Suzhou Nanoparticletech Co., Ltd. develops and manufactures polystyrene standard particles with a Coefficient of Variation (C.V.) value of less than 1%. The products are measured using precision instruments such as Dynamic Light Scattering, TEM, SEM, and Optical Microscopes, and are calibrated with standard particles traceable to NIST.
The precision of standard PS (polystyrene) particles in size measurement is not only reflected in their highly accurate measurement results but also in the entire measurement process that strictly adheres to the measurement methods provided by the National Institute of Standards and Technology (NIST) in the United States. Through this method, the size measurement results of each batch of particles can be directly traced back to the NIST standard scale, ensuring the authority and credibility of the data. The particle size of these standard microsphere products is determined using a series of internationally recognized advanced equipment and techniques, including but not limited to light scattering instruments, Scanning Electron Microscopes (SEM), Transmission Electron Microscopes (TEM), Dynamic Light Scattering instruments, and high-magnification optical microscopes. The comprehensive application of these technologies ensures high consistency and repeatability in particle size measurement, with a Coefficient of Variation (C.V.) value of less than 1%, demonstrating the excellent performance of these standard microspheres in terms of precision and stability.
Moreover, the production and inspection processes of standard PS particles are based on a strict quality control system. From the selection of raw materials to the final product's packaging, storage, and transportation, every step is carefully designed and rigorously managed to ensure that each batch of microsphere products meets the high standards of scientific research and industrial application. This relentless pursuit of quality, combined with the application of advanced measurement technologies and methods, has made standard PS particles an important tool for precise measurement and experimental analysis in fields such as scientific research, medicine, and chemical engineering. They provide users with highly reliable and consistent experimental results, thereby advancing technological progress and development in related fields.
