Our expertise



Over the past decades, it has been common practice to validate and calibrate particle sizing and particle counting instruments with a standard that is traceable to standard reference materials from the National Institute of Standards and Technology (NIST) of the USA. With the ever increasing demand for instrument calibration and validation according to more internationally standardised procedures (ISO), Applied Microspheres has developed particle size standards and count controls that are not only NIST traceable, but also traceable to reference materials certified by an ISO 17025 accredited laboratory. Applied Microspheres’ particle size standards and count control product lines therefore meet the highest international metrological standard available.

The basis for the development of such standards is Applied Microspheres’ ability to produce large batches of (polymer) nano- and microspheres with very narrow size distributions. This expertise is also fundamental for the development of other products, such as zeta potential standards, multi-modal size standards, flow cytometry instrument controls and custom made instrument controls on OEM basis. Applied microspheres also offers a variety of (fluorescent) dyes that can be incorporated in the polymer matrix of their particles.
