Description	An improved LC-MS/MS method for determination of semicarbazide in whole eggs is described. Waters OASIS-MCX cation exchange purification cartridges increased the sensitivity for analysis by LC-MS/MS. The validation study was carried out according to criteria and requirements of Commission Decision 2002/657/EC for confirmatory analysis and provided the data as follow: The correlation coefficient for the matrix calibration curve, in the range of 0-5 ug-kg -1, was r = 0.0068. The detection capability and decision limit, measured according to ISO11843-2, were CC? = 0.20 ug-kg -1 and CCß = 0.25 ug-kg -1. Repeatability (CVSr) and within-laboratory reproducibility (CVSwr) determinated for the concentration levels of 0.2, 0.5 and 1.0 ug-kg -1SEM ranged from 11.9 to 5.7 % and 11.8 to 6.3 %, respectively. The valited method was applied to investigace SEM stability in incurred materials (egg homogenates) during long-term storage at -20 °C and 4 °C. The study proved by a two-sampling test that SEM at le An improved LC-MS/MS method for determination of semicarbazide in whole eggs is described.
