Notes:
Co-solvent effects are applied to allow use of concurrent solvent evaporation for applications requiring analysis of compounds eluted less than some 50° above the column temperature during sample introduction, i.e. at oven temperatures below some 100-120°C. Required conditions such as GC even temperature, concentration of the co-solvent and length of the uncoated pre-column (retention gap) are studied theoretically as well as experimentally for the case of n-heptane as co-solvent in n-pentane.
