OUR ANALITYCAL METHODS |
▲ Back to What we offer ▲ |
Our FTIR microscopes, also referred to as µFTIR systems are infrared spectroscopy imaging systems used at our laboratory in Budapest. These instruments makes it possible to count the microplastic particles in the samples, identify their material types, shapes and measure their sizes, down to a size of 10 μm. The imaging system enables to cover a large area during analysis. Our FTIR-ATR devices are suitable for examining larger pieces of waste, packaging materials and even surface contaminants. FTIR techniques are non-destructive, so the samples can be further investigated with other methods, e.g., PYR-GCMS.
Our PYR-GC-MS device, a pyrolysis–gas chromatography–mass spectrometry instrument enables us to identify the various polymer types and their total masses in the samples. One advantage of this method is that it operates without a lower limit regarding particle size so we can use it for the analysis of particles smaller than 10 μm as well. Although it does not enable us to obtain a particle count, but it provides exact information on the total mass of the particles. It also tackles those dark, black particles, that are not possible to be analysed by FTIR, e.g. tire and road wear particles (TRWP).
R&D |
▲ Back to What we offer ▲ |
As a result, on one hand our experts have released significant publications in high-impact journals and became a well-respected part of the scientific scene. On the other hand, these developments help us to provide adequate services to our customers: the development is continuous, further to R&D activities our experts are involved in the work of standardisation committees on this field to improve the framework of microplastics sampling and analysis generally.

DEFINITION, SOURCES, RISKS |
▲ Back to About microplastics ▲ |
Microplastics - plastic particles with a size range of 1 μm to 5 mm - are nowadays commonly found in various environmental elements. Microplastics can be classified as primary or secondary microplastics. This is based on whether the microscopic particles are manufactured (primary) or whether they are the result of environmentally occurring fragmentation processes (secondary).
Microplastics, generated from different artificial polymers are poorly biodegradable in the environment, however through mechanical, chemical or UV-induced fragmentation they can enter several environmental compartments such as surface waters and soils. These persistent particles pose significant ecological and health concerns: can be ingested and accumulated by different organisms, possibly affecting human health and constituting an almost unimaginable risk to our future. Further to their physical occurrence their capability to accumulate and transport toxic chemicals and pathogens is considerable.
There are numerous sources of microplastics because plastics are widely used in our everyday life and in different industries, so microplastic testing are relevant for a wide range of stakeholders, not only actors in the water and environmental industry, but the chemical-, food- and light industry as well.

REGULATION, STANDARDISATION |
▲ Back to About microplastics ▲ |
The aim of this Directive is to prevent and reduce the impact of certain plastic products on the environment. Specifically, it means a ban on certain single-use products, that are wholly or partly made of plastic like ear buds and ballon sticks, cutlery, plates, straws, stirrers and food or liquid containers made of expanded polystyrene.
The Regulation prohibits the placing on the market of synthetic polymer microparticles (SMP) when placed on the market on their own or in mixtures if they are present in a concentration of at least 0.01% by weight in the mixture (product).
Synthetic Polymer Microparticles (SMP):
The regulation applies to:
The recast Drinking Water Directive (DWD) is tackling pollutants of concern, such microplastics. Microplastics should be monitored on a watch list between 2024-2029 to carry out a risk assessment.
Harmonised microplastic sampling & analysis under (EU) 2024/1441
The directive aims that Member States should take preventive measures to limit the risk that intentionally and unintentionally released microplastics reach urban wastewater and sludge.
Current and future standards for MP analysis Different standardisation bodies, such as ISO, CEN and ASTM are releasing standards defining not only principles and guidance, but microplastics sampling and analysis from different matrices in details. Among available standards, multiple documents are under development to cover this broad topic. |
