Some Practical Applications Of Spectroscopy You Might Want To Know

Spectroscopy uses radiation and the electromagnetic spectrum to penetrate into the layers of different forms of matter and analyze their condition. The results are based on measurements and precision that are later converted into test reports to analyze our surroundings. From agriculture to medicine, this technique has a wide range of applications and is used in almost every discipline in varying forms. Over time, the wavelengths and frequencies were altered to reach the atomic level of any form of matter and achieve more precision in the results. Today, this has made the technique quite popular in numerous domains. Here are some practical applications and uses of spectroscopy.

Practical Applications

1. Geology

The first and most important application of spectroscopy is the study of different surfaces and rocks by inducing electromagnetic spectrum into the layers. From analyzing the features of the terrain to determining their mineralogy, spectroscopy can unravel distinct characteristics of the earth. In some studies, radiation is used to place hydrocarbons in the sea and water columns, which are then applied in the analysis of micro-organisms on land and in water. Basically, the differentiation between minerals is made easier with the electromagnetic spectrum, which also helps identify different forms of complicated structures.

2. Environmental Analysis

Another useful application of spectroscopy and radiation is the study of the environment and relevant changes on a daily and annual basis. Ultraviolet and visible spectroscopy have been in use for a couple of years to determine environmental conditions. Typically, the main study involves testing water samples and properties using colorimeters and portable kits. Atomic absorption is another way to detect the condition of solids and water, with metal detection being the primary task. Another form of spectroscopy technique is electrothermal atomization, which is used to test semi-solid samples. Certain solid materials are also examined based on their atomic composition using X-ray techniques.

3. Forensics

The forensics department in crime branches uses spectroscopy to find proof and trace tiny particles to gather evidence at crime scenes. A sub-branch called ​​micro-spectrophotometry is often used at the crime scene to detect paint, hair, cloth fibers, and other tiny particles that are invisible to the naked eye. As suggested by the equipment specialists at, the investigators prefer a wireless spectrometer over other devices to gain more accurate results and analyze particles with precision. The composition and nature of the tiny particles are studied using infrared light and varying frequencies, which are later transformed to reveal the colors and enhance their visibility.

4. Medical Field and Hospitals

This technique also plays a vital role in detecting toxic components in blood and disinfecting operation rooms in hospitals. Spectroscopy has a distinct role in neurology as it helps detect brain defects through MRIs and CT scans. These devices emit radiation that helps pick neurological conditions like aneurysms, tumor growth, strokes, and vascular formations at a greater depth. In turn, it makes the diagnosis more accurate and increases the success rate of the treatment. New technological advancements are incorporating radiation and some forms of spectroscopy to detect health issues and treat them at the earliest. For instance, an app was developed to diagnose eye cancer in infants using reflection and scanned images.

5. Astronomy

This technique is also widely used to spot comets and study galaxies using the electromagnetic spectrum. The material analysis and composition of the comets and other celestial bodies are studied to determine our solar system’s configuration and nature. Radio waves, visible light, infrared, X-rays, and UV rays are used to study celestial bodies and the matter floating in galaxies. Along with the structural and material composition, the density, distance, temperature, luminosity, and chemical composition of the bodies are studied too. Galactic nuclei, nebulae, and planets are some other bodies actively studied by astronomers using radiation, radio interferometry, and optical spectroscopy.

6. Agriculture

Today, spectroscopy is also widely used in agricultural and farming domains due to its ability to grow and harvest healthier crops and produce. Since agriculture and crop production can have a negative impact on the environment, radiation specialists recommend using this technology to diminish the effects while encouraging the growth of healthier crops. This technique is used to monitor the crops right from the initial stages until they are ready to be harvested. Furthermore, the amount of nitrogen received by the crops is also analyzed and the supply is redirected according to the needs. Lastly, the number of fertilizers and pesticides sprayed on the food is also supervised using radiation technology.

Spectroscopy has turned into a valuable analytical tool that has helped many fields to date. The rapid increment in the technological implications is further making tasks easier and helping produce more accurate results in each industry. Some advanced tools are also used at a later stage to develop high-resolution images of the new discoveries.
