Should archaeologists care about 14C inter-comparisons? Why? A summary report on SIRI [PDF]
, 2017 Radiocarbon (14C) dating is used widely in many projects as a basis for the creation and testing of chronological constructs. 14C measurements are by their nature complex and the degree of sample pretreatment varies considerably depending on the material.

Isotope (14C and 13C) analysis of deep peat CO2 using a passive sampling technique [PDF]
, 2009 We developed and tested a new method to collect CO<sub>2</sub> from the surface to deep layers of a peatland for radiocarbon analysis. The method comprises two components: i) a probe equipped with a hydrophobic filter that allows entry of ...
