Our Capabilites

We believe in working closely with our Partners and go out of our way to address all concerns and questions pertaining to specialty gas mixtures and specialty gas applications. By working together to understand all the needs and desires of each Partner, CSI Gas will establish an in-house “Port Folio” of all mixtures and requirements for each operation and location.

The Folio also list usage rates, volumes, pressures, and the Dewpoint of each mixture. Knowing the desired accuracy for each mixture. Whether it is a Primary Mixture with a +/- 1% Analytical Accuracy or Certified Mixture with a +/- 2% Analytical Accuracy. A Custom Certified mixture or a Gravimetric only Certified mixture. The Folio helps eliminate errors when ordering a mixture at a time of need. Each mixture has an Item number associated with it to eliminate key stroke errors or simply entering the wrong information. If a mixture needs to be altered, we will note the date and time of the change. We can always return to the date, which the mixture was modified.

The Port Folio references:

  • the correct cylinder and valve,
  • the components of each mixture,
  • the concentration of each component,
  • the analytical and blend tolerances, and
  • the makeup whether it be a liquid or vapor and how it is produced and reported in Mole, Weight, or Volume %.
