The Company
| 1935 | GOW-MAC Instrument Co. formed by Mr. William Gow and Mr. James McFadden to exploit an automotive engine analyzer developed by Mr. Gow. This analyzer utilized a thermal conductivity detector (TCD) and essentially measured the carbon dioxide content of the exhaust gas. This development leads to the manufacturing of various binary gas analyzers; e.g., air in H2, natural vs. manufactured gas, etc. The Company supplies analyzers to the U.S. Navy During World War II. |
| 1942 | GOW-MAC incorporates in New Jersey |
| 1946 | Gow leaves the company. McFadden continues manufacturing instruments and thermal conductivity cells |
| 1950 | Firm outgrows its plant in Newark, NJ and moves to Madison, NJ |
| 1959 | The need for TCDs increases due to the development of a new analytical technique called gas chromatography (GC). GOW-MAC becomes, and still remains, the major supplier of TCD's and detector elements (filaments) to the major manufacturers of GC's throughout the world. |
| 1969 | Firm adds to its instrument family by introducing its own line of gas chromatographs into the world marketplace. The Model 69-100 becomes the first in a long line of low cost, easy to use, quality GCs - a tradition that continues to this day. |
| 1978 | Firm expands and moves from Madison, NJ to Bridgewater, NJ |
| 1989 | Introduction of our patented Discharge Ionization Detector (DID). This detector revolutionizes the gas industry as a universal, non-radioactive detector capable of performing trace gas impurity analyses in the ppb range. The detector, when combined with the GOW-MAC Series 590 GC, becomes the industry standard. |
| 1993 | GOW-MAC acquires the assets and personnel of the Middlesex Service Center, a division of Linde, U.C.C. (now Praxair). The acquisition allows us to provide complete turnkey systems and analytical solutions for bulk, specialty and electronic gas systems. |
| 1994 | Firm relocates from Bridgewater, NJ to a new facility in Bethlehem, PA |
| 1997 | Introduction of our first fully digital GC, the Series 816. The GC combines the industry's leading digital GC platform with GOW-MAC's advanced detector technology. |
| 1997 | Acquires the assets of Olin Instruments, a division of Olin Corporation (Stamford, CT). GOW-MAC now offers its customers moisture analyzers for liquids and gases, and process GCs for water and air analysis. |
| 2000 | Opening of GOW-MAC Instrument Co. - Taiwan sales office in Taipei, Taiwan. |
| 2004 | Company adds a new line of gas analyzers, the 200 Series. These analyzers are specifically designed for the determination of impurities in beverage-grade CO2; i.e., aromatic hydrocarbons, BTEX, acetaldehyde, and sulfur. |
| 2005 | The 1000 Series line of trace gas analyzers for N2 in Ar, N2 in He, and H2O in Ar introduced. |
With its eye on the future, GOW-MAC continues to develop innovative detectors and gas analysis instruments for our customers and their always demanding, ever changing applications.
