摘要：
An approach for the detection of hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) was presented by using laser surface photofragmentation-fragment detection spectroscopy. The technique uses an ultraviolet laser to photolyze RDX and a second 226-nm laser to ionize the resulting NO photo-fragment. It was stated that a detection threshold of ∼14 ng/cm2 is determined at 1 atm and room temperature with 10 μJ to 20 μJ of photolysis and a probe laser energy.
