High performance liquid chromatography (isocratic)Introduction:
LC-20 isocratic high-performance liquid chromatography is a new type of liquid chromatography instrument developed by Shanghai Jinghe Analytical Instrument Co., Ltd. to quickly meet diverse customer needs. It is optimized based on the original LC-100 liquid chromatography instrument, developed, designed, and manufactured domestically. The LC-20 isocratic high-performance liquid chromatograph realizes human-machine dialogue, which can monitor the operation status of the instrument in real time, make judgments on potential and existing faults, and provide online solutions. The instrument also fully realizes remote quasi unmanned operation, greatly improving the efficiency of instrument use. At the same time, through the high-precision AS-100 automatic sampling system, automatic sampling is achieved to suppress cross contamination of samples and provide sample analysis accuracy. LC-20 isocratic high-performance liquid chromatography can be widely used in various analytical fields such as research and development, pharmaceutical inspection, food testing, chemical analysis, environmental monitoring, etc.
