Metals in solution in flame emit light at strong emission wavelength lines, which can measure calcium, sodium, potassium, and low-molecular-mass-metal concentration {atomic emission spectroscopy} {emission flame spectroscopy}. Sample can be in graphite furnace, carbon-rod analyzer, boat, cup, or atomizer. Premixing is in mixing chamber or by baffles. Flame temperature is low enough not to ionize atoms. Flame excites electrons. Atomic emission detects emission-line intensity. For atomic emission, concentration must be 1%.
