Metrohm AG products

Short, high-capacity cation column, which is used to purify the eluent flow. Even reagents of the highest quality level, e.g. "Ultrapur" or "puriss", can still contain minimum amounts of cation contamination. These are reliably held back by the Metrosep C Trap 1 - 30/4.0.

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 must be solved in a short time – and that without having to sacrifice very low limits of detection.

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).

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 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.

The Metrosep A Supp 5 - 150 in the Microbore version is distinguished for its excellent separation properties. The particle size of 5 µm makes a decisive contribution to the separating efficiency of this column. The Metrosep A Supp 5 - 150/2.0 offers the optimum combination of selectivity and capacity, with which even complex separation tasks can be solved within a short time. The 2 mm Metrosep A Supp 5 separation columns are packed with the same material as the corresponding 4 mm separation columns. The 150 mm version of this column type is used for universal applications at low eluent consumption. With its low eluent flow, this column is particularly suitable for IC-MS coupling.

The Metrosep A Supp 5 - 250/2.0 is the microbore high-performance separation column with which even complex separation problems can be solved easily and reproducibly. The range of applications possible with this column far exceeds the detection of standard anions. The Metrosep A Supp 5 - 250/2.0 is used wherever maximum separating efficiency must be combined with both the lowest of detection limits and low eluent consumption. With its low eluent flow, this column is particularly suitable for IC-MS coupling.

The Metrosep A Supp 7 - 150/4.0 is the shorter A Supp 7 column. It allows similarly complex separation tasks to be solved the same way as with the 250 mm version, with no significant loss in separating efficiency. Chlorite and bromate can thus be easily separated from standard anions with this separation column. With the Metrosep A Supp 7 - 150/4.0, these ions are determined with certainty and precision down to the lower µg/L range. The high detection sensitivity is achieved through the use of the 5 µm polyvinyl alcohol polymer, with which extremely high plate numbers and thus outstanding separation and detection properties are achieved. In addition, the separation can be adapted to the specific requirements of the application by modifying the temperature.

The Metrosep A Supp 7 - 150/2.0 is the shorter of the two A Supp 7 columns in the microbore version. With the Metrosep A Supp 7 - 150/2.0, these ions are determined with certainty and precision down to the lower µg/L range. The high detection sensitivity is achieved through the use of the 5 µm polyvinyl alcohol polymer, with which extremely high plate numbers and thus outstanding separation and detection properties are achieved. In addition, the separation can be adapted to the specific requirements of the application by modifying the temperature. This microbore column is particularly suitable for use with an MS detector.
