Ion chromatography should be fun and should not get on your nerves. Metrohm does everything it can to ensure that your IC system will work reliably with minimum service, maintenance and costs. Metrosep separating columns stand for good quality, a long working life and excellent results.
Some of our new columns for ion chromatography:
Metrosep Dual 4 - 25
Separation of some standard anions in less than a minute, e.g. nitrate in just 45 seconds - faster than many FIA systems.
Metrosep A Supp 7 - 250
Separation column for the simultaneous determination of the standard anions, the oxo halides and dichloroacetic acid.
Metrosep A Supp 10 - 50
Allows very fast separations of the standard anions. Ideal for straightforward separation tasks and non-critical matrices.

IC and RFIC Columns
Hydroxide-Selective Anion Columns
Hydroxide-selective, anion-exchange columns are optimized for use with a hydroxide eluent. Choose a hydroxide eluent column for use with an eluent generator for gradient work or trace analysis. Hydroxide eluents for isocratic or gradient elution are very convenient with Reagent-FreeTM Ion Chromatography (RFICTM) technology using electrolytic generation of the eluent. RFIC technology simplifies methods development for hydroxide-gradient systems since the electrolytic eluent generator provides gradient methods that are simpler to use than manually prepared isocratic eluents. Modern continuous-eluent-suppression systems are designed to suppress hydroxide eluents, even at very high eluting strengths.
Carbonate-Based Anion Columns
Each of these anion-exchange columns are optimized for use with a carbonate/bicarbonate eluent. Carbonate eluent columns are useful for well-characterized isocratic separations, including regulated methods for drinking and wastewater.
Specialty Anion Columns
Specialty columns are anion-exchange columns that can be used with nonsuppressible eluents such as nitric acid in combination with a variety of detection modes, including amperometric and UV-VIS detection.
Cation Columns
Cation-exchange columns are designed for high-resolution separations of inorganic cations, ammonium, amines, and transition metals. These columns provide an excellent approach to separations of alkylamines, alkanolamines, and quaternary ammonium ions.
Transition Metal Columns
Transition metal columns are designed for determination of transition and lanthanide metals in diverse sample matrices.
Ion Exclusion Columns
In ion-exclusion separations, Donnan exclusion causes strong acids to elute in the void volume of the column. Weak acids that are protonated in the acidic eluent are not subject to Donnan exclusion and penetrate into the pores of the packing. Separation is accomplished by differences in pKa, size, and hydrophobicity.
Trap Columns
Trap columns are short columns installed in the system to prevent unwanted analytes from interfering with the separation of your analytes of interest. IonPac trap columns contain high-capacity, low-efficiency, ion-exchange resin. The columns strip trace contaminants from the eluent and prevent them from reaching the guard and analytical columns. The trap is installed in the eluent line prior to the injection valve to prevent spurious peaks during gradient chromatography. These trap columns are specialized columns that remove unwanted analytes from the sample, and are installed before the analytical column.
Concentrator Columns
IonPac concentrator columns are designed primarily for high purity water analysis. The concentrator column strips ions from a measured volume of an aqueous sample matrix, concentrating the analyte species and lowering detection limits.

Smartline Column Oven 4050
Optimally suited for the majority of HPLC applications.
This column oven features heating and active Peltier cooling in the range from 10° below room temperature up to 140°C. Its contact oven design and equilibrating of the mobile phase before the column inlet ensure an even temperature distribution over the entire column for improved separation results. Active column eluate cooling minimizes peak broadening and noise/drift in subsequent detection.
