Iran-Made Device Measures Concentration of Water Pollutant
“Static spectrometer device in addition to the common uses of an optical spectrometer, which measures the absorption and transmission of light through liquid and transparent materials, can also be used as a water and sewage analyzer,” said Maryam Zare’, the managing director of the knowledge-based company.
“This product has its own software and is designed to detect and measure the concentration of pollutants and various water parameters,” she added.
Noting that the device is produced in two models of ISTA-UV and ISTA-Vis, Zare’ said, “This device is a light and compact single-beam optical spectrometer that can be used in a desktop or portable form by the users in laboratories and operational fields.”
“By adding special reagents to water and changing its color as a result, the static spectrometer can measure the concentration of various parameters in water and wastewater like COD, ions such as nitrate, nitrite, phosphate, etc., and metals like iron, manganese and zinc,” he added, stating that the CIELAB method can also be used in this spectrometer to determine the color and color combinations of materials.
A spectrometer is a scientific instrument used to separate and measure spectral components of a physical phenomenon. Spectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed. In visible light a spectrometer can separate white light and measure individual narrow bands of color, called a spectrum.
A mass spectrometer measures the spectrum of the masses of the atoms or molecules present in a gas. The first spectrometers were used to split light into an array of separate colors.
Spectrometers were developed in early studies of physics, astronomy, and chemistry. The capability of spectroscopy to determine chemical composition drove its advancement and continues to be one of its primary uses.
Spectrometers are used in astronomy to analyze the chemical composition of stars and planets, and spectrometers gather data on the origin of the universe.
Examples of spectrometers are devices that separate particles, atoms, and molecules by their mass, momentum, or energy. These types of spectrometers are used in chemical analysis and particle physics.
