Proactive disclosure Print version   | |  Radiocarbon Dating del C-13s Analyses The Geological Survey of Canada Radiocarbon Dating Laboratory ceased operation at the end of 2005. This site will be maintained to provide reference information on the samples dated during the 45 years of operation of the GSC laboratory from 1960 to 2005.
Prior to 1975 some del C-13s were determined by the GSC Geochronology Section and some by Teledyne Isotopes, Westwood, New Jersey. Between 1975 and 1985 del C-13s were determined by the Department of Earth Sciences, University of Waterloo, Waterloo, Ontario, or by Waterloo Isotope Analysts, Inc., Kitchener, Ontario (R.J. Drimmie, chief analyst) using the same equipment as at the University of Waterloo. In 1985 the analyses were done by OCGC Stable Isotope Facility, University of Ottawa, until 1987 when the analyses were carried out by the GSC Stable Isotopes Laboratory. From 1993 to 2005 the del C-13Cs have been analysed by OCGC Stable Isotope Facility, University of Ottawa. Natural del C-13 Sample Fractionation
