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.

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.

6.1006.620

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.

Disinfection byproducts from water treatment are suspected not only of being health hazards but even of being carcinogenic. Oxyhalides have therefore become the subject of many investigations and standards (e.g., EPA 300.1 Part B, EPA 317.0, EPA 326.0). Of primary concern is bromate, which forms from bromide during the ozonization of drinking water. The Metrosep A Supp 7 - 250/4.0 is a high-performance separation column for the parallel determination of standard anions, oxohalides and dichloroacetic acid. With this column, 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.

6.1006.640

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.

The Metrosep A Supp 4 - 250/4.0 is an extremely robust column with very good separation properties. The separation phase is comprised of polyvinyl alcohol particles with quaternary ammonium groups and a diameter of 9 µm. This structure guarantees great stability and a greater tolerance to very small particles that could pass through the integrated filter pad. The Metrosep A Supp 4 - 250/4.0 has a medium ion exchange capacity; sulfate elutes after 12.5 minutes. The plate numbers that can be achieved with this separation column is higher than those for the Metrosep Anion Dual 2 - 75/4.6. The A Supp 4 - 250/4.0 is particularly suitable for all routine tasks in water analysis.
