Portable Colorimeter User ManualQ1: How does a colorimeter work?
A1: Colorimeters rely on the concept of the Beer-Lambert law, which assumes that the absorbance of a substance is proportional to its concentration. For example, the higher the concentration of a solution, the higher the absorbance reading. Many chemical and biological experiments are based on this concept. To obtain a Beer's law curve, several standards (solutions of known concentration) are prepared and their absorbance values are determined using a colorimeter.
Q2: What is colorimetry?
A2: A colorimeter is a device that measures light absorbance (how much light is absorbed) and light transmission (how much light passes through) in a liquid by analyzing the intensity of the color.
Q3: What are the limitations of a colorimeter?
A3: One limitation of chemical colorimeters is that differences in certain substances may lead to inaccurate test results. According to Global Water Instrumentation, because these differences are different for each substance, a chemical colorimeter alone is not a completely foolproof testing device.
Tips: Portable colorimeter in the paper industry
A portable colorimeter has become an indispensable instrument for optical analysis in scientific research and life activities. For example, in the production of paper, chromaticity is particularly important for the control of paper color. Because of the wide range of materials involved in the materials used to make paper, and the bleaching and pulping processes in paper production require chemical and mechanical processing, the paper industry is particularly stringent in monitoring the product. In addition, the papermaking process is a 24-hour continuous production, and the production site environment is extremely poor, with high humidity and vibration, which is very unfavorable to the use of chromatography. Therefore, the use of LED as a light source is very popular. The light source of this instrument can be stable for a long time.
