The analytical methods discussed in this paper are: gas chromatography (GC), gas chromatography-mass spectrometry (GC/MS), high performance liquid chromatography (HPLC), solid phase extraction (SPE), and solid phase micro extraction (SPME). The user should be aware of the possibilities and limits of each method, bearing in mind the complexities of the pyrolysis oil. Independently of the objectives of the analysis, proper sample preparation is necessary to facilitate data processing after analysis. This includes, for example, the determination of the water content, which is important for the dilution of samples. None of the methods are capable of giving a complete analysis of the sample. A combination of GC and HPLC methods, together with the appropriate detection systems, is best suited for the chemical description of the pyrolysis oil sample.
