The story of PAC is a story of synergy — of a group of long-established scientific companies with complementary technologies and philosophies coming together at the beginning of this millennium to create a powerful, innovative company that leads the industries it serves in laboratory and process analytical solutions and advanced techniques.
The Petroleum Analyzer Company, L.P. — or simply PAC —is today a dominant 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, fuels composition, and laboratory automation.
PAC's history is a shared history that begins with the origins of its individual well-known and long-established leading product lines, including AC Analytical Controls, ISL, Antek, PetroSpec, Alcor, Walter Herzog, Precision Scientific, and PSPI. Herzog was founded in 1937; Antek in 1967; ISL, 1975; AC in 1981; but more important than the founding dates of the individual members of the PAC family 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, and AC joined PAC in 2006. The contribution that all of these separate brands brought to the PAC entity was and is enormous. Each company individually has for years been the backbone of best-in-class laboratories around the world, providing the basis for breakthrough product and process development in its particular area of expertise. They have been the enabling technology behind innovation in industries such as refinery, petrochemical, biofuels, environmental, food and beverage, pharmaceutical, and more.
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, and providing process and applications knowledge in every language that our customers speak.
