Vacuum pyrolysis allows to extend variety of sample material applicable Conventional Carbon dating. It simplify and shortened sample processing procedures. Reaction vessel (see scheme, below) is heart of carbide sample preparation in modern benzene line. It allows obtaining of lithium carbide by (1) melting of charcoal (C) and lithium alloy as it is used in conventional procedure, by (2) contacting of CO2 with molten lithium, by (3) contacting of carbonaceous gases produced during pyrolysis of sample material with lithium alloy, and some combination of above based on advantages operation in the one reaction vessel (4).
Benzene line is equipment and technology. It serves to produce benzene sample used for C-14 counting by Liquid Scintillation Counting (LSC) if conventional radiocarbon dating used. Benzene line offered includes set of equipment shipment, laboratory installation and staff training. Benzene line is based on vacuum pyrolysis technology and cryogenic approach for gas transport and conversion. It serves for conversion of datable carbon to: lithium carbide > acetylene > benzene. Technology includes processing, conversion, transport and purification of above mentioned substances. In addition we developed and produced modern Teflon vials for counting of benzene by LSC.
Besides on site we had placed information about application of benzene line as part of conventional radiocarbon dating laboratory, we had described its applicability for dating of archaeological pottery.
