Kin-Tek's new Trace Source permeation tubes are used to blend gas calibration standards needed for air analysis for many hazardous air pollutants (HAPs). More than 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 vapor flow that is used to dynamically blend low-pressure gas mixtures. Emission flow measurements are traceable to NIST through fundamental measurements, including weight change and temperature. Mixing the emission flow with a traceable flow dilution gas creates a traceable mixture.
FlexStream and AutoBlend gas-standards generators provide controls required to blend traceable gas mixtures using Trace Source tubes.
