Calibration

This range of Estapor® Calibrated Standards Microspheres is used in scientific and industrial laboratories for the calibration and the standardization of particle measurement systems. They also can be used in quality control programs and development of new analytical methods in numerous fields.

Principle of measurement: First ECS sample and Standard Reference Material 1690 or 1691 (NNBS) are mixed together. Then, this preparation observed by Transmision Election Microscope (TEM) and photo are taken. These ECS Microspheres have been calibrated according to the recommendations of The National Institute of Standard and Technology (NIST). The average mean microsphere diameter was determined by using TEM (Transmission Electron Microscopy). Initially the size is optically determined via TEM microscopy and then, the real size is obtained by multiplying this value with the effective magnification rate of the microscope when taking the photo.

Our Calibration Standard Microspheres are supplied at 0.5% concentration in water (50mg/10ml).
