Example of main emission line (or band) from sulfur, phosphorus, sodium and potassium between 350 and 800 nm.

Flame spectroscopy presents many advantages:

  • The measure is instantaneous: each time toxic molecules are sampled in the flame, it reacts immediately.
  • All elements can be simultaneously detected because they emit different colors.
  • The response time is very fast
  • The “return-to-zero” time is very fast
  • There is no memory effect. Even if you detect a high concentration, the sensitivity for all detectable elements will recover a few seconds after.
