Video about 14 dating liquid scintillation counter:
A number of researchers have participated in the development of 'minivial' technology which has enabled samples of One of the most widely known applications of LSC of 14C is in high precision dating of the radiocarbon timescale for the purposes of calibration. Benzene has been chosen because of its excellent light transmission properties and the high chemical conversion yield of sample C to benzene.
The methods described below are not universally applied in all LSC radiocarbon laboratories, there may be slight variations in some of the procedures between different laboratories and radiocarbon specialists. The purified CO2 is then reacted with molten lithium in a stainless steel or inconel reaction vessel in vacuo: Radon's short half-life of 3.
