LC2800G is a model certified by the Ministry of Industry and Information Technology and is specifically designed for ROHS 2.0 testing of benzenes. This product can achieve the separation and detection of 80% organic compounds. High Performance Liquid Chromatography (HPLC) is a widely used analytical method for separating and identifying organic compounds. It is an important branch of chromatography and utilizes liquid as the mobile phase. By pumping a single solvent or a mixture of solvents, buffers, and other mobile phases of different polarities or proportions into a chromatographic column filled with a fixed phase, each component in the column can be separated and detected by the detector, thereby achieving the analysis of the sample. This method has become an important separation and analytical technique applied in the fields of chemistry, medicine, industry, agriculture, commercial inspection, and forensic science.
