Hydrogen Fluoride (HF) Monitoring in Air - Metal - Aluminium

Hydrogen Fluoride (HF) is a colorless gas that is used extensively in industrial applications. Fluoride monitoring is especially needed for aluminum plants that need to convert HF into fluorine for use in their processes. Any HF that escapes is a cost to the plant, so an HF analyzer is essential to keep track of and prevent the losses.

An instrument that uses a tunable diode laser, such as LasIR  from Unisearch, makes a perfect HF analyzer. When calibrated for fluoride monitoring, LasIR is able to provide continuous updates on the concentration of the gas in a given area. Features of LasIR fluoride analyzer include:

  • Reliable, accurate data output
  • Quick response to changes in compound concentration
  • Gas-specific sensor adjusted especially for fluoride monitoring
  • Easier maintenance and operation compared to a conventional HF analyzer
