One Minute Read: Selectable Particle Size

While most existing cleanroom standards and guidelines spell out the particle size of interest very specifically, these practices provide the ease of data reference for compliance. In meeting compliance and monitoring requirements, having a fixed particle size is certainly very helpful.

However, achieving compliance is not the sole purpose of owning an aerosol particle counter, as there are times when cleanroom operators need to investigate specific particle size of interest to troubleshoot an abnormality or to comply with process requirement. Under these circumstances, a particle sizer or particle impactor is required so that discrete particle sizing can be performed to understand the particle size of interest.

In the past, this has become a reason for organizations to invest for an extra instrument such as a particle sizer. Today, this additional spending can be spared thanks to Particle Measuring Systems (PMS)’s Lasair® Pro! — With its superior laser optical bench, ultra-wide angle light scattering collection, advanced electronics, multiple stage of gain to effectively overcome non-linearity of monotonic light scattering curve, and the unique feature that allows a maximum of 8 channels with different particle sizes of interest, users can now measure particles with different sizes using just one particle counter!
