Time of Flight Mass Spectrometer (TOF-MS)

‚ÄčA custom-designed compact time of flight mass spectrometer (TOF-MS) has been acquired to couple with the shock tube for time-resolved measurements of species concentration. This system can operate at repetition rates as high as 150 kHz, providing a time resolution of a few microseconds. The shock tube end-wall is modified to incorporate a very small nozzle and skimmer arrangement that couples the shock tube to the TOF-MS. This system will complement the laser diagnostics by measuring time-histories of species that are not easily accessible with absorption spectroscopy. The picture below shows the KAUST TOF-MS system coupled to the KAUST low pressure shock tube facility:
