| Abstract | A high‐speed reverse‐phase liquid chromatography column packed with 3 μm particles has been used to separate different epoxy resin formulations used in manufacturing fiber‐reinforced composites. The mass transfer of the solute between the stationary phase and the mobile phase is improved with the decrease of the particle diameter, and the height equivalent to a theoretical plate remains low even at higher flow rates of eluent. The separation of a typical epoxy resin was achieved with good resolution in less than 6 min on a short column 4 cm long packed with 3 μm particles, as compared to about 30 min on a 30 cm long column packed with 5 μm particles. Moreover, the regeneration time with gradient elution is considerably reduced with a short column. Separations of different formulations are shown and the advantages and disadvantages of these 3 μm packings for a quality control laboratory are discussed. In addition, the ageing of Narmco Rigidite 5208/WC3000 prepreg at room temperature in a controlled atmosphere has been quantified using these high‐speed columns. |
