• NH2 - Aminopropyl Bonded Silica Gel
• F - Fluorescent indicator UV254. (Can be added to any adsorbent.)
• Fluorescent indicator has green fluorescence at 254 nm
• HPTLC - High Performance Thin Layer Chromatography

Normal Phase - Unibond™ Amino (NH2) & Cyano (CN) HPTLC UNIPLATES™

• High efficiency 8 micron (ave) adsorbent with narrow particle and pore size distribution
• 150 micron adsorbent layer thickness for fast separations
• Homogeneous layer allows linear or radial separations
• Smooth adsorbent surface for noise free densitometry

High Performance UNIPLATES provide high resolution separations in less than five minutes with migration distances as little as 5 to 7 cm. These plates are prepared with high efficiency silica gel having an 8 micron average particle diameter and narrow particle size distribution. The adsorbent layers are only 150 microns thick, resulting in more rapid solvent migration. 

The adsorbent capacity is more than adequate for small samples used in high performance TLC techniques. Typically, sample volumes for high performance TLC are less than one microliter. Sample spots are normally smaller than one millimeter in diameter.

Samples are spotted 1.0 to 1.5 cm from the bottom edge of the plate and 0.3 to 0.5 cm apart. Since smaller samples are applied, one 10 x 10 cm plate can separate as many samples as can be separated on a 20 x 20 cm plate using standard TLC techniques. The smooth homogeneous surface of HPTLC UNIPLATES gives high signal-to-noise ratios for densitometric scanning, thus increasing sensitivity and precision.
