The comparison of emission intensities of unknown samples to either that of standard solutions, the alkali and alkaline earth metals. Flame photometer has both quantitative and qualitative applications. Flame photometer with monochromators emits radiations of characteristic wavelengths which help to detect the presence of a particular metal in the sample. This help to determine the availability of alkali and alkaline earth metals. Simple direct analysis procedure calcium, magnesium, in test solution flow injection analysis using flame atomic absorption spectroscopy or flame photometry designed using a well-mixed dilution chamber to increase calibration range. Analysis results real samples correspond to those found in the flame batch atomic procedure. Using the dilution chamber allows possibility of calibration using a dilution profile a single concentrate standard for each element and an empirical dilution equation that can be used to all elements are defined in each sample.
