Abstract
High-performance thin-layer chromatography (HPTLC) is a separation technique commonly used to identify and quantify compounds in chemical mixtures. Preliminary experiments indicated that Lichrospher silica gel 60 F254s HPTLC sheets were the most suitable for analyzing vitamin B12 compounds. This study revealed the advantages of miniaturized Lichrospher HPTLC for analyzing authentic vitamin B12 compounds as short migration distances (5 cm) and short development times (<45 min) in combination with high separation efficiency and sensitivity (>25 pmol at 254 nm). The practicability of using miniaturized HPTLC was demonstrated by the separation and identification of vitamin B12 compounds purified from foods using an immunoaffinity column.
