Description
Silica gel 60 G is a chromatographic adsorbent for thin-layer chromatography (TLC) formulated with gypsum as binder. Identified by CAS number 7631-86-9 and empirical formula SiO₂, it has a molar mass of 60,09 g/mol and a density of 2,2 to 2,3 g/cm³. The gypsum content supports adhesion of the silica layer to glass or other plate supports during coating and drying. The silica gel 60 pore structure gives dependable retention for many polar and moderately polar compounds when standard mobile phases are applied. Users typically prepare an aqueous or solvent slurry, coat plates to the required layer thickness and activate before spotting. Consistent material properties help laboratories obtain reproducible Rf values across batches. The product is registered under EG nr. 231-545-4 and forms part of the established Silica Gel 60 range for TLC applications.
This article is part of Sorbents, silica gel & ion exchangers, in SPE & sample preparation.

Questions about Silica gel 60 G, for TLC (with gypsum), 500 g, plastic
What is this article?
Silica gel 60 G, for TLC (with gypsum), 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.
Which category should I open next?
