Early in the history of OSM Desotech Inc., we realized, through customer feedback, that
liquid-borne particulate contamination is detrimental to many ultraviolet (UV) and electron
beam (EB) curable products. We became aware that contaminants, particulate and
otherwise, had to be carefully monitored if they were to be controlled. In terms of
particulate contaminants, raw materials, processing, packaging variables and in-house
environmental factors were all taken into consideration. The absence of effective and
accurate quantitative means for measuring liquid-borne particulate contaminants became
evident, It is at this point that we started focusing our efforts on the characterization of
particulate contamination. The measurement of particle size and determination of particle
size distribution cover multiple disciplines making it very difficult, if not impossible, to
professionally include the entire range of topics that must be considered. The scope of
this article will be limited to the counting and sizing of liquid-borne particles present as
contaminants in ultraviolet and electron beam cured materials covering the particle size
range from 2 to 100um.
