Color spectrophotometry uses a light source to illuminate a sample with light across the UV to the visible wavelength range (typically 190 to 900 nm). The instruments then measure the light absorbed, transmitted, or reflected by the sample at each wavelength. Some color spectrophotometry has an extended wavelength range, into the near-infrared (NIR) (800 to …
Biochemical analyzer (BCA) is an analytical instrument used to measure various biochemical indicators of human blood. It can provide doctors and chemical laboratory personnel with testing data accurately and quickly, and plays an important role in monitoring bed diagnosis and chemical testing. The colorimeter is the core component of the biochemical analyzer. In traditional colorimeters, …
If you want to dive into colorimeters, we must first understand the colorimetric theory. Before the analyst attempts to perform colorimetric analysis, it is important to understand the theoretical aspects of the technique. The relationship between concentration and the light absorbed is the basis of theoretical consideration: Concentration and Light Absorbance The seemingly obvious way …
