TLC silica gel IB2-F

[PolytheneSam]

Are TLC plates typically given a rating of some kind?  If someone had something like Baker-flex silica gel IB2-F (1B2-F?) what does that refer to?  They're 2.5 x 7.5 cm.

the f means flurocent (they glow in uv). The usual TLC plate made of an .1-.25mm silicagel 60 layer with a flurocent additive.

OK.  Would something that is normally fluorescent show up on these plates in either short wave (hand held mineral light) or long wave (fluorescent black light), ie. something with a benzene ring or indole ring?

The organics will show up one way or another. Often the aromatic group will absorb the UV giving a dark spot but if the organics fluoresce themselves then it will likely be a different color from the green fluorescence of the TLC plate so they will still show up. Another quick way to visualize the organics on a TLC plate is to expose the plate to iodine vapour, the organic will absorb the iodine vapour causing a visible dark spot.
