Permeation Tubes for Hazardous Air Pollutants

Kin-Tek (USA’s) new Trace Source™ Permeation Tubes are used to blend gas calibration standards needed for air analysis for many Hazardous Air Pollutants (HAPs). Over 80 HAPs are currently available in Trace Source™ tubes. Applications include formaldehyde, hydrazines, ethylene glycol, cresols, naphthalene, and 15 other compounds not available as ‘cylinder’ mixtures.

Trace Source™ permeation tubes emit a constant flow of vapor that is used to dynamically blend low-pressure gas mixtures. Emission flow measurements are traceable to NIST through fundamental measurements (weight change, temperature, etc.). Mixing the emission flow with a traceable flow dilution gas creates a traceable mixture.

FlexStream™ and AutoBlend™ Gas Standards Generators provide the controls required to blend traceable gas mixtures using Trace Source™ tubes.
