Macherey-Nagel™ Alugram™ RP-18 W/UV254 Modified Silica Phase
Description
For use in normal or reverse phase HPTLC. Macherey-Nagel™ Alugram™ RP-18 W/UV254 Modified Silica Phase are aluminum sheets coated with wettable layers of modified nano silica that can be developed with purely organic and organic/aqueous solvents and purely aqueous eluents.
Alugram™ aluminum sheets are easy to handle, lightweight and flexible. The sheets have high chemical resistance and are suitable for most solvents. They are unbreakable but easy to cut with scissors, with no flaking of the silica.
- Nano silica 60 with partial octadecyl modification, wettable with water
- Normal phase or reversed phase separation modes
- Can be used with eluents from anhydrous solvents to aqueous mixtures
- Indicator: acid-resistant product with a pale blue fluorescence for short-wave UV (254nm)
- UV-absorbing substances appear as dark-blue to black spots on a light-blue background
- Order of polarity: silica > DIOL > NH2 > CN > RP-2 > C18-50 > RP-18 W > C18-100
- Carbon content 7.5%
- pH stability: 2-10
