Multi-parameter flame photometer Heavy Metal Detection/Flame photometer with K, Na, Li, Ca, Ba.
Flame photometry is the simplest of analytical techniques based on atomic spectroscopy. In this case, the sample containing metallic cations is inserted into a flame and analyzed for the amount of radiation emitted by the excited atomic or ionic species. The elements, upon receiving energy from a flame, generate excited species that, upon returning to the ground state, release part of the energy received in the form of radiation, at characteristic wavelengths for each chemical element. The flame photometer is the equipment used to perform different types of laboratory analyses. The product is always used on a large scale and, therefore, is essential for several sectors.
Despite the simplicity of the technique, several important concepts are involved in the development of experiments using flame photometry, from the principles of spectroscopy to statistics in data treatment, including sample preparation and elimination of interference. The manipulation of chemical elements requires a series of equipment suitable for this function, in order to promote the precise results expected and the safety of the operators, thus, in many cases the use of the flame photometer is applicable.
The flame photometer is equipment to analyze the proper dosage of some specific reagents contained in samples, Sodium (Na) and Potassium (K), and it can also include Calcium (Ca) and Lithium (Li). This observation occurs through the colors that each chemical element is capable of emitting when in contact with a non-luminous flame. Flame photometer for applications in food, cellulose, whey, beverages, soil, ore, human saliva, vinasse, and fuels.
Flame photometer is a relative measurement of the instrument, the concentration value of the sample under test conditions in the same relative value of the concentration of the standard solution.
So before the test, you must first prepare a set of corresponding standard solutions.
Then the calibration operation, the manual or the standard curve by the instrument, is the last to be tested on the test sample, to obtain the concentration value or other data required for calculation.

Flame Photometer Working Principle
Students perform salt analysis in an Inorganic chemistry laboratory which is also known as anion & cation detection. We qualitatively test different types of alkali and alkaline earth metals in the flame of colors. In a famous flame reaction, we identify the color of the flame as atoms that release energy Like sodium atoms flames are yellow. The intensity of a flame is directly proportional to the solubility atoms in the solution.
Flame Photometer works on the principle of emission spectroscopy as it utilizes the flame generated by supplied gas.
Heated flames initiate the alkaline earth metal atoms, & these atoms absorb energy from an initial energy level. When this energy level reaches to normal energy level it is compulsory to release energy. Released energy has spectral characteristics that have a certain wavelength.
