• RP18 - Octadecyl Bonded Silica Gel Reversed Phase for HPTLC
• F - Fluorescent indicator UV254. (Can be added to any adsorbent.)

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.

PREPARATIVE PLATES

Preparative TLC plates have adsorbent layers thicker than the 250 micron layers normally used for analytical separations. Thus, preparative plates can be used for separation of larger quantities of materials.The loading capacity for a given degree of sample component resolution increases roughly as the square root of the increased adsorbent layer thickness.

In preparative TLC, materials to be separated are often applied as long streaks rather than spots. After development, specific compounds may be recovered by scraping the adsorbent layers from the plate in the region of interest and eluting the separated material from the adsorbent using a strong solvent.·Thicker layers for higher capacity·Full range of plate sizes·Prep-scored option for convenient zone location·Available with preadsorbent sample loading zone·Calcium sulfate binder-soft later for easy scraping.
