EMD* NH₂-Modified Silica Gel 60 Aluminum 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.

The amino modified NH₂ plate provides weak basic ion exchange characteristics with special selectivity for charged compounds. Since most substances separated on modified plates are colorless, these plates contain the blue fluorescent, acid-stable UV indicator F_254s. Samples which absorb shortwave UV at 254 nm are detected due to fluorescence quenching.

• 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)
