The following table shows all the Qumran-related samples that were tested by Zurich (Z), Tucson (T) and Libby (L).The column headed "14C Age" provides a raw age before 1950 for each sample tested.C atoms in the sample would greatly enhance the sensitivity, and some unsuccessful attempts were made in this direction using conventional mass spectrometry. This technique has allowed the measurement of radiocarbon in samples of much less than a milligram, or over a thousand times less material than is needed from the older counting methods.Since 1947, scientists have reckoned the ages of many old objects by measuring the amounts of radioactive carbon they contain.
