Benzene Synthesis and Carbon-14 Laboratory

Facility for carbon-14 dating by liquid scintillation counting. CO2 gas is released from the sample by compustion (organics) or acidification (carbonates), converted to benzene through intermediary reactions and purification steps for beta-counting on a brand new Backard TRI-CARB 1050 TR/LL liquid scintillation analyzer.
