A pyrolysis furnace heats a rock sample under programmed temperature conditions. Using a flame ionization detector (FID), three peaks are quantitatively recorded - S₀, S₁, S₂ and the Tmax parameter (or five peaks - S₀, S₁, S₂₁, S₂₂, S₂₃). Carbon dioxide formed during pyrolysis is detected by an infrared detector as an S₃ peak (in this case, organic and mineral CO - S3CO and S3′CO, as well as organic and mineral CO₂ - S3 and S3′ are recorded separately). The residual carbon in the sample after pyrolysis is burned in an oxidation furnace and detected by an IR detector as residual organic carbon S₄ and residual mineral carbon S₅. Based on the data obtained, the content of total organic carbon (TOC) and mineral carbon (MinC) in the sample is calculated.
The maximum operating temperature of pyrolysis and oxidation furnaces is 850 °C, which makes it possible to accurately determine the Tmax value at higher temperatures.
All parameters of pressure and gas flow in gas lines are automatically measured, displayed and adjusted (optional, upon customer request).
The operating status of the instrument and analysis results can be transmitted via Bluetooth or a network.
In addition to the standard analytical parameters S₀, S₁, S₂, S₄ and Tmax, the device also determines S₃ and S₅, and also calculates TOC (total organic carbon) and MinC (mineral carbon) content.
Optional: automatic sampler for at least 50 positions (at customer's request).
The ability to set custom temperature programs (up to 10 stages of programmable heating), which allows you to analyze various types of samples - source rocks, reservoir rocks, coals, oil shale, as well as experiments on the kinetics of hydrocarbon generation.
