Synthesis of the Stationary Phase IS-Anionic (Internal Surface-Anionic) for Extraction of Ochratoxin A and B from Samples of Beers

A new IS-anionic stationary phase was synthesized to make on-line extraction of the ochratoxin A and B from samples of beer for HPLC. The propyltriethylammonium chloride stationary phase was characterized affecting it’s elementary determination and RI specter, respectively. Evaluation of the IS-anio...

description A new IS-anionic stationary phase was synthesized to make on-line extraction of the ochratoxin A and B from samples of beer for HPLC. The propyltriethylammonium chloride stationary phase was characterized affecting it’s elementary determination and RI specter, respectively. Evaluation of the IS-anionic column for the extraction and quantification of OTA and OTB in beer has shown that the column is suitable for efficient extraction (recovery >76.5%) and precise analysis. The detection limits for OTA and OTB were 0.03 and 0.07 μgL(−1), respectively. The range of detector linearity was 0.03 at 20 μgL(−1).
