VICI AG International

Dynacal permeation devices are small, inert capsules containing a pure chemical compound in a two phase equilibrium between its gas phase and its liquid or solid phase.

At a constant temperature, the device emits the compound through its permeable portion at a constant rate.

Devices are typically inserted into a carrier flow to generate test atmospheres for calibrating gas analyzer systems, testing hazardous gas alarms, or conducting long-term studies of effects on materials or biological systems – in short, any situation requiring a stable concentration of a specific trace chemical.

VICI permeation devices offer the following advantages over bottled standards:

  • Use pure substance in an inert matrix
  • Substances available which will not be offered in gas cylinders
  • Precise concentrations
  • Easily generated with NIST traceablity using established EPA and ASTM protocols
  • Removal and/or addition of a single component is simple
  • Wide range of concentrations easily generated by varying the dilution flow rate and/or the set point temperature
