Description
Aluminium oxide 90 acidic is a column-chromatography sorbent based on aluminium oxide with empirical formula Al₂O₃, CAS number 1344-28-1, and EG nr. 215-691-6. Key physical parameters include a molar mass of 101,94 g/mol, density of 3,97 g/cm³, and boiling point of 2980 °C. The acidic activity grade provides a surface suited to separations and sample clean-up steps that require acidic alumina rather than basic or neutral grades. It is This material from manufacturer Carl ROTH is intended for use among sorbents for chromatography where aluminium oxide 90 acidic is specified in the method. Typical applications include adsorption chromatography of organic compounds under controlled polarity and pH-related retention. Select the acidic grade when protocols demand acidic alumina 90, and apply standard laboratory handling for fine inorganic powders during weighing and column packing.

Questions about Aluminium oxide 90 acidic, for column chromatography, 500 g, plastic
What is this article?
Aluminium oxide 90 acidic, for column chromatography, 500 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Sorbents, silica gel & ion exchangers, inside SPE & sample preparation, in Chromatography equipment.
Loose sorbent, silica gel and ion-exchange resin are the phases bought in bulk to pack a column or to stir into a solution. Particle size and activity, or the ion-exchange capacity, are the specification. A TLC silica and a flash silica of different particle sizes are not the same separation.
Solid-phase extraction holds a compound on a sorbent while the rest of the sample is washed away, then releases it in a small volume. The sorbent, the bed mass and the solvents are the method. Silica, ion exchangers and polymer phases do different jobs. A flash column is the same idea scaled toward purification rather than trace cleanup. The molecules are on PubChem, named by IUPAC.
