Established Players in the GC Industry

Falcon Analytical has been in business as a WV Limited Liability Corporation since 2007.

Our only business is serving refining, petrochemical, chemical and upstream customers with ultrafast gas chromatography and applications technology.

Our CALIDUS product was awarded two US patents. One provisional US patent is pending and two more patents are in development.

Our applications installed to date mirror our targeted customer segments and much more. We like to say from the winery to the refinery to the wellhead and everything in between.

Installation That is Not Location Specific

  • Using CALIDUS with an autosampler makes a fine lab instrument.
  • Using our Process Analyzer Enclosure CALIDUS is an awesome fast process GC.
  • The size, weight, utility gas and power consumption characteristics of CALIDUS enable the GC to be an excellent transportable GC.

Falcon's Authored ASTM Method

Our D7798 method is 2-3 times more precise than the older D2887 (equivalent) with no bias, enabling far more precise control for fuel production.

D7798 analysis time is <5 minutes, 2-7 times faster than any version of D2887.

CALIDUS is the only GC fully capable of running the ultrafast D7798 method and achieving these extraordinary results.

Outstanding Achievement Recognition

The State of West Virginia has awarded Falcon Analytical 15 Governors Commendations for Excellence in Exporting. Each award is for a new and distinct destination nation.

The US Department of Commerce has awarded Falcon Analytical the President’s “E” Award for Export Excellence.

For 2016 Dow Chemical and Falcon Analytical were joint finalists for “R&D” magazine’s R&D 100 Award and the UK’s “IChemE” award. These two awards are for significant contribution to the sciences, in this case chemical related science.

Dow and Falcon submitted a joint entry that included the Dow Chemical marker, Accutrace S10, that can be detected in fuels at 250 ppb levels by CALIDUS GCs.

Falcon Experience

Falcon has been in business since 2007 as a distributor and subcontract manufacturer of gas chromatography equipment.

We are owned in part by a larger business entity, Appalachian Electronic Instruments, Inc., a Class C corporation for more than 60 years.

Falcon has 8 specialized gas chromatography employees, supported by 50 AEI manufacturing employees, who build all of the CALIDUS GC hardware, in a 55,000’ square facility on the same industrial site where Falcon is located.

This gives Falcon deep capabilities for custom engineering and manufacturing as projects require. Falcon has the capacity to produce up to 500 CALIDUS ultrafast GCs per year without expanding staff.

Customized Customer Applications

CALIDUS ultrafast gas chromatograph installed base has grown to over 200 units since formal introduction in January 2010.

  • The first commercial customer was Dow Chemical followed shortly by Chevron.
  • About 25% of the CALIDUS GCs installed are applied in simulated distillation for fuel properties.
  • About 25% are deployed for natural gas composition measurement, from fixed gases up to C12.
  • About 25% are used in transportable fuel marker applications for fuel tax fraud detection.

The balance of the installed CALIDUS GCs are deployed in a variety of applications. For many of these applications the customers found it difficult to get any other supplier to help:

  • Acrylonitrile production (3 systems)
  • Propylene oxide production (one pilot plant)
  • Oligomers of propylene production (3 systems)
  • Water treatment chemicals production (1 system)

Each of the above are process installations. A 5th challenging process installation is for a gasoline blender at Chevron.
