Selecting an Airborne Particle Counter: Number of Monitoring Locations (Series Part 3 of 4)
After choosing the monitoring method, determine how many monitoring locations or particle counters you need. If the area of your cleanroom is 1,000 m2 or less, use Table A.1 provided in ISO 14644-1:2015. If your area is greater than 1,000 m2, first divide the cleanroom area (in m2) by 1,000. Then multiply this number by 27. Remember that this is the minimum number of locations. You can always ...

Planning for a Gas Monitoring System
Do you need a gas monitoring system? Then you already know which gases you want to monitor, you probably have an idea of measurement ranges and accuracy requirements, and perhaps you have a budget for the system. But which other aspects have to be considered, and how do you actually design the system? Whether it is about air quality monitoring, continuous emissions monitoring or process control, ...

How Does a Gas Analyser Work?
Whatever you want to detect, you need to identify a property of the object that is easy-enough to measure. When it comes to monitoring and analysis of gaseous species (atoms or more commonly molecules), it turns out that it often is possible to utilize the optical properties of the gas. You need a light source, a light detector, and a characteristic behaviour of the gaseous species in question ...
