The research project titled "Development of Polystyrene Particles as Thailand Reference Materials (TRMs)" aims to produce polystyrene particles which will be certified by National Institute of Metrology Thailand (NIMT) as Thailand reference material (TRM). Polystyrene latex have been used to calibrate instruments such as scanning electron microscope (SEM) and dynamic light-scattering technique (DLS) to ensure their measuring accuracy. Currently, the country relies heavily on imported certified reference materials (CRMs), which are often costly. This project seeks to develop polystyrene particles with uniform size distribution, high stability, and well-characterized properties in accordance with international standards. The initiative is expected to enhance Thailand's metrological capabilities, strengthen scientific infrastructure, and reduce dependency on foreign materials. Moreover, the resulting TRMs will support quality control efforts in both industrial applications and environmental research.
