproducibility and Robustness of this Method.

Note: Acrylamide is a monomer used to synthesize polyacrylamides. It was reported to be present in certain food products in 2002. This has been cause for concern as the monomer form is a known carcinogen and neurotoxin. As such, quantitation of this analyte is of importance in a variety of fields.
