Monitoring particle levels is crucial to maintaining cleanroom integrity and ensuring product quality across many industries. Among the tools used, handheld particle counters stand out for their versatility, ease of use, and practicality. Here’s a straightforward look at understanding handheld particle counting - what it is, why it matters, and when it’s the right choice. ...
In this application, total suspended particulate (TSP) samples were collected using a medium-flow air sampler with imported 0.8Dum glass fiber microfiltration membranes. After sampling, the filters were stored in a desiccator. Microwave digestion was employed as the pretreatment method, offering rapid sample ...
Airborne Particle Counters (APCs) play a critical role in monitoring and maintaining the cleanliness of environments where air purity is essential, such as cleanrooms. There are two fundamental types of APCs: portable and fixed-point remote. Each type has unique features and applications, making them suitable for various scenarios in contamination control. Portable APCs are self-contained units ...

The SAS II delivers particle size measurements in the range 0.2 to 75µm, a range that tends to be too fine for economic and/or accurate sizing by sieve analysis. It utilizes the non-destructive air permeability technique which was commercialized many decades ago specifically to meet the requirement to size finer powders. ...
There has been considerable interest recently generated regarding emergency air sampling protocols as a result of the Fukushima accident in Japan. A major concern involving air sampling requirements is the accurate determination of gaseous-radioactive iodine species emitted from the NPP to the environment as a result of an ...
INTRODUCTION The calibration of an air sampling instrument using a reference air flow calibrator requires attention to scientific detail in order to establish that the instrument’s reported values are correctly stated and valid under the actual operating conditions of the air sampling ...
According to NIOSH, both nickel and chromium may cause cancer. Sampling Methods There are many ways in order to detect and monitor welding fumes but the most reliable and accurate way is to use an air sampling pump such as the new GilAir Plus by Gilian. There are many sampling heads that can be used for a variety of ...
Figure 3 shows the complete setup of the StackGuard including the loop line for sample preparation. The sampling line (c) takes the sample from the stack (d) at a flow rate of 60 m3/h using a blower (e). ...
Often air sampling systems have used passive flow methods based on orifices, needle valves, venturi meters, or rotameters to monitor the sampling rate. ...
