Comprehensive options for detection

Depending on the application, you may use any detection method with your Metrohm IC system.

This helps you to solve even the most challenging analytical tasks. You may even couple several detectors in series, if required by the application. Moreover, Metrohm ion chromatographs may also be interfaced with MS and ICP/MS detectors of virtually any brand.

Conductivity detection is the standard detection method in ion chromatography.

UV/VIS detection enables straightforward quantification for substances that absorb light in the ultraviolet or visible range.

Analytes typically determined by UV/VIS detection range from nitrogen and sulfur compounds to halogens, organic substances, and others.

Combined with post-column reactions, UV/VIS detection makes it possible to detect a number of ions, such as chromate, bromate, and transition metals, in very low concentrations.

Amperometric detection is an alternative to conductivity and UV/VIS detection.

It is mainly used to determine electroactive, i.e., oxidizable or reducible, compounds.

Typical applications of amperometric detection are sugars and sugar alcohols of all kinds as well as many anions (e.g., cyanide, sulfide, iodide, bromide), cations (e.g., amines, aromatic amino acids), and organic substances such as phenols, catecholamines, vitamins …
