General description
25 Glass plates 20 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
- Pressurized planar electrochromatography of DNS amino acids derivatives in silica gel and silanized silica gel systems with formic acid addition to the water mobile phase: This study explores the separation selectivity of dansyl (DNS) derivatives of amino acids using pressurized planar electrochromatography (PPEC) on Silica gel 60 TLC plates. The research demonstrates significant differences in separation selectivity between high-performance thin-layer chromatography (HPTLC) and PPEC systems, highlighting the electrophoretic effects in the PPEC system (Chomicki and Dzido, 2021).
- Thin-layer chromatography of DNS amino acids derivatives in systems with silica gel and silanized silica gel plates: This article presents investigations into the separation selectivity of DNS derivatives of amino acids on Silica gel 60 TLC plates. The study shows the impact of varying concentrations of acetonitrile in the mobile phase on the separation efficiency, providing valuable insights for optimizing analytical techniques in biochemical research (Chomicki and Dzido, 2022).
- Determination of β-blocking receptor drugs in silica gel TLC systems with the mobile phase containing surfactant: This research examines the retention and separation of β-blocking drugs on Silica gel 60 TLC plates using mobile phases with surfactants. The study assesses the effect of surfactant concentration on zone shape properties and provides a quantitative analysis of selected solutes, emphasizing the method′s environmental friendliness due to low propanol use (Traczuk and Polak, 2022).
