EMD® RP-Modified Silica TLC Plates
When separation challenges cannot be adequately resolved with standard silica, you can count on our modified silica plates to facilitate your application. The system offers a free choice of solvents, so you can be sure that they meet your particular separation requirements. Modified silica TLC plates provide additional selectivities and significantly broaden TLC applications.
RP-2, RP-8 and RP-18 are based on silica gel 60 modified with aliphatic hydrocarbons. The chain length in combination with the degree of modification defines the ability to tolerate the water of the solvent system and strongly affects retention. Migration time increases in the order RP-2, RP-8, RP-18 using the same solvent composition.
Since most substances separated on modified plates are colorless, the majority of these silica plates contain the blue fluorescent, acid-stable UV indicator F254s (Cat. No. 1.05747.0001 is silanized and contains inorganic, green, F254 fluorescent indicators). Samples which absorb shortwave UV at 254 nm are detected due to fluorescence quenching. Cat. No. 1.05746.0001 is silanized and contains no fluorescent indicator.
• Results less dependent on atmospheric humidity
• Allows use of aqueous solvent systems
• RP-modified silica provides ready correlation with HPLC
• No catalytic activity for unstable substances (e.g. oxidative degradation)
Image(s) are representative of the product group and not necessarily the individual product.
