Product Overview

Silica Gel H For Thin Layer Chromatography (CAS No. 112926-00-8) is a polar amorphous silica adsorbent intended for planar chromatographic separations without the conventional gypsum-type binder associated with G-grade TLC silica. The exposed silica surface provides silanol-mediated adsorption and normal-phase selectivity, while the binder-free character allows laboratories to control plate preparation or use the material in procedures specifically requiring H-type silica.

The Thin Layer Chromatography product form is intended for preparation of TLC layers where a binder-free silica system is preferred. It can be used for qualitative separation, reaction monitoring, purity studies and development of chromatographic solvent systems.

Typical Applications

• Preparation of binder-free silica TLC layers.
• Qualitative separation of organic and inorganic sample components compatible with normal-phase TLC.
• Reaction monitoring during preparative synthesis.
• Purity and identity comparison of laboratory samples.
• Solvent-system screening before column chromatography.
• Specialised TLC procedures requiring H-type silica.

Common Synonyms

• Silica gel H
• TLC silica gel H
• Thin-layer chromatography silica gel H
• Chromatographic silica gel H
• Amorphous silica gel without binder

Storage Conditions

Store tightly closed and dry to maintain predictable surface activity and coating behaviour. Protect from organic vapours, dust and chemical contamination that could occupy adsorption sites or create background zones during TLC development.
