Method 201A - PM10
Method 201A applies to the in-stack measurement of particulate
matter emissions equal to or less than an aerodynamic diameter
of nominally 10 microns, PM10, from stationary
sources. A gas sample is extracted at a constant flow rate through
Apex Instruments cyclone, which separates PM greater than PM10.
PM less than PM10 is collected on the in-line
filter. In order to maintain a cut size of 10 microns in the cyclone,
the flow rate must be maintained at a constant, discrete value
during the run. Our cyclone meets the design specifications of
Method 201A and allows use of the equations in Method 201A to
calculate the constant sample flow rate.
PM10 / Method 201A Cyclone and Accessories
The PM10 Cyclone is built to US EPA specifications
for Method 201A testing and is designed for in-stack measurement
of particulate matter equal to or less than 10 microns. The shank
has a 5/8 inch outer diameter for easy adaptation to Method 5
Probe Assemblies. The cyclone is enclosed in a sturdy plastic
case with eleven nozzles.

PM10/PM2.5
Method applies to the in-stack measurement of particulate
matter equal to or less than an aerodynamic diameter of
nominally 10 (PM10) and 2.5 (PM2.5
) microns from stationary sources. The sampling train and
operation is identical to Method 201A except that the PM2.5
cyclone is inserted between the PM cyclone and the filter.
The PM10 cyclone collects particulate
matter greater than PM10 while the
PM2.5 collects PM less than PM10
and greater than PM2.5. The in-line
filter collects PM less than PM2.5.

Cascade Impactor (CI-700) with Precollector Kit (PRA-K)
 |
Apex
Instruments’ CI-700 Cascade Impactor is an in-stack,
multi-stage cascade impactor which can attach to standard
EPA and ASME particulate sampling trains and specifically
used for measuring the particle size distribution in stationary
emissions. The Model-700 cascade impactor consists of seven
impactor stages that can separate particle from 0.2 to 17
micron diameter (aerodynamic), solid or liquid, into eight
size classifications which can be used later for weighing
or chemical analysis. Lightweight disposable collection plate
inserts of stainless steel foil allow improved weighing precision
and reduce the need for extra sets of collection plates. |
|
A Cyclone Precollector (PRA-K), used at the inlet
of the impactor not only reduces the particle bounce and
re-entrainment problems but also minimizes the chances of
particle overloading at the first impaction stage. The precollector
allows for right angle sampling and for the cascade impactor
to be inserted through a standard port. The precollector
kit includes 6 nozzles, from 1/8 inch to 1/2 inch diameter,
and the connecting tube. The precollector can attach to
most commercially available impactors. Sold separately.

Particle Sizing Data Reduction Software
|
This Windows-based Cascade Impactor
Data Reduction System (WINCIDRS)
calculates particle size distribution of stack particulate
matter (PM) taken with the Mark III Impactor as well as
particle-sizing cyclones. Developed by stack particle analysis
experts, this software reduces the time and chances of error
involved with reducing particle sizing data.
|
|
• Calculates each stages aerodynamic cut point, DP50,
needed to reduce particle size data
• Calculates and stores ancillary data such as dry
gas composition and moisture content
• Reduces velocity traverse data and aids in selection
of sample flow rates and ideal nozzle size
• Calculates flow rates and dwell times required for
PM10 and PM2.5
sampling traverses
• Calculates fractional efficiencies of control devices
from samples obtained at inlets and outlets
|
| The PM10/2.5
Software Program (PM-2.5-10C) is extracted from WinCIDRS
and simplified for use only with PM10
and PM2.5 cyclones. The calculations
are similar to the WinCIDRS just scaled-down specifically
for cyclone data reduction. Although the calculations for
the cyclones are not as involved as the cascade impactor,
the calculations are still intensive enough to demand computer
software. |
