Background

The infrared spectrum can analyze pure substances with single components and mixture with multiple components, and ATR (Attenuated Total reflection) is an accessory for infrared spectrum detection, is widely applied to various solid and liquid sample tests, and has the principle that infrared light emitted from a light source passes through the surface of a sample with small refractive index, and when the incident angle is larger than the critical angle, the incident light can generate Total reflection. In fact, the infrared light is not totally reflected, but penetrates into the surface of the sample to a certain depth and then returns to the surface. In the process, the sample has selective absorption in the incident light frequency region, the intensity of reflected light is weakened, and a map similar to the transmission absorption is generated, so that the structural information of the chemical components on the surface layer of the sample is obtained. However, the ATR accessory greatly simplifies the pretreatment process of the sample, but other tools are needed for collecting and detecting liquid and powdery solid, and the absorption peak of carbon dioxide in the spectrum detected by the ATR accessory often interferes with the analysis of the spectrum, which affects the accuracy of the test result.
