Compared to conventional radiocarbon techniques such as Libby's solid carbon counting, the gas counting method popular in the mid-1950s, or liquid scintillation (LS) counting, AMS permitted the dating of much smaller sized samples with even greater precision.Regardless of the particular 14C technique used, the value of this tool for archaeology has clearly been appreciated.

Radiocarbon dating was the first chronometric technique widely available to archaeologists and was especially useful because it allowed researchers to directly date the panoply of organic remains often found in archaeological sites including artifacts made from bone, shell, wood, and other carbon based materials. Higgs (eds), Science in Archaeology: A survey of progress and research, pp503-512. Fundamentals of bone degradation chemistry: Collagen is not "the way". These contaminants could cause C dates of bone collagen to be either too young or too old, depending on variations of local environment and soil chemistry.To completely remove molecular contaminants is cumbersome and expensive.Sample size If at all possible, please send only the amount required for the radiocarbon dating.
