Introduction to Source Sampling
Apex Instruments, Inc. offers an extensive line of equipment
and supplies for sampling stationary source emissions for pollutants
in accordance with US EPA Reference Methods. The majority of the
methods are generally classified as either Isokinetic or Gaseous
Sampling Methods. During Isokinetic Sampling the sample rate is
adjusted proportional to the source flow rate, while with Gaseous
methods the sample is normally pulled at a constant lower rate.
Many of the gaseous methods can be conducted using the Isokinetic
equipment with the proper accessories. A partial list of some
of the methods is included below.
Applicable Methods:
The Apex Isokinetic Source Sampler System allows the operator to monitor gas velocities, temperatures, pressures and sample flow rates for maintaining isokinetic sampling conditions. During an isokinetic test, parameters, including gas velocity and temperatures, are periodically monitored and the sampling rate adjusted so the velocity in the nozzle opening equals the velocity of the approaching stack gas to obtain an unbiased particulate sample.
Isokinetic testing requires a thorough understanding of the first
five test methods presented in the CFR 40 Part 60 Appendix A.
While US EPA Method 5 provides the general protocol for operating
the sampling train to collect a representative sample, US EPA
Methods 1 through 4 prescribe techniques underpinning the sampling
activities associated with Method 5. Together, these methods outline
the basic protocols for determining particulate concentrations
(grains per dry standard cubic foot or milligrams per cubic meter),
as well as emission rates (lbs/hour or kg/hour).
| The basic Method 5 sampling train is easily adapted to test for many other gaseous and particulate parameters of interest from stationary sources. Parameters of interest may include metals, polychlorinated biphenyls (PCBs), dioxins/furans, polycyclic aromatic hydrocarbons (PAHs), particle size distributions and an ever increasing group of pollutants tested for with adaptations of this basic test method. While the different methods are designated by other US EPA or agency method numbers, they are variations of Method 5 procedures such as: different impinger solutions, the use of organic resin traps, different filter media, temperatures or a range of alternative procedures. |

The Apex Isokinetic Convertible Method 5 Intermediate Sampler
System provides a reliable and versatile foundation for performing
most isokinetic testing methods. The Convertible Intermediate
Sampling System is designed for the professional who must perform
test after test at various locations in an efficient manner. The
system can be used in the standard rigid or flexible arrangement.
The Convertible Intermediate System is designed to provide maximum
efficiency and the best value for your money. The Deluxe Glassware
Set allows for speedy changes between runs.
