A device for collecting contaminants from water samples is provided. The device includes a solid sorbent that collects and stores the contaminants from water samples. The solid sorbent is configured to allow for the preservation of the stored contaminants. The concentrations of the contaminants in the water samples are determined via analysis of the solid sorbent or via elution of the stored contaminants from the sorbent and analysis of the eluate solution.

System and method for preservation, transport, and analysis of water samples

Systems, devices, and methods for detecting contamination (e.g., bacteria) in fluid are provided. The systems, devices, and methods allow for filtering a fluid sample using a filter to capture and concentrate cells (e.g., bacteria) to detect electrochemical properties thereof. The cells can be exposed to a reagent that diffuses into the cells to produce a product of interest that can be used in analysis of the fluid sample. The product of interest can diffuse out of the filter into a fluid storage component for detection and analysis by an analysis component. After the sampling is completed, the filter can be detached and discarded. Other aspects of the present disclosure, including enhancements and various systems and methods for concentrating cells and analyzing the same, are also provided.
