Gas chromatography-mass spectrometry instruments were interfaced to high-pressure flow-through microreactors to monitor the product formation on-line. Three types of instrumental setup are described illustrating the versatility of this kind of coupling. The first example shows the thermal and catalytic conversion of dibenzyl ether in solution under 155 bar hydrogen atmosphere. In the second application, thermal decomposition of JP-7 jet fuel was carried out under supercritical conditions to study the gaseous product evolution. This system features the application of a microbalance to monitor the weight of the total liquid sample plus products. The third system was designed to perform conversion of solid sample (wood) in liquid/vapor environment. This reactor can be applied to model two-step liquefaction processes with catalytic conversion of the primary product. All three systems provide information on the product distribution and kinetic profiles of the conversion processes.
