Robust but Highly Selective and Performant - the IC Anion Column Metrosep A Supp 10
14 December 2005
With the Metrosep A Supp 10, Metrohm presents a favorably-priced anion column that is not only suitable for the determination of the standard anions, but also for complex applications. The straightforward separation of sulfite and sulfate is just one example of the wide range of uses of this new IC column. An additional advantage of the Metrosep A Supp 10 is the position and small size of the system peak (carbonate), which appears clearly before the chloride peak and therefore does not interfere with the determination.
The Metrosep A Supp 10 is based on a high-capacity styrene / divinylbenzene copolymer with a particle size of only 4.6µm. Metrohm has developed and optimized this well-proven column design even further. The result is an extremely robust anion column with excellent separation performance and adjustable selectivity. The separation properties of the Metrosep A Supp 10 can be varied within a wide range. This allows the new IC anion column to be adjusted to a vast number of applications, thus replacing some of the special columns that were previously required.
The Metrosep A Supp 10 is extremely flexible regarding alterations in selectivity. It is, for example, possible to shift the bromide and nitrate peaks widely within the chromatogram by just varying the column temperature. The retention times of these anions become shorter as the temperature increases.
The new Metrosep anion column is available in four different lengths ranging from 50mm to 250mm.
