Abstract: A method for determination of low concentrations of chloramphenicol in urine, feed water, milk and honey was developed. A comparison was carried out between a routinely used analytical method based on solid phase extraction (SPE-C18) for cleaning the extract and the new procedure for the sample preparation using columns based on the molecular imprinted polymers (MIP) principle. The extracts obtained from the MIP clean-up procedure were clean enough for chromatografic analyses. Confirmatory analyses were conducted using GC/MS-NCI after derivatisation (silylation). The described method was fully validated according to CD 2002/657/EC. This method is considerably robust and allows very dirty samples to be processed. The described MIP procedure is very simple and low-time-consuming, and provides high throughput of the samples examined. This could be used for routine screening and confirmatory analyses as well
