Principle: A solution of the salt is aspirated into the LPG-AIR flame. The vapor takes up energy from the flame and emits the wavelength Characteristic color of the element being tested. The intensity of emitted light is proportional to the concentration of the metal Ion in the solution. This light is measured through a filter/detector/ amplifier combination. This being a comparator, known Standard solutions are to be used for calibration.
