Benzene line laboratory set
- it is chemical laboratory equipment set which is developed for benzene sample preparation used to determine radiocarbon content.
Conventional Radiocarbon Dating Method based on liquid scintillation counting (LSC) benzene uses benzene as counting medium.
Thus Benzene line easily produces of 0.1-7.0 g benzene per sample depending on amount of available datable Carbon
in sample material. Two benzene synthesis module highly enhance throughput almost two times or allows produce up to 14 g benzene at once in case.
New lab set (Poland, 2014, press to enlarge)
Benzene Line Concept is:
create and use vacuum line of minimum volume based on:
Teflon, Stainless Steel, Titanium and Boron-Silicate Glass as materials;
Introduce Technology of Vacuum Pyrolysis and Cryogenic Trapping for
Controlled Transport and Transformation of all Substances among Benzene Line during of benzene probe preparation.
Performances are based on: simultaneous and independent operation of all subsections of benzene line.
It allows one to carry out several processes of sample preparing simultaneously, but for samples, which stay on their different stages.
It, actually, reduces time spend by operator required for processes to be controlled.
I.e. operator pay attention to current sub-process only, when it required, or, another words until the moment when process become self-controlled.
Commercial offer includes:
Shipment of Chemical Laboratory Equipment Set, Transfer of Corresponding Technology, Lab Installation and Staff Training.
Benzene line consists of: High temperature (High T) and Low temperature
(Low T) processes modules and
Ultimate Teflon vials for C-14 LSC.
High Temperature set serves for:
* Charring of wood, peat, humic acids, collagen etc.
* Production of Li-carbide,
* Use of Vacuum pyrolysis - the direct chemical sorption
into a Li alloy of carbonaceous gases produced by the controlled thermal destruction of organic materials under vacuum conditions.
All above technologies widened applicability of Conventional Carbon Dating for different kind of sample materials.
Reaction vessel is the Heart of Benzene Line.
* It is covered with hermetic vacuumed and water cooled head and it works at 750 - 850 OC as it was described as serving for
Vacuum Pyrolysis at
1998 [
Skripkin and Kovaliukh, 1998].
* It serves to synthetize lithium carbide by performing chemical transformation reactions using C of any kind of carbon containing studied material and lithium metal.
* It is involved in the High T and Low T processes.
Low Temperature set serves for:
* Acetylene production, it's cryogenic catching and purification and by-compacting
* Benzene synthesis using of super effective catalyst, cryogenic catching, purification by sulfuric acid treatment and by sublimation.
General LSC technique:
Recommended Teflon vials
have superior technical performances: high measurement efficiency, low background and low benzene leakages, extreme long durability for optimal C-14 LSC (spectrometry) in benzene.
Thus
using of Teflon vials enables excellent performances for C-14 LS measurement
especially for
small samples of benzene.
Some parts of Benzene Line (benzene synthesizer),
particularly traps could serve as portable C-14 dating equipment which are used to collect carbon dating sample
materials like CO2 and carbonates.
