Compared to the human eye, a spectrometer can be certainly regarded as a scientific instrument. Production and marketing of scientific equipment have now become a profitable industry.

Some 100 to 150 years ago, chemists performed most solution analyses observationally. The colour of the solution and its intensity indicated the proportion of the substance in the solution. It took another 20 years to invent the first optical spectrometer. The chromatograph/mass spectrometer is a recent invention. Production and marketing of scientific equipment has now become a profitable industry.

Today - Simpler - Spectrometer - Laboratory - Measurements

Today, a simpler spectrometer used only for laboratory measurements costs 10,000 to 15,000 euros, and it is updated almost every year. Equipment manufacturers entice researchers with new and more attractive models. But are constant upgrades justified? After all, the technology used for standard chemical measurements has often remained unchanged for decades, and the emergence of new instruments on the market does not necessarily mean a significant quality leap in measurement.

Researcher Mihkel Koel of the School of Science, Department of Chemistry and Biotechnology says, "Being green chemists, we are battling to reduce the ecological footprint of chemical measurements. Measurement results of the same quality can often be obtained faster by e.g. a 500 euro cell phone. In the outdoor environment and in the circumstances requiring a rapid result, we can obtain a completely reliable result by using a free mobile application rather than expensive instruments."

Principle - Chemistry - Results - Methods - Professor

It is the fundamental principle of green chemistry to obtain measurement results quickly and as easily as possible by practising green and sustainable methods. Professor Emeritus of the School...
