Real-Time, Geospatially-Resolved Atmospheric Contaminant Monitoring by Membrane Introduction Tandem Mass Spectrometry (MIMS-MS/MS) Near Oil and Gas Operations in Alberta, Canada

摘要

The 'lab-to-field' revolution is growing rapidly in the field of mass spectrometry as better portable systems become available. Real-time monitoring techniques such as Membrane Introduction Mass Spectrometry can provide continuous time series information that can be used for monitoring dynamic changes in contaminant concentration and to complement techniques involving sample collection for subsequent off-line measurements. However, in-field calibrations and data processing present some unique challenges. Real-time, geospatially resolved concentration plots in platforms, such as Google Earth promise to partially address this need. We have demonstrated this capability, using a portable MIMS-MS/MS system with real time data visualization to both investigate atmospheric contaminants (e.g. BTEX) near oil and gas operations in Alberta, Canada as well as to inform adaptive sampling strategies.
