Calibration and special mixtures  [ Return towards  Laboratories and analysis  ]

We produce all categories of customized mixtures:

  • mixtures of 2 to 40 components,
  • concentrations ranging from % to ppb,
  • blending tolerances ranging up to 1% relative,
  • calibration uncertainties ranging up to 0,1% relative.

To select the proper mixture is due to define:

  • application - to choose the right mixture category,
  • components and expected concentrations,
  • carrier gas,
  • cylinder size,
  • quality documentation required.

The mixture category depends of blending tolerance and calibration uncertainty.

Blending Tolerance BT - maximum difference between the required nominal concentration and the realised concentration. This property is related to production technology.

Uncertainty U - maximum difference between the concentration achieved and the true concentration of the mixture. This property is related measuring technique.

All these mixtures are delivered with analysis certificate as per ISO 6141 standard, giving the details of:

  • the mixture components,
  • blending tolerances,
  • uncertainties,
  • shelf life,
  • traceability information.
