Particle Contamination in High-Purity Process Chemicals

Vaporized Hydrogen Peroxide (VHP) Resistance Testing for MiniCapt Pro Microbial Sampler

Vaporized Hydrogen Peroxide (VHP) serves as a potent oxidizer and has long been acknowledged for its effectiveness in sterilization within enclosed filling isolators. With the rising prevalence of isolator applications, there’s an increasing demand for robust samplers capable of enduring such environments. The MiniCapt® Pro Remote Microbial Sampler features an internal flow path designed to resist the corrosive impacts of VHP.

Particle Counter Counting Efficiency

Understanding particle counter counting efficiency helps you to identify the best solution for your application and understand the data from the particle counter.

All non-volumetric particle counters have sample volume growth to some degree, which results in a lower particle counting efficiency at the lower limit of detection and variable particle counting efficiency across the lower channel sizes. This increase in particle counting efficiency with particle size means the counting efficiency measured at a single particle size in this channel cannot be applied to the entire channel. Use of the particle counting efficiency as a correction factor does not result in “true” particle counts.
