Tetra-Cal ™ Development

Funded by the National Institute of Standards and Technology (NIST), Tetramer developed a commercial scale emulsion polymerization process to produce 100 nm and sub-100 nm diameter latex polystyrene particles, with a total population size variation of less than 2 nm.  NIST’s Engineering Physics Division of the Physical Measurement Laboratory is interested in using these latexes as sizing standards to provide traceability for critical measurement instrumentation, enabling new manufacturing technologies. In particular, the standards will be helpful to calibrate microscopy equipment, enabling previously unknown reliability across a variety of instruments. Dynamic light scattering particle size analysis and electron microscopy are used to validate the size and monodispersity of nanoparticles.
