Benzene line

This Equipment is developed to produce benzene used to determine Radiocarbon content.

Benzene is used as measured media for conventional radiocarbon dating based on liquid scintillation counting (LSC). Thus depending on available datable Carbon benzene line produces of 0.1-6.0 g benzene per sample.

OUR CONCEPT IS:

Creation of minimum volume Vacuo Benzene Line based on Teflon, Stainless Steel, Titanium and Boron-Silicate Glass as materials; Introduce Technology of VacuumPyrolysis and Cryogenic Trapping for Controlled Transfer and Transport line of All Substances in the Benzene Line during probe preparation.

Commercial offer includes:
- Chemical Laboratory Set,
- Chemical Technique,
- Equipment Setup and
- Staff Training.

Benzene line consists of subsets used for
High and Low temperature processes and
Ultimate vials for C-14 LSC.

High Temperature set serves for:

- Charring of wood, peat, humic acids, collagen etc. Li-carbide production,
- Vacuum pyrolysis - the direct chemisorption into a Li alloy of carbonaceous gases produced by the controlled thermo-destruction of organic materials under vacuum conditions. - Above technology widened application of conventional C-14 analyse equipment for different kind of materials.

Reaction vessel is the Heart of Benzene Line.

Reaction vessel is included in the high and low T processes. It serves to synthetize lithium carbide by performing of chemical transformation reactions using C of any kind of carbon containing studied material and lithium metal. It is covered with hermetic vacuumed and water cooled head and it works at 750 - 850 oC as it was described serving for Vacuum Pyrolysis at 1998 [ Skripkin and Kovaliukh, 1998].

Low Temperature Set serves for:

- Acetylene production and catching by freezing,
- Acetylene purification,
- Benzene synthesis and catching by freezing,
- It uses super effective catalyst,
- Benzene purification by acid treatment and sublimation.

General LSC technique
We recommend Teflon vials of extreme long durability for optimal C-14 LSC (spectrometry) in benzene, which have excellent technical performances: extreme measurement efficiency, low background and low benzene leakages. Thus application of Teflon flasks especially for small samples of benzene enables excellent performances for C-14 LS measurement: high counting efficiency, low background, negligible leakage and extreme durability.

Benzene Line Apparatus is Chemical Laboratory Equipment set for benzene production to be used as counted media for C-14 LS Counting. Radiocarbon Analyse Machine. Setting up a radiocarbon laboratory and personel training.

Some parts of Benzene Line traps could serve as portable C-14 dating equipment which are used to collect carbon dating sample materials like CO₂ and carbonates.
