| titleOfInvention | Method for detecting sulfonamide residue in eel by pressurized capillary electrochromatography |
| abstract | The invention relates to a method for detecting sulfonamide residues in eel by pressurized capillary electrochromatography, which is characterized in that the method comprises the following steps: extracting a sample by ethyl acetate, purifying the sample by a HLB solid-phase extraction column, and filtering the sample by a 0.22-micron filter membrane, performing analysis by pressurized capillary electrochromatography, performing detection at 270 nm with an ultraviolet detector by using a capillary electrochromatographic column with reversed-phase bonds and C18 as fillers as a detection column, wherein the mobile phase is acetonitrile and sodium dihydrogen phosphate (5 mmol/L, pH 6.0) with a ratio of 30:70 (V/V). The invention performs pretreatment of the sample by using a classic sample treatment method of liquid-liquid extraction combined with solid-phase extraction, and effectively reduces the content of impurities in fish flesh tissue and matrix interference; the capillary electrochromatography is adopted for analysis and detection, which has less organic reagent consumption; with the application of an external voltage, the retention time of 5 sulfonamides is reduced; the sensitivity is improved; 5 sulfonamides are separated and detected simultaneously; the method of the invention not only meets routine detection of eel sulfonamide residual quantities, but also is applicable to the detection of sulfonamides in other aquatic product samples. |
