Absorptiometer

Absorbtiometer: Definition and Application

An absorbentiometer is a device that is used to measure the absorption of radiation of a specific wavelength by a substance. The term "absorbtiometer" comes from the Latin word "absorptio" - absorption and the Greek word "metreo" - to measure.

The fundamental principle of operation of an absorptiometer is to measure the intensity of radiation before and after passing through the substance being measured. The measured difference shows how much radiation was absorbed by the substance, which allows its optical density to be determined.

Absorbtiometers are used in various fields of science and technology, including photometry, spectroscopy, chemistry and medicine. In medicine, for example, absorption meters are used to measure the concentration of hemoglobin in the blood and diagnose diseases associated with its imbalance.

In chemistry, absorption meters are used to determine the concentration of a substance in a solution. They can also be used to measure the light absorption of various materials such as glass, plastic and metals.

In photometry, absorption meters are used to measure the intensity of light passing through a photosensitive material, such as in photography and cinematography.

The measurement accuracy of absorption meters depends on a number of factors, including the quality of the optical components, the wavelength of the radiation, the optical density of the substance being measured, and other factors.

In conclusion, an absorbentiometer is an important device that finds application in various fields of science and technology. It allows you to measure the absorption of radiation by a substance and determine its optical density. Thanks to the absorption meter, we can better understand the world around us and create new technologies to improve our lives.

Absorptiometry (eng. absorption spectrometry, spectroscopy) is a branch of analytical chemistry that studies the absorption spectra of various substances in solutions.

Absorption methods are based on the ability of a substance to absorb light of a certain wavelength. In this case, a change in the energy of the molecules occurs, which is accompanied by the release of heat. As a result of this process, the substance goes into an excited state, which can then go into the ground state with the emission of a photon.

Absorption spectroscopy uses various physical principles to measure the absorption of light. For example, a transmission method may be used where the sample is passed through a beam of light. This method allows the measurement of light absorption in the wavelength range from a few nanometers to several micrometers.

Another method is the reflection method, where the sample is placed on the surface of a specular mirror. This method is used to measure absorption at wavelengths ranging from a few millimeters to several centimeters.

There is also an absorption method, which involves placing the sample in a chamber filled with gas or liquid. This method can be used to measure absorption over a wide range of wavelengths.

It is important to note that absorption spectroscopy is an important tool in various fields of science and technology, such as chemistry, physics, biology and medicine. It allows you to obtain information about the structure and properties of substances, as well as about the processes occurring in them.
