The Metrosep Anion Dual 3 - 100/4.0 made of PEEK is particularly suitable for biological samples. Its performance profile is identical to that of the Metrosep Anion Dual 2 - 75/4.6. This means that ions which elute early are separated very well and that oxyhalides can be determined very efficiently. The Metrosep Anion Dual 3 - 100/4.0 can also be used for samples with high chloride but low nitrite contents.
When working with amperometric detection, the Metrosep Anion Dual 3 - 100/4.0 can be used for the determination of bromide and iodide.
