Atomic Spectroscopy: Technique of Paramount Credence

Abstract

Analytical technique is can be defined as a means to verify the chemical or physical property of a matter. In actual practice, there are extensive assortment of techniques ranging from simple ones like sample weighing to sophisticated methods using highly dedicated instrumentation. The most primordial technique is the classical method like gravimetry (based on weight measurement), titrimetry (based on addition of a solution to sample solution). Spectrochemical methods are based on the measurement of spectrum of the samples using different instruments. Electroanalytical methods utilize the potential or current of a electrochemical cell for determination of sample concentration. Chromatography is a separation based technique used to isolate the analyte from the other species to enable interference free determination. 1 Spectrochemical methods depends on spectroscopy which is the study and measurement of the spectrum produced upon interaction of sample with electromagnetic (EM) radiation as function of frequency or wavelength of radiation. There are diverse forms of spectroscopy namely acoustic resonance (Cost effective spectroscopy technique in acoustic region, mainly ultrasonic & sonic regions), X-ray photoelectron (relies on diffraction patterns created while X-rays pass through crystalline materials), circular dichroism (helps in differentiating left & right circularly polarised light by sample), Ultraviolet-Visible (UV/Vis) Spectroscopy (probing the electronic structure for identification of compounds), NMR Spectroscopy (measure magnetic fields around nuclei using radio waves), Infrared Spectroscopy (IR region of EM radiation is used), Raman spectroscopy (for identification of molecules based on
