• F - Fluorescent indicator UV254. (Can be added to any adsorbent.)

Diol modified silica gel layers offer a moderately polar stationary phase, less polar than native silica gel.  They offer different selectivity than silica in a normal phase environment and can be used in reversed phase separations due to the organic function group surface modification.  Surface modification also reduces the sensitivity to water in normal phase chromatography offering better reproducibility.

Based on a 60 Angstrom silica gel the carbon content is approximately 5%.  Abrasion resistant binder results in a hard surface that is compatible with both 100% water as well as organic solvents.  Layers include an acid resistant pale blue UV254 fluorescent indicator.  

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.
