Answer:An RP-18 (C18) modified silica gel 60 layer provides reversed-phase chromatographic retention.
Answer:The glass-backed plates are 20 × 20 cm, with an approximately 250 µm silica layer.
Answer:The package contains 25 plates. The F254s fluorescence indicator supports UV visualization under suitable conditions.
Merck Silica Gel 60 RP-18 F254s TLC plates use a reversed-phase octadecyl-modified silica layer to separate compounds through interactions with a hydrophobic stationary phase and a suitable mobile phase. Each glass-backed plate measures 20 × 20 cm, with a coating thickness of approximately 250 µm and a fluorescent F254s indicator for visualization under appropriate UV illumination. The silica gel matrix has a typical pore diameter of 60 Å and particle size around 10–12 µm. Reversed-phase TLC can be useful for screening solvent systems, comparing related compounds and supporting development of complementary reversed-phase liquid chromatography methods. The plates are supplied in a package of 25, providing a consistent stationary phase for parallel qualitative comparisons. Mobile-phase composition, application volume, chamber saturation and visualization conditions should be kept consistent when comparing chromatographic behavior. These are ready-coated analytical TLC plates, not loose silica, preparative columns or finished HPLC columns.
