Nowadays only little information (mainly by GC­MS) about the chemical nature of HTL oils is available. In the present work different standard and improved analytical techniques were tested as additional tools for the chemical characterization of HTL oils: analytical pyrolysis (Py­GC­MS), TGA and a novel stepwise Py­SPME­GC­MS were tested for the first time. By coupling these different techniques, we could establish the chemical nature of the fractions not amenable for standard oil analysis techniques (GC­MS,...
