Quantity/Pack Size – 500 g
Form – Fine powder
Grade – LR (Laboratory Reagent)
Application – Thin-layer chromatography (TLC)
Product Overview
Silica Gel G (for TLC) LR is a high-performance adsorbent designed specifically for thin-layer chromatography applications. This fine, white powder contains calcium sulfate as a binder, ensuring uniform layer formation and enhanced separation efficiency. The LR (Laboratory Reagent) grade guarantees consistent quality, making it ideal for reliable chromatographic analysis. Its controlled particle size distribution and high surface area provide excellent resolution of complex mixtures, while the gypsum binder improves mechanical stability of the TLC plates. This product is chemically inert, ensuring minimal interference with sample components during separation. The silica gel’s high adsorption capacity allows for effective separation of both polar and non-polar compounds. Its uniform particle size distribution contributes to reproducible Rf values across multiple runs. The material is carefully processed to remove impurities that could affect chromatographic performance. This silica gel variant is particularly suitable for preparative TLC applications where higher sample loads are required. The product comes in a moisture-resistant packaging to maintain its adsorption properties during storage.
FAQs
1. What is the difference between Silica Gel G and regular silica gel for TLC?
Silica Gel G contains calcium sulfate (gypsum) as a binder, which improves the mechanical stability of TLC plates compared to regular silica gel that lacks this binder.
2. Can this silica gel be used for column chromatography?
While primarily designed for TLC, this product can be used for flash chromatography with appropriate modifications, though specialized column chromatography silica gels may offer better performance.
3. What is the typical particle size range for this silica gel?
The particle size typically ranges between 5-40 microns, with an average of about 10-15 microns, which is optimal for TLC applications.
4. How should this silica gel be stored to maintain its properties?
Store in a tightly sealed container at room temperature, away from moisture and direct sunlight to prevent degradation of its adsorption properties.
5. Is this silica gel suitable for separating amino acids?
Yes, this LR grade silica gel is appropriate for separating amino acids and other polar compounds in TLC applications when used with suitable mobile phases.
