Sep-Pak Alumina N 20 cc Vac Cartridge, 5 g Sorbent per Cartridge, 50 - 300 µm, 20/pk

Sep-Pak Alumina N An extremely active grade of alumina with neutral surface chemistry is found in vacuum cartridges. A very polar surface for analyte retention is provided by the aluminum oxide surface, which also possesses Lewis acid-like characteristics. While it functions in a manner comparable to silica, this normal-phase sorbent is somewhat more stable than silica, which has not been functionalized. For uses like fractionating synthetic crude oil, this neutral alumina is appropriate. For use with vacuum manifolds and automated SPE devices, these syringe-barrel-style cartridges are created.

Depending on how the sorbent's surface has been modified, alumina can be found in three different forms: Alumina A, Alumina B, and Alumina N. The pi-electrons of aromatic hydrocarbons interact specifically with alumina. Because of this, it is ideal for tasks like fractionating crude oil. Depending on your needs, acidic and basic grades can be used as low-capacity ion exchangers in aqueous mediums that are unaffected by high-energy radioactivity.

A male/male adaptor can be used to quickly and simply connect the Sep-Pak Alumina N Classic Cartridge to vacuum-assisted flow devices. It is designed to be used with a Luer-tip syringe that uses positive displacement. Certified Sep-Pak Alumina N cartridges are put through quality control to ensure repeatable separations. The cartridges provide greater performance for ultra-low-level analyte detection by reducing the chance of background interferences, which are frequently present in SPE devices.

Sep-Pak columns with "Neutral" sorbent and normal phase can be used with the Sep-Pak Alumina N Classic Cartridge. There are several uses for the Sep-Pak Alumina phase. Just a few applications include conducting analyses on synthetic organic compounds, pesticides, herbicides, priority pollutant isolation, and substitutes for conventional AOAC and EPA techniques. They can support volumes up to 1.8 mL with particle sizes of 50-300 µm, 120 pore size, and 1850 mg of sorbent per cartridge.
