It also provides a safe combustion vessel for samples with high volatile content such as nutshell and fresh wood.
Above Right: It can be interfaced with a, large combustion vessel capable of processing up to 4 kg sediments, and can be interfaced with an acidification apparatus for carbonate dating including up to 5 gallon water for DIC.
If you want to dry your samples, heating at 90°C to 100°C for 4-24 hours is recommended.
Sending wet or frozen samples for radiocarbon dating is fine.
Natural 14C can be used in numerous applications, of which radiocarbon dating, with the possibility for dating back to about 50000 years, is among the best-known and most practiced applications.
Radiocarbon dating is based on the property that the activity concentration of 14C in dead tissues can be used to calculate the time that has elapsed since death occurred. More details Reporting time At present (March 2017) it takes ca 2-3 months (excluding periods when the laboratory is closed for holidays) from the arrival of a sample until we report the result to the customer.
Read More Published on November 3, 2014 Please be advised that our Miami radiocarbon lab and London forwarding facility will be closed during these periods (all dates inclusive): * Miami lab (USA) - November 27-30, 2014; December 24-28, 2014; and on January 1, 2015 * ... This is possible since all living organisms contain nearly the same proportion of radioactive carbon in their carbon stores and since, upon the death of the organism, the carbon which survives decomposition continuously loses 14C by its radioactive decay. This applies to normal samples, and the time varies depending on the type of material.Reporting time for fast handling is maximum 6 weeks but normally 3-4 weeks.Above Left: It can be interfaced with a molecular sieve to trap CO catalyst column is activated at 250ºC under vacuum before trimerization and benzene is extracted at 80 ºC under vacuum for LSC analysis.Above Left: Wallack 1220 Quantulus™ Ultra Low Level Liquid Scintillation spectrometer.All samples submitted for dating must be accompanied by a sample description form.
