This application note describes a method for the analysis of impurities in fine chemical octyl-dimethyl-4-aminobenzoate using the Agilent 1290 Infinity LC and ZORBAX RRHT and RRHD 1.8 µm columns
The document describes an analytical method for separating impurities found in a sample of octyl-dimethyl-4-aminobenzoate. It highlights the capabilities of the Agilent 1290 Infinity LC system, specifically its broad power range and advanced optical design in the diode array detector, which allow for high sensitivity monitoring of small impurities.
The system has a conservative setting for approximately 850 bar, which operates within its total 1200-bar capability.
Impurity detection is estimated to be less than 0.01% due to high detector sensitivity and stability.
The analysis uses a ZORBAX StableBond RRHT C18 column with dimensions of 3 mm x 50 mm.
