Presentation transcript:

Experimental condition for LDI-time of flight analysis UltrafleXtreme MALDI-TOF/TOF MS (Bruker Daltonik GmbH, Bremen, Germany) equipped with the 355nm-1000Hz Nd:YAG laser was used to obtain mass spectra. The accelerating voltage and reflector detector voltage was set to 25kV and 2.6kV respectively. Each spectrum was produced from average of 200 ~ 1000 laser shots. Description on the difference between “hydrous pyrolysis” and the “in situ simulator” methods With the hydrous pyrolysis, source rock sample is heated with water to extract oils included in the rock sample. The sample used in this manuscript has been heated to 360 °C at a rate of about 6 °C/min. This is to generate oil by a procedure similar to the natural process. With the in situ simulator method, source rock sample is heated with water and the vapor generated during the process is collected with a specially designed gas/oil collector. Typically, the rock sample is heated to 360 °C at a heating rate of ∼ 3 °C/min.
