Whitehouse Scientific has produced a 500kg batch of silver-coated glass microspheres of 15 to 150 microns to initiate external testing of a new particle-size standard.
This opaque standard is expected to have universal application and be compliant to the latest ISO and USP standards.
LGC Standards will carry out the statistical analysis of test results.
Subdivided into single-shot bottles from 2.5g down to 100mg, the opaque standard is suitable for all particle sizing methods, from laser diffraction and image analysis to optical-zone sensing devices and for wet or dry analyses.
