Laser HCN Analyzers at a Composite Plant

← Back to Chemicals applications

In-situ laser gas analyzers for HCN measurement on a carbon fiber production line, with flange/purge kits and stainless steel mounting panels.

HCN on a carbon fiber line

In carbon fiber production, hydrogen cyanide can form during high-temperature processing. Because the gas is toxic, continuous monitoring matters for both process and safety.

Why in-situ laser measurement

Since TDLAS measures directly on the duct, it reduces the risks tied to a sample transport line and can respond quickly. Installation considerations include:

  • Flange and alignment conditions
  • A purge arrangement that keeps the optical window clean
  • Vibration and temperature effects
  • Mounting panels suited to the environment
