High-performance thin-layer chromatography

Whether in monitoring the quality of pharmaceutical products or medicinal plants,  Merck's HPTLC plates for thin-layer chromatography (TLC) are faster and more reliable than conventional silica gel plates. Using them, complex matrices can be analyzed simultaneously and under identical conditions without preparation of samples.

Your benefits:

• Analysis up to five times faster
• Sensitivity increased up to ten-fold
• Improved reproducibility
• Cost effective

High performance silica gel plates: faster, more sensitive, more reliable

Merck's HPTLC plates for thin-layer chromatography are up to ten times more sensitive than conventional silica gel plates and deliver analysis results with high reproducibility up to five times more quickly. To do this, they use optimized silica gel sorbents which, with a particle size of 5 - 6 µm, are just half as large as usual. This guarantees a higher packing density and a smooth surface. The reduced diffusion creates sharp lines and marks. Together with the thin layer, this results in especially high-performance plates.

Different formats for specific customer requirements

Manual or automatic TLC applications: Thanks to their unbeaten separation performance, HPTLC plates are ideally suited to quantitative analyses, for example monitoring the quality of pharmaceutical products or medicinal plants. Merck supplies glass and aluminum plates in a wide range of formats for various customer requirements. The indicators used are green fluorescing F₂₅₄ and blue fluorescing F_254s (acid stable).
