| Summary |
A high rerformance liquid chromakgraphic methcd for determination of sulfamonomethoxine (5MM). Sulfadimethoxine (5DM). and sulf&iuinoxa]ine (SQ) in pcniltry fJs has been deve1o. Using Bro Lee Cl 8 column and acetonitril& 1% acetic acid (1:4) as mobile phase, a gcxid seration and linear calibration cnrves of SMM. SDM and SQ could be obined.
The feels were extni with N-N-dimethylforrnanide. cleaned up on a column of alumina oxide, and elutul with opthnuxn solution, The rooveries of SMM, SDM and SQ for layer feels were %.5%, 95.8% and 97.5% resetively, for broiler feeds were 97%, %.l% and 98.5% xese:tively.
