PAC - A Shared Synergy, a Shared History of Outstanding Innovation

The story of PAC is one of synergy — of a group of long-established scientific companies with complementary technologies and philosophies coming together to create a powerful, innovative company that leads the industry in laboratory and process analytical solutions and advanced techniques.

The Petroleum Analyzer Company, L.P. — or simply PAC —is a leading global provider of advanced analytical instruments for laboratories and process applications. With a product portfolio of over 200 instruments, PAC serves its customers with cutting edge technology and significant R&D resources to support its core technologies, including chromatography, elemental analysis, physical properties, ultrasonics, fluorescence, spectroscopy, and microscopy/video imaging.

PAC's history begins with the origins of its individual well-known and long-established leading product lines, including AC Analytical Controls, Cambridge Viscosity, ISL, Antek, PetroSpec, Alcor, Walter Herzog, Advanced Sensors, and Precision Scientific. PAC’s product lines were founded in:

However, more important than the founding dates of the individual members of the PAC team is the successful, innovative companies that each evolved into, and their roles today since becoming part of PAC.

PAC's story begins to truly gather momentum just before 2000, when ISL joined with Varlen Instruments to become part of PAC. Varlen Instruments dissolved and those subsidiaries, now part of PAC, included PSPI, Herzog, Alcor, and PetroSpec, which had all been acquired by Varlen during the 1980s and 1990s. Antek joined PAC in 2000, AC joined in 2006, Cambridge Viscosity joined in 2012, and Advanced Sensors joined in 2013. The contribution that all of these separate brands brought to the PAC entity was and is enormous. Each product line has a long history of developing best-in-class analytical instrumentation. They have been the enabling technology behind innovation in industries such as refinery, petrochemical, biofuels, environmental, food & beverage, marine, offshore, subsea, and pharmaceutical.

In the decade since PAC began its current phase of growth and expansion, the company has emerged as the global leader in its field. PAC customer support centers are found in key locations around the world, and the company is dedicated to its customers and their success, providing service and support on the local level.
