STEMart now offers Particulate Matter Testing Services with a range of particulate matter testing from <0.001 μm to >3,000 μm. The team of experts can provide accurate analysis and material ...

A nominal efficiency rating is often understood to be the particle size above which the filter stops 75%, but there is no standard definition. Absolute is assumed to be the largest single particle ...

As semiconductor devices become more complex and the critical particle size for today’s cutting-edge technology nodes falls into the sub-10 nm size range, controlling and mitigating potentially ...

For the past 10 years, monitoring ultrapure water (UPW) systems with a legacy standard of 50 nm sensitivity has been successful and efficient. Particle counts at 50 nm are widely used to evaluate UPW ...

The general procedure for Microscopic Particle Count test is to wet the inside of a filter holder containing a membrane filter with a few milliliters of particle-free water, transfer the total volume ...
