Absorbance &Concentration

When a beam of light passes through a light-absorbing substance (usually a solution), the solute absorbs the light energy and the intensity of the light decreases. Absorbance is a physical quantity used to measure the degree to which light is absorbed. Based on absorbance measurement is easy to implement and use, absorbance measurement is widely used in spectral measurement technology for liquids and gases, and can also be integrated into industrial applications and customer-focused tests. Absorbance spectroscopy can quantitatively identify substances or quantify the concentration of molecules in solution. The direct relationship between the absorbance of a solution and the concentration is known as the Lambert-beer law. A solution sample of unknown concentration can be measured using a spectrometer to calculate a matching curve of solution absorbance versus concentration by testing several sets of solution samples of known molar concentration.

Compared with the traditional experimental measurement of absorbance, the spectrometer test is simple and efficient, and the experimental results are accurate and reliable, which frees researchers from complicated experimental operations and reduces human error. The spectrometer is based on a modular design, so you can change the equipment layout according to constantly changing experimental needs; Interchangeable equipment layouts, escalating experimental operations and applications enable a various range of experimental applications now and in the future.
