SPECTRA leading in Applied Spectroscopy: innovation in the continuous monitoring of odorants is the result of entrepreneurial flair and scientific collaboration with the university

SPECTRA solution is the result of AUTOMA‘s wish to offer an alternative to the gas chromatography, traditionally used for odorant measurement in natural gas. Although gas chromatography measurement is accurate and firm, on the other hand it is also rather burdensome in terms of both initial investment and maintenance, with regard to the need for specialised personnel and consumables. It also has requirements that do not allow it to be operated continuously, autonomously and directly in situ. For these reasons, gas chromatography provides a non-continuous monitoring over time, which is ineffective in the early detection of malfunctions and abnormal situations.

SPECTRA, on the other hand, which is based on UV-Visible absorption spectroscopy, is designed for on-site installation and fully automatic operation without human supervision, allowing continuous and timely monitoring of abnormal events occurring in the distribution network.

Based on the positive results obtained in the field since 2014, AUTOMA aimed at and obtained the scientific validation of the measurement method through the publication of an article describing the measurement method behind the SPECTRA solution in the prestigious journal Applied Spectroscopy, a peer-reviewed scientific journal that specialises in spectroscopy and its many applications.

Odorant Monitoring in Natural Gas Pipelines Using Ultraviolet–Visible Spectroscopy

The scientific article “Odorant Monitoring in Natural Gas Pipelines Using Ultraviolet–Visible Spectroscopy” was written thanks to the collaboration of various experts in the sector: Dr. Rossana Galassi (University of Camerino), Dr. Christian Contini (Automa), Engineer Matteo Pucci (Automa), Dr. Ennio Gambi (Polytechnic University of the Marche) and Dr. Gabriele Manca (Institute of Chemistry of Organometallic Compounds, Florence) and is composed of four main sections:

  • Introduction
  • Spectroscopic analysis
  • Computational analysis
  • Experimental section

Since the publication of this paper, it is now clear and definitive that the SPECTRA solution is based on a scientifically rigorous measurement method, and odourant concentration measurements are totally independent of the variability of the concentration of the hydrocarbons that make up almost all natural gas. In addition, the method can also be effectively applied to the measurement of other sulphur compounds and aromatic hydrocarbons.

A result we can be really proud of

This result represents the first scientific acknowledgement of the validity of the SPECTRA measuring system in the field of natural gas odorisation measurement and joins many other successes that over the years have rewarded the continuous research of AUTOMA.
