SINTEF ChLab is used to characterize solids used in a CCS context. In most cases the solids are characterized in its ponderous form.
Solid and liquid state Nuclear Magnetic Resonance Spectroscopy (NMR)
For solid state NMR analyses a Bruker Avance III 500 MHz wide bore spectrometer equipped with four probes for different applications is available: Two MAS probes for solid samples, 3.2 and 4 mm. The 4 mm probe is useable up to about 300 ºC and has a wide tuning range covering NMR frequencies for all elements. One high resolution probe for tissue samples,
gels, and other liquid-solid dual phase samples. One flow probe for NMR studies of gases reacting with solids (in-situ). Useable up to 350ºC at atmospheric pressure. In addition, a Bruker Avance III 400 MHz spectrometer is available for liquid samples.
In-situ powder X-ray diffraction (XRD)
A PANalytical Empyrean X-ray powder diffractometer equipped with an Anton Paar XRK 900 in situ cell can be used to get mechanistic information on sorbent function and possible degradation during operation. Using the in-situ cell, measurements can be performed up to 900°C and 10 bars. A variety of gas compositions can be mixed by an automated gas feeding and mixing system (H2, CO2, CO, CH4, N2, H2O, and misc.). Additionally, the in situ cell can also be connected to a vacuum pump for measurements under vacuum. For experiments under gas flow, the gas will pass through the sample and the effluent gas can be analysed by IR or MS.
In-situ Diffuse Reflectance Infrared Spectroscopy (DRIFTS)
DRIFTS characterization can be carried out in various pre-mixed gas streams at temperatures from -80°C to 800°C. Such data typically gives information about chemical reactions taking place and the formation of surface groups within the pores of a solid. Information obtained from such experiments is often complementary to the information obtained from solid state NMR and powder XRD, but together the three methods may give a complete picture of the sample studied.
A major part of the infrastructure contains various experimental techniques used to investigate mechanistic aspects of liquid and solid sorbents and membranes. All techniques offered are modern and the results obtained are expected to be of high scientific quality. The experiments can be conducted at relevant conditions and the equipment is run and monitored by skilled technicians/scientists. The choice of the right experiment/experimental conditions for a specific test should be established through discussion with our experts. The main aim of such studies is to examine why materials work as they do which again will form the basis for the development of improved materials for a certain application. Typical studies might include:
We offer the above-mentioned experiments to be carried out in one infrastructure. Skilled scientists and technicians are available to assist visiting partners. Also, a desk with internet access will be available during the stay. Beside the infrastructure itself are more standard laboratories where sample preparation can be performed are available.
SINTEF Industry has implemented and maintains a quality management system which fulfils the requirements of the standard NS-EN ISO 9001:2008 within research and development within materials technology, advanced materials and nanotechnology, applied chemistry and biotechnology, oil and gas, and green energy and process industry.
