Benzene Line
Laboratory Equipment Set
Chemical laboratory equipment set developed for benzene sample preparation used to determine radiocarbon content. Conventional Radiocarbon Dating Method based on liquid scintillation counting (LSC) uses benzene as counting medium.
New lab set (Poland, 2014)
Production Capacity
Benzene Line easily produces 0.1–7.0 g benzene per sample depending on the amount of available datable carbon in sample material. Two benzene synthesis modules highly enhance throughput almost two times or allow production of up to 14 g benzene at once.
Commercial offer includes: shipment of chemical laboratory equipment set, transfer of corresponding technology, lab installation and staff training.
High Temperature Processes
Charring of wood, peat, humic acids, collagen. Production of Li-carbide. Vacuum pyrolysis — direct chemical sorption into a Li alloy of carbonaceous gases produced by controlled thermal destruction of organic materials under vacuum.
Low Temperature Processes
Acetylene production, cryogenic catching and purification. Benzene synthesis using super effective catalyst, cryogenic catching, purification by sulfuric acid treatment and sublimation.
LSC Measurement
Recommended Teflon vials with superior technical performances: high measurement efficiency, low background and low benzene leakages, extreme long durability for optimal C-14 LSC spectrometry in benzene.
The Concept
The Benzene Line concept is to create and use a vacuum line of minimum volume based on: Teflon, Stainless Steel, Titanium and Boron-Silicate Glass as materials. It introduces the technology of Vacuum Pyrolysis and Cryogenic Trapping for controlled transport and transformation of all substances during benzene probe preparation.
Performances are based on simultaneous and independent operation of all subsections of the benzene line. This allows carrying out several processes of sample preparation simultaneously for samples at different stages. It reduces time spent by the operator — attention is required only for the current sub-process, until the moment when the process becomes self-controlled.
Reaction Vessel — The Heart of Benzene Line
- •Covered with hermetic vacuumed and water-cooled head, works at 750–850 °C as described for Vacuum Pyrolysis (Skripkin and Kovaliukh, 1998).
- •Serves to synthesize lithium carbide by performing chemical transformation reactions using carbon from any kind of carbon-containing studied material and lithium metal.
- •Involved in both High T and Low T processes.
