Field Geoscan laboratory and field instruments

The FIELD GEOSCAN is the field-deployable version of Vinci’s well-established Rock-Eval instrument designed for the geochemical analysis of rock samples.

• It operates with a single oven that performs both pyrolysis and oxidation cycles.
• The system allows the determination of key hydrocarbon and kerogen parameters such as:
• S1
• S2
• Tpeak
• Tmax
• These parameters are obtained through high-temperature pyrolysis.
• Analytical programs can be configured with single or multiple heating ramps, typically ranging from about 40°C (or ambient +20°C) up to 850°C.
• Samples are introduced individually into the oven using a loading piston.

The system can also be optionally upgraded to measure:

• S3
• S4
• S5
• TIC (Total Inorganic Carbon)
• TOC (Total Organic Carbon)
• This enables a more comprehensive characterization of the sample’s carbon content and thermal properties.
• All data are automatically processed using the dedicated GEOWORKS geochemistry software.

• Pyrolysis oven temperature: selectable from 40°C to 850°C
• Number of samples: 1
• Temperature rates: adjustable from 1 up to 50°C/min, with steps of 1°C/min
• 5 possible ramps

Detector types:

• FID for hydrocarbons
• Infrared cell for CO and CO2 (optional)

Carrier gases:

• Nitrogen (pyrolysis)
• Pure zero air (oxidation and FID)
• Hydrogen for FID
• Compressed air for oven cooling
