Analysis of microplastics

Study of microplastics in drinking water, ecosystems and food

  • Application description
  • Raman spectroscopy
  • FT-IR spectroscopy

Microplastics are small particles or fibers of polymeric materials (polystyrene, polypropylene, polyamides, phthalates etc.) and often inorganic compounds, smaller than 5 mm. We can encounter either primary microplastics, which have already been produced in this form, or secondary microplastics, which are the product of decomposition. Virtually all plastics exposed to abrasive or UV radiation are subject to this process. Then, they uncontrollably enter ecosystems and become part of the food chain. Due to the extensive use of plastics, the pollution of water, soil, and even the air and animal bodies by microscopic particles has recently become an increasingly serious and mediated problem. In addition to the proven harmful effects on ecosystems and human health, the presence of microplastics in bottled water and other beverages can also have a negative impact on the food industry, damaging otherwise reliable producers. Combating this relatively new type of pollution requires a thorough understanding of the issue.

The first thing is to discover the origin of microplastics and map their path in different ecosystems. However, this adventure begins with the detection and most accurate identification of these substances in various types of samples: drinking water, service water, food industry products and also in the air.

The combination of FT-IR microscope Nicolet iN10 MX, Raman microskope Nicolet DXR3xi and spectroscopic programs OMNIC and OMNIC Picta including spectral libraries of polymers is the complete solution of the microplastics analysis in a large range of their sizes (0.5 - 5000 μm) in various types of samples. It allows both the identification of these particles (and thus begins the detective work to determine their origin) and their quantification in samples. If you are interested in identifying particles below 0.5 micrometer, we offer a solution in the form of (FT)-IR SNOM technology Neaspec.

The Nicolet DXR3 Dispersi Raman Microscope is an instrument designed for applications requiring high spatial resolution, ease of sample preparation, and the use of the strongpoints of Raman microscopy.
The user-proven DXR Raman microscope is now available in the new version of the DXR3xi with a high-performance EMCCD detector and a microscopic table with the possibility of nanoslift for super fast Chemical Imaging of your samples.
Thanks to the integrated touch screen, the i-Raman Pro can also be used without an external PC or laptop.
The Nicolet iN10 is a revolutionary Fourier transform infrared microscope that offers the simplicity of an FT-IR spectrometer along with the ability to measure samples down to several micrometers in size. It has been developed specifically for analysts, technicians and scientists who know exactly what information they want but do not have time to become a microscopy specialist, and for experts looking for better answers in a faster way.
The Nicolet iS50is the first scientific one-touch FT-IR spectrometer. Based on extensive experience with previous successful Magna, Nexus and Nicolet X700 scientific systems, a new FT-IR spectrometer has been developed which, thanks to a wide range of measuring accessories and interconnected analytical software, delivers a universal material analysis system with unrivaled ease of use.
The Nicolet iN10 MX infrared microscope brings all the advantages of the Nicolet iN10. Up to three integrated detectors are a new option, including the patented MCT-A imaging detector. Infrared imaging brings revolutionary spectra and map measurements.
SNOM (near field scanning optical microscopy or NSOM) is a microscopic technique that exceeds the resolution limit due to the properties of attenuated waves. The distance between the detector and the sample is less than the wavelength of light when measured, and this is used in optical microscopy, among other things, for its ability to increase the contrast of nanoparticles.
