Description

Description générale

1 Aluminium roll 500 x 20 cm

Our classical silica TLC plates are based on a combination of our proven silica gel 60 and the addition of a unique polymeric binder resulting in a very adherent and hard surface that will not crack or blister and even allow writing with a pensil on the surface without risk to damage the layer.

Application

• Determination of β-blocking receptor drugs in silica gel TLC systems with the mobile phase containing surfactant.: This paper investigates the use of silica gel TLC plates with surfactant-containing mobile phases for the separation and quantitative analysis of β-blocking receptor drugs. The environmentally friendly method provides accurate LOD and LOQ values for various drugs (Traczuk and Polak, 2022).


• Separation of peptides in thin-layer chromatography systems with C18 silica-based adsorbents.: This paper investigates the separation of peptides using thin-layer chromatography (TLC) systems with C18 silica-based adsorbents, including Silica gel 60 F₂₅₄ plates. The study demonstrates the utility of these systems in peptide analysis (Gwarda et al., 2016).
