Flame Photometry

1.0 INTRODUCTION shine p zestyometry, also referred to as flare pinchic outpouring spectrometry is a quick, stinting and simple way of detecting traces of miscellany ions, primarily Sodium, Potassium, Lithium, Calcium, and Barium, in a concentrated solution. The process is an annexe of the principles used in a cauterize test, with the main differences having to a greater extent precision in the results, and the use of more advanced technology. This makeup 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 touchstone the spectral intensity of lines produced by metals usher in in ionic compounds. Measuring the flame emission of solutions containing the metal salts is do to perform a quantitative analysis of these substances (Internet 1). 2.2 The electrons of an fraction pull through in different energy levels. When energy is added to an share in the form of l ight/heat/electrical energy, the pinch becomes excite and electrons begin to jump to higher energies (Figure 1). There are devil states that an atom can exist - an huffy state and a base (natural) state. The ground state of an atom is when the electrons are in their lowest 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 then(prenominal) emit light of a characteristic wavelength as the excited atoms decay to the unexcited ground state (Internet 10). Fig.1 2.3 Flame photometers give-up the ghost by vaporizing metallic salts in a! truly hot flame: when a solution of a salt, such(prenominal) as sodium 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 actually small proportion of these atoms... If you want to snuff it a wide-cut essay, order it on our website: BestEssayCheap.com
