In highly regulated industries such as pharmaceuticals, biotechnology, and advanced manufacturing, contamination control is non-negotiable. Airborne particle monitoring plays a central role in ensuring cleanroom environments meet strict regulatory requirements like EU GMP Annex 1: 2022 and ISO 14644. One of the most effective tools for achieving continuous, reliable oversight is remote ...
Introduction To maintain compliance with regulations and produce products with limited risk, pharmaceutical companies manufacture products in controlled environments such as cleanrooms. Cleanrooms reduce the risk of variability and particle contamination and are defined as rooms in which air filtration, air distribution, utilities, materials of construction, and equipment are maintained in a ...
In the pharmaceutical manufacturing industry, ensuring sterility and minimizing microbial contamination are critical for maintaining product quality and safety. Microbial sampling is a key component of environmental monitoring, and understanding the optimal criteria for sampling can significantly impact the effectiveness of sterility assurance ...
Gas Sampling in Cleanrooms In cleanrooms, especially those classified ISO 5 or cleaner, maintaining contamination control is paramount. ...
Customer: WWTP in Tokyo, Japan Material: Sludge flue gas dust Installation point: After dust collector Function: dust monitoring ...

What then remains is long-term sampling, with equally long intervals between the sample analyses. Special attention must then be paid to the sampling rate, where the sampling speed at the nozzle should be the same as the speed of the surrounding flue gas. This is called isokinetic sampling. ...

As the aerosol particle counting experts, Particle Measuring Systems (PMS) recommends against the use of 0.1 CFM particle counters to sample and monitor 5.0 μm particles. Instead, the best particle counter has a 1.0 CFM flowrate model such as the Lasair Pro Particle counter to provide an adequate sample for the detection of 5.0 μm particles. ...
In our previous blog, we learned about ways to mitigate particle losses in transport tubing from the sampling inlet near a critical point in a process, to the particle counter. Here we’ll learn about the ways in which some losses are there to stay. ...
In our previous blog in this series, we learned about the many forces that can act on a particle when it travels through tubing. Now, let’s take a look at how we can mitigate these forces on our particle data. ...
The Conditions for Data Comparison When looking at data from two different particle counters, you’ll need to know if your sampling was performed with isoaxial and isokinetic airflow. But what do these terms mean? ...
An isokinetic sample is taken from the duct and dioxin is trapped in an absorbing material. ...

In this article we introduce you to the world of continuous dioxin monitoring and the Gasmet GT90 Dioxin+, which is an exceptionally robust dioxin sampling system. Did you know that it was designed to sample even the lowest dioxin and dioxin-like compound concentrations in harsh industrial environments, even in subfreezing conditions? In addition to dioxins, the system is capable of measuring ...

Once the most suitable method for the continuous emission monitoring has been decided, the measurer can use the following procedure, recommended by the Technical Research Centre of Finland https://www.vttresearch.com/: Choosing the measuring platform Choosing the flange mounting locations Analyzer installation and possible calibration Choosing number of measuring points and locations in ...
These substances are considered by many institutions as key pollutants, but their low concentration (ng/m3 in emissions), the difference of toxicity between the different congeners, their presence in all phases (dust, droplets and gases), lead to sampling diffi culties (long time sampling, reliability of instrumentation, experienced technicians...) and complex ...
The following describes particle behavior mechanisms and will assist in the understanding of sampling difficulties and how to improve the efficiency of sampling using a particle counter. ...
Does it need a minimum flow speed in order to sample? What is that? Absolutely! The internal pump in the SL will adjust the intake velocity to match the ambient flow speed in order to make the sample intake isokinetic. ...
To design the most efficient system, an isokinetic dust sample was collected at the stack and measured by ACS in a laser sizer to obtain the Particle Size Distribution (PSD). ...
