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?
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.
