CEMIS in brief
CEMIS is a contract based joint
centre of University of Oulu,
University of Jyväskylä,
Technology Research Centre VTT,
Centre for Metrology and
Accreditation MIKES and Kajaani
University of Applied Sciences.
CEMIS is founded Kajaani in 2010
and employs around 110
professionals. CEMIS specialises in
research and higher education in the
field of measurement and
information systems.
CEMIS´s mission is to provide
superior expertise, top-level
research services, and innovative
solutions for companies and
research organizations developing
and applying measurement and
information systems. For students
CEMIS offers an enthuastic,
innovative and international
atmosphere to educate oneself
toward future professions.
CEMIS focus areas
Optical spectroscopy Biosensors Imaging Measurements On-line solutions for analytics of water, other liquids, and
solids-liquids mixtures
Measurement and Information Systems for
Vehicles and Moving Machines
Wireless and self-powered solutions for
sensing, data transfer and position
Measurements for Well-being and Sport Computer Games and Simulators
Measurements for Process Industry and
Environmental Monitoring
Motivation
Share of bioeconomy in Finland in 2011: around 15 % of GDP (51 billion euros)
By 2050
Use of biomass will be doubled
Added value of biomass –based products will be doubled
Share of bioeconomy will reach 50 % of GDP
Need for new biomass –based products
Need for new production technologies
Need for new measurements
Business for research insitutes and companies like CEMIS, VTT, universities, Metso, Senfit, Outotec etc
Use of bioenergy will triple
in Europe and double in the
world by 2035

Polarisation spectroscopy
• ORD – photometry*
• Applicable for rather simple and transparent samples
Optical multi measurement
• Utilizing spectral complex refraction index and
transmission spectroscopy
• Applicable even chemically and physically complex
samples
Biosensor
• Based Ni/Co -oxide - MWNT (multi walled carbon
nanotubes) – electrode
• Applicable to chosen sugar compounds Arvinte A, Sesay A, Virtanen V, Carbohydrates electrocatalytic
oxidation using CNT-NiCo-oxide modified electrodes, Talanta,
2011, 180-186. * ORD = optical rotatory dispersion. Rotation of
polarization a as a function of wavelength of ligth

Example 2: Solids content of oil samples
using holographic imaging
• Particles are undesired • negative effect on particulate
emissions in motors • modern high precision motors are
prone to wear by particles • fuel filter and nozzle clogging in
motors • maximum allowed particle size
typically between 15 to 25 microns
• Digital holographic technology is used to realize four dimension information
• Sample cell was filled with a layer of oil and a holographic image was taken
• Stack of cross-sectional images were calculated from the hologram
• Cross-sectional images were compiled into a video for 4D information
Example 3: flow cytometry
• Flow cytometry is a measurement technology used for detection of microscopic particles, counting particles and determining particle size distribution as well as determining their physical and chemical properties
Example 4:
On-line sensors for trace elements
On-line sensors and analyzers based on optical spectroscopy, electro chemical sensors and biosensors
for detection of trace amounts of detrimental substances like toxic metals, alkali metals, sulphur
compounds, pathogens, lime-forming substances and bacteria.
