Making Dissolved Gas Analysis Easy

The Polyarc is the next evolution of flame ionization detection (FID). The Polyarc converts the FID into a truly universal carbon detector using proprietary catalytic reactions that convert organic molecules to methane immediately prior to detection.

The FID has two main challenges: lack of uniform response and low response to certain compounds. The Polyarc enhances the FID to solve these challenges by giving FID a uniform response to nearly all organic molecules. The result is more accurate data, improved productivity, lab efficiencies, and the ability to detect more compounds.

Salient Features

  • Same GC. Same Software.
  • Better Data Universal carbon response provides better data quality, increased throughput, and more economical.
  • Give your FID a universal and uniform carbon response with a 7-order of magnitude linear range analysis.
  • Reduces the need to perform time-consuming calibrations by creating a uniform detector response.
  • Compliant with EPA Method 25 (25A/25C), ASTM D3612 and meets or exceeds the performance specifications for all methanizer applications/ methods (ASTM, UOP, EPA, FDA, EN, ISO and more).
The Polyarc System


  • Dissolved gas analysis (DGA) is an important method for the determination of pending or current faults within a power transformer. Specifically, as a transformer ages, the oil that insulates and cools components can begin to degrade. The analysis of several dissolved gases (H2, N2, O2, CO, CO2, C2H2, C2H4, C2H6, C3H8, C3H6, C4H8) can give early indicators of faults and transformer stability.
  • The Polyarc system has been a game-changing device for more than 80% of TOGA/DGA testing labs in the US. It is both fully compliant with ASTM method D3612 and is also easy to install and operate, meaning it can be incorporated without changing conventional methods.
  • A conventional methanizer converts CO and CO2 to methane, allowing low level FID detection of CO and CO2 converts all compounds to methane, allowing not only for the detection of CO and CO2, but also millions of other organic compounds.
  • This results in zero laboratory downtime and planned GC maintenance at designated intervals, increasing laboratory productivity and profitability.
