Hydrogen sulfide two-component EPA protocol gases
We offers hydrogen sulfide two-component gas mixtures as EPA protocols. These EPA protocol gas mixtures are instrumental in helping to avoid non-compliance fines and downtime caused by inaccurate instrument calibration. Air Liquide’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. A Certificate of Accuracy is provided with each cylinder.
CEM DAILY STANDARDSTM
Hydrogen sulfide gas mixtures are also manufactured as CEM DAILY STANDARDS and used in applications where the use of EPA protocol gases is not required. Zero blend tolerance is available as a result of our proprietary ACUBLEND (TM) technology, so that multiple cylinders that exhibit identical concentrations may be ordered. This minimizes the need to recalibrate each time you change out a cylinder.
