The XD-502 Source Sampler from Apex Instruments is designed for manual, isokinetic sampling of
gaseous pollutants from stationary sources, e.g. stacks, flues, vents or pipes. The console is most
commonly used for EPA Methods 5, 17 and 23.
The Source Sampler is easily adapted to test for a wide range of pollutants from stationary sources,
such as particulate matter including PM 2.5 and PM10 fractions, metals, polychlorinated biphenyls
(PCBs), dioxins/furans, polycyclic aromatic hydrocarbons (PAHs) and many more pollutants with
adaptations of the basic isokinetic test method.
The purpose of this manual is to provide a basic understanding of the Apex Instruments XD-502
source sampling console. The XD-502 is applicable for use with a variety of US EPA sampling
methods and other isokinetic sampling procedures.
Additionally, this manual provides the users with a reasonable amount of reference information on
system configuration, calibration procedures, maintenance and troubleshooting as it applies to the
specific product and the US EPA Regulations.
Method 5 - Determination of Particulate Matter Emissions From Stationary Sources
Method 17 - Determination of Particulate Matter Emissions From Stationary Sources
