A syringe sampler represents the simplest delivery system for precisely delivering a sample to the particle counter. The precise motion of the syringe pump produces a steady flow of fluid that is free of pulsations…
ISO 21501-4 Calibration Overview
The introduction of ISO 21501-4, in 2007, requires the adoption of Pulse Height Analysis (PHA) particle sizing technology and particle standard spheres with international traceability and uncertainty equal to or less than ± 2.5%. The standard defines two main goals: improve the instrument-to-instrument data correlation and improve the particle count accuracy.
Should Anaerobic Cultures Be Part of GPT?
Anaerobic environmental monitoring is not a routine process, but is occasionally performed to detect potential anaerobic microbial contaminants, particularly those related to contamination by personnel.
Cleanroom Action and Alert limits
You’re going to have a high stream of data if you want a fast response to contamination events. Decide how long you want your samples to run to determine how fast. One minute samples are an immediate indicator that aren’t completely overwhelming…
5.0 μm 粒子采样推荐粒子计数器
As the aerosol particle counting experts, Particle Measuring Systems recommends against the use of 0.1 CFM particle counters to sample and monitor 5.0 μm particles. Instead, use a 1.0 CFM flowrate model like the Lasair® III particle counter to provide an adequate sample for the detection of 5.0 μm particles.
VHP Resistance and IsoAir® Pro Series Particle Counters
Vaporized Hydrogen Peroxide is a strong oxidizing agent and has been proven as a sterilizing agent in enclosed filling isolators for many years. As the increase of applications using isolators increases, so does the need for robust sensors capable of withstanding these environments. IsoAir® Pro Remote Particle Sensors contain an internal flow path that is designed to be resistant to the harmful effects of VHP.
Considerations and Steps for Building a Contamination Control Strategy – Series Part 4 of 4
Conventional approaches to contamination control are changing. They are being driven by the need to anticipate contamination events, rather than simply react to them, and new regulations are supporting this shift in thinking. Defining a Contamination Control Strategy (CCS) is unique for each process and requires an intimate understanding of both the process and how to implement an effective strategy. This blog series goes into depth on both topics.

How to Achieve Quality by Design (QbD) in a new Pharmaceutical Fill Line: Intro and Regulatory (Series Part 1 of 6)
In this blog series we will examine what a new fill line looks like with and without QbD implemented at the design phase. We will study each critical area of the fill line and the activities necessary to effectively bring the control features into effect. These examples come from real-world applications experienced by the Particle Measuring Systems’ Advisory Services Team. Our team has over 70 years of collective experience working in and advising cleanroom users around the world.
了解鉴定哪里是样本采集点
随着环境系统设计中，无论是在制药洁净室或清洁装置（RABS，隔离器等）进行，我们经常问应该在什么地方采样点粒子监控。
