• HPTLC - High Performance Thin Layer Chromatography
• RP18 - Octadecyl Bonded Silica Gel Reversed Phase for HPTLC
• F Fluorescent indicator UV254. (Can be added to any adsorbent.)
• Fluorescent indicator has green fluorescence at 254 nm

These reversed phase TLC plates have been manufacturer to be only 50% silanized.

TLC layers that are 100% silanized are extremely hydrophobic so this layer offers a happy medium for those applications involving slightly or highly aqueous mobile phases.

Reversed Phase Unibond™ Series HPTLC UNIPLATES™

The availability of both normal phase and Reversed Phase HPTLC UNIPLATES™ completes HPTLC as a
sensible, efficient and cost effective alternative technique for quantitative analysis. These Reversed Phase adsorbents share the features and benefits of silica gel

HPTLC plates: high efficiency adsorbents, 150 μm layer thickness, and smooth surface for densitometry. In the High Performance format, Analtech offers several varieties of supports. A hydrocarbon impregnated layer, similar to the analytical RPS UNIPLATE, offers complete aqueous solvent compatibility Three nonpolar bonded supports in the UNIBOND™ series are available: RP2, RP8, and RP18.

These fully silanized silica gels share complete compatibility with all organic solvents. However, due to the extreme hydrophobic nature of the RP18 adsorbent, aqueous wettability is limited to approximately 60% water in the mobile phase. Wettability is correspondingly higher with the slightly more polar shorter chain RP series plates.
