Selecting an Airborne Particle Counter: Particles in Process Gases (Series Part 4 of 4)

This blog is about choosing a particle counter for gas applications. First, determine whether your process gas is reactive or non-reactive. Then decide its pressure range. Reactive Gases Examples of reactive gases include hydrogen and oxygen. These gases require a special particle counter stored inside a containment vessel. In addition, they require careful evaluation that the wetted materials ...

Particle Monitoring in Sterilizing Tunnels

Portable aerosol particle counters are designed to sample ambient air at 1 cubic foot per minute (1 cfm) and no greater than 35 oC. There are however applications which are based on ambient ...

ASTM D7758 - 11 Standard Practice for Passive Soil Gas Sampling in the Vadose Zone for Source Identification, Spatial Variability Assessment, Monitoring, and Vapor Intrusion Evaluations

Passive soil gas samplers are a minimally invasive, easy-to-use technique in the field for identifying VOCs and SVOCs in the vadose zone. Similar to active soil gas and other field screening techniques, the simplicity and low cost of ...
