ABOUT
ASI
-
ASI
manufactures a broad range of instruments and components
for High Pressure Liquid Chromatography (HPLC). While some
of our products may appear rather routine at first glance,
ASI
instruments and components incorporate technology
which is totally unique in the industry. The approach to
product development at
ASI
has always been to “build a better mouse trap” to solve
some of the most vexing problems that chromatographers face.
Our solutions include:
ASI
Self-priming Check Valves,
HyperShear™
Static and Dynamic Mixers, and fluid resistor based
QuickSplit™
Fixed and Adjustable Flow Splitters. Whatever the
product, the final test is customer satisfaction, so we
go to great lengths to insure all
ASI
products work as advertised.

We can also apply our engineering and manufacturing expertise
to develop custom products to meet your specific
needs.
ASI
has worked with, and designed OEM products for most major
HPLC manufacturers. Please let us know if we can provide
components or subassemblies for your next HPLC project.
Engineering Expertise
-
If the design is not correct to begin
with, then even the best manufacturing capability in the
world can do no more than produce a well made product that
doesn’t work. At
ASI,
we apply a rigorous engineering analysis to our products
before they go to the prototype stage. For our check valves,
this entails stress and deflection analysis of critical
components such as the seat, gaskets, and valve casing.
A fluid flow analysis is then performed to make certain
that the pressure drop across the valve is within proper
limits. Finally, a tolerance study is performed on the design
to insure that the parts fit together (it is here where
90 % of all designs fail!).
Once the prototype is built, we test it to verify that the
performance matches the theory. Next, we build several production-like
units that allow us to prove manufacturability, reliability,
and most important of all, the consistency of the product
performance and reliability over the specified range of
manufacturing tolerances.
Manufacturing Capabilities
|
Modern, State of the Art
Manufacturing Facilities |
- Good design is the essential starting point for performance and reliability, but a good design is use-less without the manufacturing capability to execute it properly. For this reason, we have invested much time and
money into our computer controlled machining centers, inspection equipment, and the experts to set up and operate this equipment properly.
|
- Many of our products are manufactured with dimensional tolerances that are equal to 1/50 of the diameter of human hair. While these tolerances are often tighter
than our designs dictate, we believe that the
resulting improvement in reliability and
performance is well worth the added cost in
manufacturing.
|
Quality Control and Final Test
-
We believe it is not possible to manufacture
reliable valves or other fluidic devices without 100% inspection
of all critical parts. That is why we inspect every critical
dimension on every part that affects valve performance .
But even with all this inspection, we know we’re not perfect,
so every mixer assembly or check valve that we ship is first
subjected to a final test to prove that it performs properly
under pressure.
