PTR-MS Mass Spectrometer Detection of Buried Oil

Jean-Luc Le Garrec, J. Brian A. Mitchell,Stephane LeFloch and 2Ronan Jezequel
A novel type of mass spectrometer has been demonstrated to be capable of detecting oils buried in sand by direct sampling in real-time. Tests were first performed using oils placed at the bottom of a larger glass beaker and then systematically covered in sand. Oil samples were then buried on an artificial beach and subsequently detected. The technique has applications to oil detection on beaches and possibly in the arctic environment.

Soot Emission Reductions during In Situ Burning

. Ferrocene is a powerful smoke reducing catalyst that has been used as the basis for a clean burning open fire fuel. Results are presented from a meso-scale air sampling experiment that has demonstrated the effectiveness of the catalyst for reducing soot emissions from large fir
