ورق TLC سیلیکاژل 60 پشت آلومینیومی کد 116484 مرک آلمان
TLC plates, unmodified silica gel 60
This range of plates uses Merck silica gel 60 with a
unique polymeric binder that results in a uniform and hard surface that
will not easily crack or blister. The smooth and extremely dense plate
coating ensures narrow bands and maximum separation efficiency with the
lowest background noise.
- Layer thickness 200 µm, particle size of 10 - 12 µm
- Flexible aluminium plates that can easily be cut to match individual separation requirements
- Two inorganic fluorescent indicators for UV detection of colourless substances
- Samples which absorb shortwave UV at 254 nm are detected due to fluorescence quenching
TLC plates, concentrating zone
These plates are based on different adsorption
properties of two silica adsorbents: An inert large pore concentrating
adsorbent where the samples are applied and a selective layer for the
separation. Independent of the shape, size or position of the spots the
sample always concentrates within seconds as a narrow band at the
interface of the two adsorbents, where the separation begins.
- Quick and easy sample application
- Includes a purification and concentration step
- Better resolution due to sharp bands
TLC plates, modified silica gel 60
Modified silica layers (layer thickness 200 µm) are well
suited for most problem separations that cannot be adequately resolved
using unmodified silica.
- Results less dependent on atmospheric humidity
- Allows use of aqueous solvent systems
- RP-modified silica provides a ready correlation with HPLC
- No catalytic activity for unstable substances (oxidative degradation)
