Spectroscopy has a wide area of application in many fields. Spectroscopy is based on the concept of Energy = frequency x Planck (E=ʎh) constant which is used to study matter. Spectrometry is the technique which is used to analyze the concentration of elements in the sample being tested. Our products are able to analyze carbon, aluminum, sulfur, gold, silver, magnesium, steel, alloys and many other elements. We can also calibrate our products to account for elements like oxygen which are present in many compounds by calibrating with a known sample.
Since spectroscopy can be applied to many applications, there are many different types which are applied according to their necessities. Spectroscopy measures the energy that is either emitted to radiated in the form of different wavelengths of the electromagnetic radiation which includes light, ultraviolet, x-ray and many others.
Some of the types of spectroscopy we offer are fluorescence spectroscopy, absorption spectroscopy, emission spectroscopy, optical emission spectroscopy, Fourier Transform spectroscopy, visible spectroscopy, ultraviolet spectroscopy, infrared spectroscopy and many others.
Absorption spectroscopy measures the change in intensity of light before and after the sample’s interaction with the light. It is heavily seen in laboratory settings when dealing with concentrations and in major experiments.
Atomic emission spectroscopy (AES) measures light that is emitted from flame excited samples. It is generally used in the chemical and biochemical industry used for quantitative analysis.
Atomic absorption spectroscopy (AAS) measures light that is absorbed due to lamp and atomization of excited samples. Generally, it is used to analyze solutions or solid samples for metals which account for more than 70 elements.
Atomic fluorescence spectroscopy (AFS) is the opposite to the absorption technique. In this case the light that is emitted is measured. It is not heavily used as the other techniques but is used when greater sensitivity is needed than absorption techniques can provide for example in heavy metals detection.
Fluorescence spectroscopy measures the change in the energy of the photons when the sample is exposed to high energy photons which results in the emission of lower energy photons by the sample. It is generally used in chemical, biochemical, medical, research and industrial fields.
Fourier transform infrared (FTIR) spectroscopy measures samples based on time/space domain measurements using Fourier transforms. It is the most versatile tool to analyze chemical bonds for many materials and compounds including polymers, paints, drugs, contaminants.
Optical emission spectroscopy (OES), plasma, spectroscopy & spark or arc emission all work on similar principle where either plasma, arc or spark is used to excite the sample by heating it and detecting the emitted spectrum.
Visible, ultraviolet, and near-infrared spectroscopy is generally combined together to measure gas phase samples for either absorption or emission spectrums. Visible, ultraviolet, and near-infrared can all be in the sample instrument or all the separate.
X-Ray spectroscopy uses x-rays to excite the lower orbital electrons to the outer orbitals and thus producing an emission or absorption characteristic that specifically identifies the elemental composition. The common technique used in laboratory and industrial applications is known as x-ray fluorescence spectroscopy (XRF).
Some other types of spectroscopy are visible, mass spectroscopy, scattering spectroscopy, Raman spectroscopy, nuclear magnetic resonance spectroscopy hardon spectroscopy, thermal infrared spectroscopy and many others.
