Aerospace and Defense Particle Counting

Typical ISO class cleanrooms in industries such as Pharmaceuticals or Semiconductors necessitate a standard set of demands for particle counting instrumentation and accessories to help customers achieve the required specifications outlined by regulatory committees. The Aerospace and Defense industries need to meet their own unique set of requirements that are often more variable and customer-specific than in other markets; this is something Particle Measuring Systems instrumentation and expertise can support.

Ultrapure Water and the Application of Particle Counters in the Smelting and Refining Industry

This paper explores the application of a high-sensitivity liquid particle counter (Ultra DI® 20 Plus) to optimize ultrapure water (UPW) filtration performance in copper smelting and refining operations, and it demonstrates how sulfuric acid, a by-product of the process, can be refined to meet the high purity standards required by the semiconductor industry.

Compressed Gas Risk Assessment-
A Significant Piece of a CCS

Compressed gas systems play a critical role in pharmaceutical manufacturing and must be included in your Contamination Control Strategy (CCS). Annex 1 requires these systems to be properly designed, qualified, and monitored to prevent contamination.

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.

Microbial air sampler environmental monitoring biocapt single use sterility assurance

Key Factors for Optimizing Microbial Air Sampling

Microbial air sampling in pharmaceutical manufacturing relies on surface, passive, and active methods—each using media like agar to capture microbial growth. While techniques vary, accurate results depend on collection efficiency. This paper focuses on active air sampling and how to optimize performance across all methods.

Nanoparticle Counter NanoAir 10 for semiconductor tool contamination monitoring

Airborne Nanoparticle Counter to Detect Contamination in Semiconductor Tools

The increasing attention on driving better product yield performance with advanced technology nodes has drawn reasonable discussion for in-tool monitoring to reduce nanoparticles that can have an impact on yield. With that in mind, Particle Measuring Systems (PMS) launched the new NanoAir™ 10 Condensation Particle Counter that measures particles down to 10 nm and the ParticleSeeker™ Smart Manifold system which is the first-ever manifold designed to handle nanoparticle transport. This product will unlock a new world of monitoring possibilities, providing a look into a current blind spot of the requirements and needs in the industry.

isokinetic probe particle counter for unidirectional air.

Isokinetic Probe Particle Counter Air Flow Rate Requirements

There is an optimum air flow rate within unidirectional environments which is required for Isokinetic particle sampling to act as a sheathing air that washes particles from a potential contamination source away from the process risk before being exhausted from the process area. This ensures that this potential contamination does not extend beyond a field of control. This flowrate was historically defined as 90 feet per minute, which roughly converts to 0.45 m/s. Current requirements suggest…
