Calibration Gas Mixtures Three Decisions Have to Be Made

DECISION NO. 1 THE RIGHT APPROACH Even a simple listing of mixture components can require decisions. Mixture accuracy, component compatibil i ty, background impurit ies and pressure levels are some of the factors to be considered. Matheson has the experienced personnel at each location to provide the right approach for your application.

DECISION NO. 2 THE RIGHT CYLINDER To many, this means only the material of construct ion or internal cylinder treatment. A t Matheson, this question means m u c h more. Safety, pressure-volume relationship, chemical proper­ties of the components, storage and portability, in addit ion to material of construction and internal cylinder treatment are all inter-related and vary with your requirements—Mathesons 30 years of experience in gas mixtures will provide the right cylinder decision.

DECISION N O . 3 THE RIGHT REGULATOR Matheson has more than 100 different pressure regulators f rom which to choose exactly the right regulator for your mixture. The selection of the wrong regulator can change your mix­ture by adding impurit ies and/or reducing component concentrations. Our experience takes the guess work out of regulator decisions.
