Si-60 glass TLC plates are essential laboratory tools used for thin-layer chromatography (TLC), featuring a high-quality stationary phase of silica gel 60 coated evenly onto a rigid, chemically resistant glass backing. The silica gel 60, with a pore size of 60 Ångströms, provides excellent adsorption properties, making these plates ideal for the separation and analysis of a wide range of organic and inorganic compounds.
The plates typically have a layer thickness of about 250 micrometers, which offers optimal resolution and reproducibility in chromatographic separations. Many Si-60 TLC plates are impregnated with a fluorescent indicator (F254), which enables sensitive detection of sample spots under UV light at 254 nm, greatly simplifying qualitative analysis.
The Si-60 glass TLC plates are widely utilized in thin-layer chromatography for the separation and analysis of complex mixtures. These plates are characterized by a uniform layer of silica gel 60 adhered to a glass backing, providing a stable and reliable medium for chromatographic applications.
Features of Si-60 glass TLC plates
-
Particle Size and Distribution: The silica gel 60 used in these plates typically has an average particle size ranging from 10 to 15 µm, with a distribution between 5 to 20 µm. This fine particle size contributes to improved separation efficiency and resolution.
-
Layer Thickness: The silica layer is commonly applied at a thickness of approximately 250 µm, ensuring consistent and reproducible results across analys
-
Binder System: A unique polymeric binder is employed to adhere the silica gel to the glass support, resulting in a hard, uniform surface that resists cracking or blistering. This robust construction allows for writing on the surface with a pencil without damaging the layer.
-
Fluorescent Indicator Options: Si-60 TLC plates are available with or without fluorescent indicators, such as F₂₅₄, facilitating the detection of colorless substances under UV light.
