Metrosep Dual 4 - 100/4.6

Metrosep Dual 4 - 100/4.6
Order number: 6.1016.030

The Metrosep Dual 4 separation columns are based on a functionalized Monolith based on silica gel. The Monolith permits an eluent flow of up to 5 mL/min. Despite the high flow, the column is characterized by low backpressure. In contrast to traditional materials, the Monolith has a much larger surface due to its structure of macropores and mesopores. This contributes to the high column capacity with simultaneously very low dead volume.

The Metrosep Dual 4 - 100/4.6 is suitable for a great number of applications. All standard anions can thus be separated in less than nine minutes. The high column capacity makes it largely insensitive to matrix influences. Even in a matrix of 3 g/L chloride, carbonate and sulfate, 0.5 µg/L perchlorate can be detected. The column is therefore used in perchlorate analysis in accordance with EPA standard 314.

    Even though the Dual 4 columns are based on a very stable monolithic silica material, the use of the Dual 4 Guard column is recommended to increase the security of the analytical column even further. The Dual 4 precolumn consists of a PEEK cartridge  which is also filled with monolithic silica gel. The cartridge is easy to exchange and is contained in an aluminum holder which is connected directly to the analytical column. This proven «On-Column Guard System is easy to use and additionally minimizes the dead volume.
