• CN - Cyanoethyl Bonded Silica Gel
• F - Fluorescent indicator UV254. (Can be added to any adsorbent.)
• 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.

Scored UNIPLATES™

Most UNIPLATES can be supplied with the glass backing scored at specific locations to permit convenient “snapping” into smaller plates. This Analtech feature provides increased versatility and can mean cost savings over plates already cut to smaller sizes.

Different adsorbents, mobile phases, and analytical conditions can be tested quickly and economically. A plate can be spotted, then snapped into several smaller plates for developing in different solvent mixtures to determine the best separation.

A plate can be spotted, developed, then snapped into several smaller plates, and then subjected to different visualization techniques.

Scored UNIPLATES are available in two standard formats:

1. 20 x 20 cm scored UNIPLATES have three score marks 5 cm apart. Each plate can be snapped to produce four 5 x 20 cm plates or any multiple of 5 cm width.
2. 10 x 20 cm scored UNIPLATES have seven score marks 2.5 cm apart. Each can be snapped to produce eight 2.5 x 10 cm plates or any multiple of 2.5 cm width.
