Applications of Carbon Powder in Column Packing for High Performance Liquid Chromatography

Abstract

Performance of carbon packed columns for HPLC was tested. Carbons were prepared from PAN, nitrated and sulfonated coal tar pitches over the temperature range 600-900°C. D-glucose, sucrose and raffinose dissolved in distilled water were selected as moving phase.
The highest performance of separation was obtained with the carbons baked at 800°C.
