An Industry Leader for over 85 years


In 1927 MATHESON Gas Products became the first company to offer a reliable source of high quality scientific gases and equipment. From the start, MATHESON asserted its leadership by understanding specialty gas applications and providing products specially designed for these applications. Some of MATHESON's more notable accomplishments include the development of the lecture bottle, now used by virtually every major college and university in the world, and the supply of ultra pure gases that served as standards for the first gas chromatographs.

MATHESON's gases also helped forge the most important tool of our era, the integrated circuit. From the early days of the transistor, MATHESON was there providing the arsine and phosphine that made production possible. As transistors gave way to complex semiconductor chips, MATHESON provided the world's first commercially produced silane, an accomplishment that earned the industry's prestigious "SEMMY" Award.

In 1999 MATHESON Gas Products merged with Tri-Gas, Inc., to form Matheson Tri-Gas, Inc. This merger combined the analytical and semiconductor strengths of MATHESON Gas Products with the liquid/bulk and industrial cylinder and equipment capabilities of Tri-Gas. As a member of the Tokyo based Taiyo Nippon Sanso Corporation (TNSC), MATHESON is part of the world's fifth largest supplier of gases and gas handling equipment.

Research & Development

At MATHESON, service does not end at the customer's receiving dock. Assisting in process and product development is an essential part of the MATHESON offering. By beta-site testing new products prior to introduction, MATHESON maintains a leadership position in providing a global offering of field proven specialty gas and equipment solutions. In addition, a staff of scientists and engineers continually interacts with customers to improve material specifications and suggest process improvements. This results in MATHESON customers achieving the greatest benefit from MATHESON capabilities.

The MATHESON charter is to develop the highest purity materials with accurate specifications for metallic and particulate impurities and the specialized gas handling equipment to ensure purity. Focusing on developing advancements in new materials and analytical and production techniques, MATHESON delivers statistically proven process control, state-of-the-art packaging and the ultimate in analytical procedures and equipment.

MATHESON research has led to the continual introduction of new products such as:

  • ULTIMA™ Gases: 99.9999+% purity and guaranteed low metals content.
  • State-of-the-Art Metal Precursors such as tungsten hexafluoride and dimethyl aluminum hydride (DMAH).

Gas Applications Center

The Gas Application Center (GAC) focuses on solutions for industrial gas applications, particularly in food processing, primary metals production, and fabrication. The MATHESON GAC is an extension of the Yamanashi Facility for Gas Applications Research and Development, at our parent company, Taiyo Nippon Sanso Corporation.

Commitment to Quality through Innovation

As businesses, markets, or products reach maturity, successful companies find new innovations in products, services, and processes, providing for a continuous pipeline of innovations that leapfrog the competition and provide quality products to customers. 

Multi-functional Innovation Teams are now an important part of the company culture at MATHESON. These teams regularly review trends in the specialty gas market, as well as other markets, with an eye toward delivering the most innovative and highest quality products. MATHESON's charter is to be a customer-focused, cost-conscious, stable company that uses its strength in quality to drive business success.
