We report the use of silver-thiolate chromatographic material (AgTCM) as a stable material for use in TLC. The AgTCM stationary phase operates under the same principles as silver-ion chromatography, separating compounds by degree of unsaturation; however, the AgTCM stationary phase shows considerable advantages over Ag-TLC in terms of light stability and shelf lifetime. We demonstrate the light stability of the AgTCM-TLC and its application for separations based on the degrees of unsaturation using fatty acid methyl esters (FAMEs) and polycyclic aromatic hydrocarbons (PAHs).
我们报告了使用银-硫醇色谱材料（AgTCM）作为 TLC 中使用的稳定材料。AgTCM 固定相的工作原理与银离子色谱相同，通过不饱和程度分离化合物；然而，与 Ag-TLC 相比，AgTCM 固定相在光稳定性和货架寿命方面具有相当大的优势。我们展示了 AgTCM-TLC 的光稳定性及其在基于脂肪酸甲酯（FAMEs）和多环芳烃（PAHs）的不饱和程度分离中的应用。
