Flame Photometry

1.0 INTRODUCTION shine p eagerometry, also referred to as flare pinchic venting spectrometry is a quick, stinting and simple way of detecting traces of admixture ions, primarily Sodium, Potassium, Lithium, Calcium, and Barium, in a concentrated solution. The process is an flank of the principles used in a cauterize test, with the main differences having more than precision in the results, and the use of more advanced technology. This piece focuses on the theory, applications, limitations and abridgment of Flame Photometry. 2.0 EXPLANATION OF THEORY 2.1 A flame exposure meter is an peter used for step the spectral intensity of lines produced by metals usher in in ionic compounds. Measuring the flame emission of solutions containing the metal salts is through with(p) to perform a quantitative analysis of these substances (Internet 1). 2.2 The electrons of an fraction subsist in different energy levels. When energy is added to an share in the form of light/heat/ele ctrical energy, the pinch becomes frantic and electrons begin to jump to higher energies (Figure 1). There are devil states that an atom can exist - an frenzied state and a reasonableness (natural) state. The ground state of an atom is when the electrons are in their worst energy level.

The use of a flame photometer relies on the principle that a metal salt displace into a non-luminous flame will ionise, absorb energy from the flame and thusly emit light of a characteristic wavelength as the excited atoms decay to the unexcited ground state (Internet 10). Fig.1 2.3 Flame photometers usage by vaporiz ing metallic salts in a truly hot flame: wh! en a solution of a salt, such(prenominal) as nuclear number 11 is sprayed into the flame, the elements in the compound are part converted into their atomic state. Due to the heat energy of the flame a really small proportion of these atoms... If you want to snuff it a panoptic essay, order it on our website: OrderCustomPaper.com
