liquid chromatography system high-performance thin layer chromatography system A system for on-line High-Performance Thin Layer Chromatography (HPTLC), an advanced and refined version of traditional Thin Layer Chromatography (TLC), designed to offer significantly improved performance in terms of resolution, sensitivity, and reproducibility. It utilizes finer and more uniformly sized stationary phase particles, leading to more efficient separations and more accurate quantitative analysis. MS MS:1003597
