Rescue archaeological research at the Church of St. Wenceslav in Plasy, Czech Republic, revealed a burial ground. Radiocarbon dating of the remains (teeth, bones) was used to explore the history of the pre-monastic settlement. Due to a low quality of the analysed samples, a standard acid-base-acid sequence was followed by ultrafiltration to purify gelatinized fraction. The yields, dates and stable isotope ratios of non-ultrafiltered and ultrafiltered samples are compared and the impact of the ultrafiltration on the data interpretation is discussed.
