一般描述

25块玻璃平板20 x 10厘米
RP修饰板用于两个目的:作为HPLC的试用方法和为特殊的分离选择各种溶剂系统。我们的RP修饰的硅胶层非常适合许多具有挑战性的分离,这些分离是未经修饰的硅胶所无能为力的。这些胶层使用水溶剂系统来分离极度非极性的物质,并对能适应离子对色谱的特定物质进行分析。更重要的是’,RP修饰的硅胶层很少受环境湿度的影响。和未修饰的硅胶不同,RP相不表现出催化活性。这使得它们成为易于氧化降解的不稳定物质的首选。

应用


  • Densitometric HPTLC method for qualitative, quantitative analysis and stability study of Coenzyme Q10 in pharmaceutical formulations utilizing normal and reversed-phase silica gel plates.: This study presents a high-performance thin-layer chromatography (HPTLC) method for analyzing Coenzyme Q10 in pharmaceutical formulations. The method employs both normal and reversed-phase silica gel plates to achieve qualitative and quantitative analysis, as well as stability testing of Coenzyme Q10 (Abdel-Kader et al., 2016).

  • Simultaneous Quantification of Gymnemic Acid as Gymnemagenin and Charantin as β-Sitosterol Using Validated HPTLC Densitometric Method.: This research develops a validated HPTLC densitometric method for the simultaneous quantification of gymnemic acid and charantin in herbal formulations. The method utilizes silica gel 60 F₂₅₄ plates for effective separation and quantification (Ahamad et al., 2015).

  • Estimation of catechin in Ayurvedic oil formulations containing Acacia catechu.: The study estimates the content of catechin in Ayurvedic oil formulations using HPTLC. Silica gel 60 F₂₅₄ plates are employed to ensure accurate quantification of catechin in these formulations (Dubey et al., 2009).

  • Development and validation of HPTLC method for estimation of tacrolimus in formulations.: This paper details the development and validation of an HPTLC method for estimating tacrolimus in pharmaceutical formulations. The method uses silica gel 60 F₂₅₄ plates for efficient separation and quantification of tacrolimus (Borhade et al., 2009).

  • Estimation of berberine in ayurvedic formulations containing Berberis aristata.: The research focuses on the estimation of berberine in Ayurvedic formulations. Using HPTLC with silica gel 60 F₂₅₄ plates, the study provides a reliable method for berberine quantification (Rout et al., 2008).
