Silica Gel G & GF UNIPLATES are the most widely used silica gel TLC plates. No organic substances are added to these products, thus making them compatible with sulfuric acid charring visualization.
These plates are commonly scraped from the glass backing to isolate separated components for other analytical procedures. They are compatible with all organic solvents, however, they are not recommended for use in systems containing greater than 20% water because of the solubility of the gypsum binder in aqueous solutions. (For water tolerance see the GHL & GHLF series of plates.)
The "G" stands for Gypsum and indicates that calcium sulfate hemihydrate (CaSO4·1/2H2O), a refined form of gypsum, has been included in the adsorption formulation. Gypsum functions as a binder, improving the cohesion of the adsorbent particles and increasing the adhesion of the layer to the glass substrate.The "F" indicates the presence of a short wave UV indicator that is fluorescent at 254 nm.
GENERAL CHARACTERISTICS:
- High performance silica gel provides faster separations, higher resolution, and improved sensitivity
- Accepts all typical chromatography solvents (20% water max)
- Compatible with essentially all visualization reagents including sulfuric acid charring
- Spraying reagent is suggested; layer is incompatible with aqueous dipping technique (use GHL or HL for dipping)
