Atomic Spectroscopy
It deals with the study of electromagnetic radiation absorbed and emitted by atoms .The unique elements have characteristic spectra, atomic spectroscopy, specifically, a mass spectrum is applied for the determination of elemental compositions.
Mass Spectroscopy
Mass spectrometer is an analytical technique that measures the mass-to-charge ratio of ions. It is used in many different fields and also applied to pure samples as well as complex mixtures. The instrumental method for identifying the chemical constitution of a substance by means of the separation of gaseous ions
Raman spectroscopy
It is a spectroscopic technique based on inelastic scattering of monochromatic light, usually from a laser source. Inelastic Scattering of monochromatic light means that the frequency of photons in monochromatic light changes upon interaction with a sample.
Photo thermal spectroscopy
Photo thermal spectroscopy is a group of high sensitivity spectroscopy techniques which is used to measure optical absorption and thermal characteristics of a sample. The basis of photo thermal spectroscopy is the change in the thermal state of the sample resulting from the absorption of radiation
X-ray photoelectron spectroscopy
X-ray photoelectron spectroscopy also is known as electron spectroscopy for chemical analysis. X-ray photoelectron spectroscopy is used to determine quantitative atomic composition and chemistry. This is a surface analysis technique with a sampling volume that extends from the surface to a depth of approximately 50–70 Å
Ultraviolet–visible spectroscopy
UV-visible spectrometers can be used to measure the absorbance of ultraviolet by a sample, either at a single wavelength or perform a scan over a range in the spectrum. Ultraviolet region ranges from 190 to 400 nm and the visible region from 400 to 800 nm.
Infrared Spectroscopy
Its deals with the infrared region of the electromagnetic spectrum that is light pass with a longer wavelength and lower frequency than visible light. It is mostly based on absorption spectroscopy.
