Microplastics - IR Microscopy Helps Exploring a Global Problem

What are microplastics? How do you recognize microplastic particles and where do they come from? Every year, megatons of microplastic particles are introduced to our oceans. The analysis of the origin and consequences of this pollution is more important and urgent than ever.

Our oceans, rivers and lakes, its inhabitants and therefore we are facing a serious problem. The increasing pollution by microscopic plastic particles that find their way into our food chain through marine animals and plants or drinking water.

These contaminations are of different origin. On the one hand, they come from the enormous amount of plastic waste that floats in our seas and constantly loses its mass due to weather and abrasion. On the other hand, there are ingredients of cosmetic products that accumulate in our waters through wastewaters.

Almost daily, the list of places where microplastics are found in high concentrations is extended. Riverbeds, natural fertilizers, soils and even drinking water also show noticeable amounts of contamination.

To investigate the origin, causes and consequences for humans and nature, FTIR microscopy has become an established standard method for the analysis of microplastic particles. It ensures a safe and easy identification of all polymer types and offers high potential for automation. Mapping and chemical imaging make it possible to determine thousands of plastic particles separated on filters within the shortest possible time and fully automatically.

Bruker's FT-IR microscopes HYPERION and LUMOS are already being used in research institutes around the world to detect and analyze microplastics.

Let us face this global threat. Together.
