From this information, students will be able to identify the caffeine peak in the sample’s graph. Students will calculate the area under the caffeine peak. Using the calculated area and a calibration ...

But radiocarbon dating using the most up-to-date version of the radiocarbon “calibration curve” for this period – which accounts for how concentrations of 14 C in the atmosphere vary over time – still ...

By plotting the fluorescence lifetime of the rotor versus known viscosity values of methanol and glycerol mixtures, the researchers created a calibration graph. They were then able to use this ...

This much anticipated new calibration curve, a set of data points used to convert radiocarbon-dating results into calendar years, is highlighted in a special August issue of Radiocarbon.
