Description

Silica gel is a type of stationary phase material used in column chromatography, a separation technique that separates components of a mixture based on their chemical properties. The silica gel 60 offered by Merck has a particle size of 0.040-0.063 mm, which is equivalent to 230-400 mesh according to the ASTM standard. This makes it suitable for use in column chromatography applications where a fine, uniform particle size is required for efficient separation of target compounds. Merck’s Silica Gel 60 is a high-quality product that is widely used in research and industrial laboratories for various chromatography applications.

Synonyms: Gallotannin, Tannin

General description

Tannic acid (TA) is a natural, non-toxic organic acid with corrosion inhibitive property for metals and alloys. A chemiluminescence (CL) system of KIO₄ (potassium periodate)–H₂O₂ (hydrogen peroxide)–Tween40 has been employed in the detection of tannic acid in industrial wastewater. Tannic acid hydrolyzes to form mainly glucose and gallic acid. Its astringent property is due to the presence of polyphenolic groups.

Application

Tannic acid may be used in the following processes:
• Synthesis of ferric tannate complexes by reacting with metallic iron.
• As a protein deproteinizing agent in genomic and plasmid DNAs preparation.
• As a reductant in the synthesis of metal nanoparticles.

With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in “gradient grade” as well as “isocratic grade”. This enables to minimize the gradient effect of the solvent involved. Filtered by 0.2 µm filter

Description

For thin-layer chromatography applications, we offer Aluminum TLC plates that are coated with silica gel containing a fluorescent indicator F254. These silica gel TLC plates are available in a set of 50 and measure 5×10 cm. Our classical silica TLC plates are created by combining our established silica gel 60 with a unique polymeric binder. This combination produces a very adherent and robust surface that will not crack or blister and can even withstand writing with a pencil without risking damage to the layer.
