Question

Hii! I have a question: So the flame photometer uses a natural gas flame (1800 oC), what if it uses acetylene - nitrous oxide flame which is ~3000 oC, what would happen to the emission intensities?


Thanks!

Answer 1

It depends upon what atomic or ionic lines the photometer is looking at, and what is added to the flame. Generally speaking, a hotter flame will be brighter, but not at all wavelengths. Ion lines will tend to be favored over neutral atomic lines at higher temperature.
