6400A Flame Photometer for Potassium and Sodium Analysis

The 6400A Flame Photometer is a laboratory analytical instrument designed primarily for quantitative determination of potassium (K) and sodium (Na) concentrations in liquid samples using flame emission photometry. The instrument introduces the sample into a flame, where potassium and sodium atoms emit light at characteristic wavelengths. The emitted intensity is measured and related to the concentration of each element. The system is suitable for clinical, pharmaceutical, agricultural, food, environmental, chemical and research laboratories. The 6400A family is specifically documented for simultaneous potassium and sodium determination.
