Gravimetric Isotherm Rig
The CSIRO Gravimetric Isotherm Rig V3.0 can measure isotherms from as low as 1.0 m3/tonne (1.0 cc/g) with a measurement precision of 0.25 m3/tonne (0.25 cc/g). Although this instrument has been designed primarily to characterise gas adsorption in unconventional petroleum reservoirs, such as shales and coals, it can also be used for gas adsorption in other areas of engineering. The rig was designed and built in-house in our laboratories in Melbourne, Australia.
Main benefits of the Gravimetric Isotherm Rig V3.0
- Larger sample sizes – 4 x 110cc sample cell volume, invaluable in heterogeneous materials
- Faster – Run times of less than 24 hours can be readily achieved
- Cleaner – No oil bath
- Cheaper – With 90% of the process fully automated, operators can move on to other tasks
- Easier – The gravimetric method does not rely on a gas tight system, although preferred. If a minor leak occurs, the results are not compromised; the operator does not need to waste valuable time chasing minor leaks
