Benefits

Superior flexibility

Depending on your application, you may use any detection method with your Metrohm IC system. Each detection method has its particular benefits regarding selectivity and sensitivity.

Overview of the detectors for Metrohm IC
Detector option	Benefits	Typical applications
Conductivity detector	Benefits: Universal detector for wide application field Maintenance free Non-destructive detection	Applications: Anions, cations, amines (Metrohm Suppressor Module available for more sensitive analysis)
UV/VIS detector	Benefits: Straightforward quantification of UV- and VIS-active substances across the entire UV/VIS range Maximum performance by flexible settings (wavelength, lamps, measuring channels) Upgradeable by iReactor for pre- and postcolumn derivatization Highly specific and sensitive, making even low-level detection possible	Applications: Direct UV/VIS detection: nitrogen and sulfur compounds, halogens, organic substances With post-column derivatization: transition metals, oxyanions as bromate and chromate in very low concentrations, amino acids, ammonium, etc. With pre-column derivatization: complexing agents as EDTA, NTA, PBTC
Amperometric detector	Benefits: Determination of electroactive, i.e., oxidizable or reducible, compounds. High selectivity and sensitivity for determination of concentrations down to the ng/L range.	Applications: Carbohydrates Sugar alcohols of all kinds Many anions (e.g., cyanide, sulfide, iodide, bromide) Many anions (e.g., cyanide, sulfide, iodide, bromide) Many cations (e.g., amines, aromatic amino acids) Organic substances (e.g., phenols, catecholamines, vitamins)
Hyphenated mass detectors	Benefits: High sensitivity and specificity Simultaneous analysis possible Peak verification and identification	Applications: Speciation of (trace) metals and metaloids (As, Hg, Se; IC-ICP/MS) Quantification and profiling for carbohydrates (IC-MS, IC-MS/MS) Organic molecules, e.g., amines (IC-MS, IC-MS/MS) Pesticides, e.g., glyphosate, AMPA (IC-MS, IC-MS/MS) Halogens and halogenated compounds, e.g., perchlorate, bromate, haloacetic acids (IC-MS, IC-MS/MS)
