Metrosep A Supp 5 250mm x 4.0mm

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. Carrier material Polyvinyl alcohol with quarternary ammonium groups Column capacity 85 µmol (Cl–) Column dimensions 250 x 4.0 mm Eluents Carbonate eluent (standard eluent) Sodium hydrogen carbonate: 1.0 mmol/L; 168 mg/2 L Sodium carbonate: 3.2 mmol/L; 678 mg/2 L Housing material PEEK Max. pressure 15 MPa Maximum flow 0.8 mL/min Organic modifier 0 - 100% (particularly acetone, acetonitrile, methanol) Particle size 5 µm pH range 3–12 Standard flow 0.7 mL/min Temperature range 20–60 °C
