Present day carbon dating
Here we discuss two microsamples taken from an artwork carrying the date of 1866: a canvas fiber and a paint chip (C analysis.
The initial sample requirement in the method’s early days amounted to tens of grams of material.
Technical advances in general, and especially in the field of gas ion source AMS (5, 6), where mixtures of CO and He gas are introduced straight into the GIS-AMS, have reduced sample requirements to micrograms of material (7), thereby setting a new milestone. Carbon dating has given archeologists a more accurate method by which they can determine the age of ancient artifacts. Libby invented carbon dating for which he received the Nobel Prize in chemistry in 1960.This approach provides relative age information only and thus may fail in proving a forgery.Radiocarbon (C) dating is an attractive alternative, as it delivers absolute ages with a definite time frame for the materials used.

Through the direct coupling of an elemental analyzer (EA) that converts the sample to CO–11) have revolutionized sample requirements and hold great promise to support the research and understanding of cultural heritage materials, where sampling is critical and sample size is very often limited.
