Although the separation power of HPLC is
considerably less compared to GC, there are
some advantages. There is no need for
lyophilizing the sample material, so there
is no loss of time needed for drying.
Furthermore, as the HPLC methods analyze
the dehydrated free fatty acids, no further
derivatization is needed, thus reducing the
total analysis time even more. The HPLC
method is useful in the analysis of Poly-
(3HB-co-3HV ) types of PHA.
