Rock-Eval 6
The apparatus is equipped with two ovens: pyrolytic and oxidation. The analysis uses a ground rock sample (less than 0.2 mm) of 50-100 mg, which is placed in a special metal crucible. Analysis in a pyrolytic oven (under a nitrogen atmosphere) can be carried out in the temperature range of 80-850oC with a wide possibility of programming the temperature cycle in terms of: the initial temperature and its holding time, the rate of temperature ramping (from 0.1 to 50oC/min) and the final temperature and its holding time. Released hydrocarbons (HC) are detected on a flame ionization detector (FID), and CO2 and CO are measured on an infrared (IR) detector.
Analysis in an oxidation oven (in an air atmosphere) can be carried out in the temperature range of 100-850oC with a wide range of programmable temperature cycles in terms of: initial temperature and holding time, rate of temperature ramping (from 0.1 to 50oC/min) and final temperature and holding time. The products of combustion and decomposition - CO and CO2 are transferred to the IR detector for quantification. Other oxidation products are not determined.

The RE analysis is dedicated to assess the source rock potential of oil and gas generating rocks. It enables determining TOC and MINC content and hydrocarbon potential of source rocks and genetic type and degree of thermal maturity of organic matter, indicating saturated zones of migrating hydrocarbons and determining the amount and fractional composition of petrochemical products in soils. RE analysis can be used to analyze soils, sediments and non-volatile petrochemical products.
