Sulphur dioxide pure gas with purity up to 99.9% to be used in a variety of applications, including chemical synthesis, pesticides and disinfectants. Sulphur dioxide is also used as a component in various gas mixtures, in a variety of balance gases primarily used in environmental monitoring. When a smaller quantity of gas is warranted, We delivers sulphur dioxide mixtures in Mini-Mix (TM) transportables, designed specifically for industrial hygiene and safety and laboratory applications.

EPA protocol gases

We offer sulphur dioxide two-component gas mixtures as EPA protocols. These EPA protocol gas mixtures are instrumental in helping you avoid non-compliance fines and downtime caused by inaccurate instrument calibration measuring sulphur dioxide emissions. Our supplier’s specialty gas manufacturing facilities are registered participants of EPA’s Protocol Gas Verification Program (PGVP). Protocol standards are dual-analyzed, and for each reactive component, two separate analyses are performed and analyzed directly against metrology institute standards to determine the concentrations. Certificates of Accuracy are provided with each cylinder. In addition, sulphur dioxide is also offered as part of multi-component EPA protocols to meet any specification.

CEM DAILY STANDARDS (TM)

Sulphur dioxide gas mixtures manufactured as CEM DAILY STANDARDS are used in applications where the use of EPA protocol gases are not required. Zero blend tolerance is available as a result of our proprietary ACUBLEND (TM) technology. As a result, multiple cylinders exhibiting identical concentrations may be ordered, minimizing the need to recalibrate each time you change out a cylinder. These mixtures are available in two-component and multi-component variation.
