The effects of viscosity of the studied samples and of carbon fibres as an added crystallisation aid were also investigated. Equilibrium temperatures for the solid–liquid phase transition are in accordance with literature for materials that were often checked, such as acetonitrile, showing the quality...
Two solvents were used: solvent A consisted of a mixture of acetonitrile/water/ methanol/hexane/tris buffer at ratios of 80:7:3:1:1, whereas solvent B was a mix of methanol and hexane at a ratio of 5:1. The HPLC was run at a flow rate of 1 ml min À 1, with an injection ...
