Outstanding separation properties and high-capacity – these are the things which clearly distinguish the Metrosep A Supp 19 product family from the rest of the column portfolio. It features best peak symmetries and selectivities as well as high thermal, mechanical and chemical stability, which makes it extremely robust and stable in the presence of higher flow rates and pressures.The shortest anion separation column of the Metrosep A Supp 19 product family is the 100 mm version – outstandingly suitable for simple applications that require rapid and robust analytics. With elevated flow, reliable determination of the standard anions is possible in less than 7 minutes. Even at these higher flow rates, the separation between fluoride and the injection peak is guaranteed. Short elution times permit a high sample throughput, which is particularly important for contract laboratories and in routine analysis. A further application area of the Metrosep A Supp 19 - 100/4.0 is the determination of analytes which usually have very late elution, e.g. perchlorate or citrate. Due to high flow rates and strong eluents, even analytes such as these can be determined in a very short time, thus rendering the entire analysis time-saving and efficient.

Outstanding separation properties and high-capacity – these are the things which clearly distinguish the Metrosep A Supp 19 product family from the rest of the column portfolio. It features best peak symmetries and selectivities as well as high thermal, mechanical and chemical stability, which makes it extremely robust and stable in the presence of higher flow rates and pressures.With the longest of the columns, i.e. the 250 mm version, the portfolio of the Metrosep A Supp 19 product family is rounded out to include a high-performance separation column. The exceptionally stable packaging ensures that the separation column will enjoy a long service life. With its unsurpassed separating efficiency, it is suitable for even the most complex application challenges. This means that the possible usages of this anion separation column greatly exceed the standard applications.Thanks to the extremely high capacity of this separation column, combined with its outstanding plate counts, even the most demanding sample matrices are easily mastered with the Metrosep A Supp 19 - 250/4.0.The separation column can also be readily used for gradient applications to further optimize the separation, as for example for the determination of organic acids of low molecular weight.

The 150 mm version of the Metrosep A Supp 5 is distinguished by its very good separation properties. High plate numbers and excellent peak symmetries facilitate working in the lower µg/L range. The particle size of 5 µm makes a decisive contribution to the separating efficiency of this column. The Metrosep A Supp 5 - 150/4.0 offers the optimum combination of selectivity and capacity, with which even complex separation tasks can be solved within a short time. This property makes the Metrosep A Supp 5 - 150/4.0 one of the best universally applicable standard IC columns.

The Metrosep A Supp 19 Guard/4.0 reliably protects the anion separation columns of the Metrosep A Supp 19 product family against contaminations from the sample or eluent and thus prolong their service life significantly. The guard columns and separation columns of the Metrosep A Supp 19 product family are made of PEEK and filled with the same material. This ensures that the chromatographic separating efficiency is not restricted in any way. The "On Column Guard System" makes it possible to screw the guard column onto the anion separation column directly and conveniently. The economical price and simple handling make the Metrosep A Supp 19 Guard/4.0 the ideal protection for the separation column.

The Metrosep A Supp 5 - 50/4.0 separates the seven standard anions in less than 6 minutes. Even fluoride is still separated from the injection peak and can be integrated perfectly. Like all columns in the A Supp 5 product range, the column based on a polyvinyl alcohol polymer is characterized by high plate numbers and therefore by outstanding separating efficiency. The Metrosep A Supp 5 - 50/4.0 is the column of choice when simple separation tasks need to be solved in a short time – and that without having to sacrifice very low limits of detection.

6.1006.510

The Metrosep A Supp 5 - 100/4.0 allows highly efficient, rapid separations. This property makes the Metrosep A Supp 5 - 100/4.0 the standard column for short analysis times and the determination of anions which elute late (e.g., perchlorate).

6.1006.530

The high-performance separation column from Metrohm with an extremely high number of plates for the most demanding separation tasks. Even complex separation problems can be solved easily and reproducibly with the Metrosep A Supp 5 - 250/4.0. The high capacity of the column allows, for example, the detection of 1 µg/L bromate along with 150 mg/L chloride without sample preparation. The range of applications possible with this column far exceeds the detection of standard anions. The Metrosep A Supp 5 - 250/4.0 is the column of choice when it comes to reliable monitoring of the high purity standards in the semiconductor industry or of the boiler feed water of power plants.
