The presence of microplastics in water resources represents a major issue for human health, biodiversity and regulatory compliance. Standard XP T90 968-1 provides a methodological framework for identifying and quantifying these particles, guaranteeing accurate and reproducible analyses. ### What standard XP T90 968-1 says Published in December 2023, standard XP T90 968-1 specifies a method for the qualitative and quantitative analysis of microplastics in water intended for human consumption and groundwater. It is based on the use of microscopy coupled with vibrational spectroscopy, such as : - Fourier transform infrared spectroscopy ([FTIR](https://filab.fr/en/our-technical-resources/laboratory-analysis-ftir-microscopy.md)) - [Raman spectroscopy](https://filab.fr/en/our-technical-resources/laboratory-analysis-raman-spectroscopy.md) - [Pyrolysis GC-MS](https://filab.fr/en/our-technical-resources/py-gc-ms-pyrolysis-gc-ms.md) In particular, it makes it possible to : **Determine the size of microplastics** in the range 1 to 5,000 micrometres, count them and classify them by size range. **Identify the chemical composition of microplastics**, targeting polymers such as [polyethylene](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polyethylene-pe-materials-analysis-laboratory.md) (PE), [polypropylene](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/polypropylene-pp-materials-analysis-laboratory.md) (PP), [PET](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/laboratory-analysis-pet.md) and many others. ### Scope of standard XP T90 968-1 The standard applies to water with a low organic and suspended matter content, such as : - Ultrapure water complying with standard NF EN ISO 3696. - Water intended for human consumption. - Raw groundwater. However, it does not cover the characterisation of substances intentionally added to or adsorbed on the surface of microplastics or the determination of their geometric shape.
