It is possible to detect all ion chromatography related items such as conventional anions, cations, cyanide ions, iodide ions, sugars, small molecule organic acids, hexavalent chromium (chromate mist), transition metals, etc. by configuring conductivity detectors, amperometric detectors, and ultraviolet detectors. The plug-in design of ampere and conductivity detectors allows for their free switching. One machine with multiple capabilities, capable of meeting customers' routine testing requirements while upgrading post column derivatization, online enrichment, online matrix elimination, and other functions. Its perfect and outstanding performance takes chromatographic analysis to a new and higher level. A highly flexible system that can address potential challenges and advanced application scenarios, improves work efficiency, expands work capabilities, and enhances chromatographic performance.
