Microliner thermodestruction technology

Microliner technology.

  • This is highly effective technology for processing of small amount of datable Carbon.
  • It is applicable for any kind of sample material.
  • It is followed by hydrolysis system for microsamples.
  • It is included in processing of small samples.
  • It is simple in use.

Capsule technology in Benzene Line

Capsule technology.

It was designed for direct obtaining of acetylene from very small samples of organic matter or carbonates. It allows producing benzene from very small quantities of acetylene (as low as 0.05 g) with the overall chemical yield higher than 92% for organic samples and higher than 96% for carbonates.

Recent progress in development and application of new performances Teflon vials for radiocarbon LS counting.

As it was stated (Robert M Kalin and Austin Long, 1989) traditional Teflon vials may have limitation like they are time consuming and may require individual calibration in series and benzene leakage limited. Glass vials (A. G. HOGG, 1992) will cover wide range of benzene volume measured (0.3 Ml to 10 Ml), when 10 Ml vials are most applicable for precise measurement of radiocarbon and when 0.3 Ml vials are suitable to provide accurate results with adequate precision for many applications, for samples containing 120-240 mg of carbon. Our developments (Michael Buzinny and Vadim Skripkin) create of two parts 0.8 Ml Teflon vial with different holder which have quite good performances described above. Now we offer most recently developed (Skripkin, unpublished) super performance Teflon vials are long durability, simple in use with different volumes: 0.8 Ml, 1.5 Ml, 2.5 Ml, 4.0 Ml 7.0 Ml with extra Low benzene leakage.

In addition application of underground laboratory (Wolfango Plastino and Lauri Kaihola) can significantly decrease counting background.

Benzene line application

Benzene line is used to produce benzene as counting media for C-14 counting in benzene with Liquid Scintillation (LS) spectrometer i.e. Conventional Radiocarbon Analyze. Benzene line application as a part of Conventional Radiocarbon Analyze is:

  • Radiocarbon dating i.e. dating of the past;
  • Estimation of impact of nuclear installation (NPP) on the environment;
  • Estimation of bio-based percentage in production and raw materials.
  • Estimation of bio-based percentage of Bio-based in fuel (bio-diesel and waste fuel).
