Online Membrane Sampling for the Mass Spectrometric Analysis of Oil Sands Process Affected Water-Derived Naphthenic Acids in Real-World Samples
Autor: Joseph Monaghan, Dylan Steenis, Ian J. Vander Meulen, Kerry M. Peru, John V. Headley, Chris G. Gill, Erik T. Krogh
Publikováno v: Separations, Vol 10, Iss 4, p 228 (2023)
Large volumes of oil sands process-affected waters (OSPW) result from heavy oil extraction in Alberta, Canada. Currently, a toxic legacy of ca. 500 Mm3 is stored in tailings ponds under a zero-discharge policy. OSPW is a complex mixture of suspended

A field portable membrane introduction mass spectrometer with in-line standard infusion and sample heat exchanger for real-time monitoring of volatile organic compounds in aqueous samples
Autor: Morten R. Martinsen, Nicholas G. Davey, Ryan J. Bell, Erik T. Krogh, Chris G. Gill, Øyvind Mikkelsen, Rudolf Schmid
Publikováno v: Environmental Chemistry and Ecotoxicology, Vol 2, Iss , Pp 168-174 (2020)
Maintaining a steady sample temperature when analyzing real-time samples in the field is crucial for Membrane Introduction Mass Spectrometry (MIMS). Diffusion through the membrane interface is temperature dependent, and sample temperature might vary

Publikováno v: Viruses, Vol 14, Iss 4, p 762 (2022)
Contamination of Pacific oysters, Crassostrea gigas, by human norovirus (HuNoV) is a major constraint to sustainable shellfish farming in coastal waters of the Northeast Pacific. HuNoV is not a marine virus and must originate from a human source. A b

Aqueous naphthenic acids and polycyclic aromatic hydrocarbons in a meso-scale spill tank affected by diluted bitumen analyzed directly by membrane introduction mass spectrometry
Autor: Joseph Monaghan, Qin Xin, Rebekah Aplin, Angelina Jaeger, Nicole E. Heshka, Lindsay J. Hounjet, Chris G. Gill, Erik T. Krogh
Publikováno v: Journal of hazardous materials. 440
With the increasing use of unconventional, heavy crude oils there is growing interest in potential impacts of a diluted bitumen (DB) spill in marine and freshwater environments. DB has the potential to release several toxic, trace organic contaminant

Direct, Isomer-Specific Quantitation of Polycyclic Aromatic Hydrocarbons in Soils Using Membrane Introduction Mass Spectrometry and Chemical Ionization
Autor: Chris G. Gill, Gregory W. Vandergrift, Erik T. Krogh
Publikováno v: Analytical Chemistry. 92:15480-15488
Polycyclic aromatic hydrocarbons (PAHs) are routinely screened for in soils, where quantitation of structural isomers is critical due to varying toxicity within PAH isomer classes. While chromatographic methods provide isomer resolution, such strateg

Condensed Phase Membrane Introduction Mass Spectrometry with In Situ Liquid Reagent Chemical Ionization in a Liquid Electron Ionization Source (CP-MIMS-LEI/CI)
Autor: Erik T. Krogh, Chris G. Gill, William Lattanzio-Battle, Gregory W. Vandergrift
Publikováno v: Journal of the American Society for Mass Spectrometry. 31:908-916
Direct mass spectrometry has grown significantly due to wide applicability, relative ease of use, and high sample throughput. However, many current direct mass spectrometry methods are largely based on ambient ionization techniques that can suffer fr
