Technology behind the Data – PM2.5 Particulate

By Jim Shorey PM2.5 is Particulate Matter smaller than 2.5 microns in size. Particulate Matter such as wood smoke is often measured using the principle of Beta Radiation Attenuation and Nephelometer Light Scattering Detection. Looking at the flow diagram below, particulate is drawn into the Inlet via a vacuum pump.  The Inlet has a PM10… Show more

Technology Behind the Data – Ozone

Ozone Jim Shorey Ozone gas is commonly measured by instruments with UV Photometric Technology Looking at the Flow Schematic shown below in Figure 1-2, we see the layout of an Ozone Analyzer. This unit includes an internal Air Sample Pump, which draws Ambient Air into the port labeled SAMPLE. Once the sample enters the sample… Show more
