2004 gets underway, we are pleased with how
the first quarter is progressing. This newsletter
will let you know of a few new and exciting
projects that are happening at Applied Porous.
we are excited to be opening a sales office
in Europe that will better allow us to
service both our European and Asian customers.
Please see the story at right.
we are pleased to add laser and electron beam drilled
porous metal filters to our product line. A new
partnership allows us to offer filters that, unlike
Sintered Porous Media, are not limited in the material
of which they can be constructed. Additionally,
the drilled media pore sizes begin at 50 microns
and there is almost no limit to the maximum hole
for the remainder of 2004, we are pleased to be
involved in trade shows that allow us to showcase
our products and services. Our first stop in 2004
will be at the Pittcon show in Chicago, March 7-12.
We will be at booth 4307 – stop by, say "hello" and
take a look at some of our new products. Please
visit our Web site for future trade show and new
an effort to better serve both European and Asian customers,
APT has established a sales office in Europe. Applied
Porous Technologies, Europe/Asia (APT-EA), will be based
in Sweden and managed by Dr. Christian Wegner. Christian
has over 20 years' experience working with chromatography
applications – most recently as the Vice Managing
Director for VICI Jour Research.
this office, we will provide our European and Asian customers
with a more convenient option to deal directly with the
manufacturer. As this will be a stocking sales office,
product will be available for shipment directly to the
European Community without the need to handle cumbersome
paperwork. For more information on the new office, please
visit our Web site, or contact our European office directly.
The contact information for the European office is:

in combination with the Air Force Research Lab Munitions Directorate,
has manufactured a Low Cost Autonomous Attack System, better
known as LOCAAS. This powered vehicle is designed to be launched
from a high-altitude flight and then find its intended target.
is powered by a 30 lb. thrust class turbojet engine manufactured
by Technical Directions Inc. (TDI), Ortonville, MI.
Applied Porous was contacted by TDI to manufacture a specialty
filter for this engine that would keep foreign material from entering
the bearings and affecting the performance of the engine. Vern
Brooks, TDI President, had detailed plans for the engine and the
chose Applied Porous after searching the Internet. Once
blueprints were provided, Applied Porous fabricated the
filter and it worked like a charm. "The Applied Porous
filter was made exactly to spec., and its quality is evident
in the LOCAAS's performance," Brooks said.
the LOCAAS has recently gone from the laboratory to the
testing field – it completed a high-altitude launch
from start to finish with all objectives met or exceeded.
This test at Florida's Eglin Air Force Base included deployment
of its fins and wings and an in-flight start of the engine.
After successfully navigating through a series of checkpoints,
it proceeded on to the intended target.
Spotlight: New Employees
||Wayne White, Quality Control Technician
Wayne has joined APT as a quality control technician. He
has 20 years experience in quality assurance working for
companies such as Ensign Bickford (now Dyno Nobel) and Cuno
Filtration. In this position, Wayne will hold direct responsibility
for assuring that our products fully meet our customers'
quality requirements. In addition, Wayne will work with process
documentation and the creation of work instructions.
||Rich Perry, Manufacturing Technician
Rich brings with him many years of experience as a manufacturing
technician and lab manager for companies such as JDS Uniphase
and Hamilton Standard. He is a specialist in small part assembly
and will be coordinating our assembly department where we
put together our many filter assemblies and chromatography
Expanding the Range of Our Filtration Capabilities
APT Forms Partnership to Develop Laser and Electron Beam Drilled
Porous Technologies is dedicated to becoming the best single-source
supplier of filter media and related products. Not only is
our goal to produce the highest quality parts in the industry,
but also to offer alternatives to our customers that have
special needs and requirements. In an effort to further expand
our current product lines, APT has partnered with an outside
company. Together, we have developed a proprietary filtration
alternative that will add a new dimension to our current
capabilities and provide new alternatives and solutions to
separation applications. The result is the addition of cost-effective
drilled metal filters to our catalog. This new product line
can accommodate almost any metal required for an application.
In addition to standard materials, such as stainless steel,
titanium and nickel, we can also work with more exotic materials
such as tantalum, molybdenum and stellite.
|Drilled Porous Media Examples:
|Std. Material Thickness
Sintered Porous Media is limited to a maximum of about 200µm
porosity. At these higher porosities, sintered porous metal
can exhibit some limitations in strength, requiring heavy wall
sections. We can now offer
substantially more strength with these solid metal drilled
filters, which are
capable of withstanding higher pressures with significantly thinner
material thicknesses. Minimum hole sizes start at .002" (50µm),
and there is virtually no limit to the maximum hole size we can
drill. The range of hole possibilities is dictated only by material
us at the Pittcon show to see samples of our new capabilities.
Laser and Electron Beam Drilled Porous Media can withstand
higher pressures with thinner material thicknesses.
ChemShow 2003 A Year-Ending Success!
We were excited to be an exhibitor at the 50th annual
ChemShow at the Jacob Javits Center in New York from Nov.
18-20. It was a pleasure to meet so many of our customers
face-to-face. We were also very happy with the response
to our porous metal tubes and the other products that were
on display at our booth. We look forward to serving the
many new customers we met at the show with the same level
of quality and customer service that we have been providing
to our existing customers.
Chromatographic Systems Benefit from Frits and Filters
and filters are porous metal products used in virtually
all liquid chromatographic (LC) systems. Their function is
to prevent unwanted particles from entering the LC system.
These particles may come from the sample, the solvent or
debris generated by the LC system itself (i.e. pump or injector).
Particles entering the LC system may lead to clogging of
capillaries, interference with the chromatography by changing
chromatographic parameters or disturbance of the detector
most important characteristic of a frit, besides the
diameter and the thickness, is the porosity. When considering
porosity, it is not only the average size of the pore
that is of interest,
but also the size distribution and the amount of pores
available. The size distribution should be a gaussian
function with narrow tolerances. At Applied Porous Technologies,
we continuously monitor our manufacturing
process and maintain strict control of the powders used
in our process in order to provide the tightest pore
addition to pore distribution, it is important to consider
the pore density, or number of pores available.
example, a frit with 2µm porosity and a surface
of 0.25". The theoretical maximum amount of pores
with 2µm average diameter would be about 5,000,000.
This frit would give you the highest possible flow
achievable. But, using standard bubble point testing,
a frit with just a few 2µm pores would be considered
frit with an extremely narrow tolerance. However, it
that this frit would provide the required flow. Careful
control of our powders and process allows Applied Porous
the best pore size distribution while maximizing flow
Applied Porous Technologies, we understand the needs
of the chromatography industry. We work closely
instrument manufacturers and column packing companies
to provide the best products available. Our employees
committed to continuously upgrading our products
through new product
development and process improvement. We are always
open to discussions and ideas on how to make our
products and services
better. Please call us at 860-408-9793 – we
