摘要: Abstract A new absorption-catalytic method of sample preparation for AMS 14C analysis has been designed. The semi-automatic graphitization equipment consists catalytic combustion, selective absorption/desorption CO2 and zones. Sample combustion followed by separation takes less than 30 min that allows plenty samples to be processed in a short time. average conversion graphite turned out 75%. Achieved value background induced contamination with contemporary carbon is about 1.2 pMC. proposed reproducible according results the OX-I OX-II oxalic acid standards measured from 2015 2018 successfully used dating lake sediments. agree data other laboratories. penetration model aerosol particles inhaled at low dose mice studied means designed method.
