Gas Standards for Formaldehyde

Wed, 01/04/2012 - 11:57am

Trace Source™KIN-TEK’s Trace Source™ permeation tubes are used to dynamically blend trace concentrations of formaldehyde in air. According to the company, the tubes are characterized by:

  • Mixtures can range from low ppb to over 500 ppm.
  • Alpha-polyoxymethylene, a high-purity formaldehyde polymer, decomposes to maintain a stable vapor pressure of formaldehyde and a stable emission rate of formaldehyde. 
  • Formaldehyde emitted from the tube is mixed with a known flow of zero air to form the trace concentration gas standard.
  • 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.
