Applications

Instrument Calibration

Particle Size Standards provide third party traceability to national and international standards. Traceability is documented through an

unbroken chain of measurements (with specified uncertainties) that are tied back to the standards. Our products can also help in the

development and testing of new analytical instruments and particle size analyzers.

Routine Checks

By performing routine checks, the user will be alerted to any shift in laser function or calibration curve shape. These checks will alert the

user to instrument problems thus avoiding misleading or inconsistent data.

Spacers

Spacer particles establish the correct cell gap during the assembly of liquid crystal displays and other precision microelectronics. Glass

particles have sufficient thermal stability to withstand heating and also good compression strength so as to not break or fracture under

pressure.
