Hi, I have a spectrometer and software for analyzing gas tubes and light spectra. I would like to include flame spectroscopy. I am teaching a camp this summer where i need my materials to be mobile. What is the smallest set up i can buy and what kind of materials will i absolutely need? Can i just use camping stove gas like butane or propane? Can i just place the salt powder over the flame and point the spectrometer at the flame?
