The problem working with this type of sample is that you have a lot of co-elutions. An alternative is calibrate the system with a n-Paraffins standard using a HP-1 column (a metal capillary column, because to bake the column from the C36+ you need a temperature higher than 400°C) using a SIMDIS system, but you will need to estimate the areas for each peak, because the baseline won't be flat in any part of the run.
Using a PONA column, probably a great part of your sample will remain in the column, even with the column bake and you will take a long time to finish the run.
For the light fraction, you will need to use the DHA technique, because the separation for light fraction (C10) is very poor in SIMDIS.
