Abstract:
A cartridge sampler for collecting a target species from an environment for subsequent chemical analysis includes removable collection media having at least one molecule sensor thereon. The cartridge sampler includes a means for tagging a geospatial location and time that the fluid samples are provided to the collection media such that the location and time that the fluid samples are provided to the collection media can be later determined. Also disclosed are systems and methods for collecting species from various environments including a subsurface formation, a pipeline, and gaseous, soil or sub-slab, and aqueous environments. The cartridge sampler is fitted on or within a device designed for moving within each environment.
