Abstract
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.
Claims43
A device for collecting and releasing contaminants from water samples comprising:
- at least one solid sorbent that is capable of adsorbing target contaminants, preserving the target contaminants for extended periods of time, and releasing the target contaminants for subsequent analysis;
- means for supporting or containing the at least one solid sorbent and facilitating rapid adsorption of the contaminants;
- and
- a package for storing the at least one solid sorbent with adsorbed contaminants.
A device for collecting and releasing contaminants from fluid samples comprising:
- at least one solid sorbent that adsorbs and releases target contaminants,
- means for supporting or containing the at least one solid sorbent and facilitating rapid adsorption of the contaminants;
- and
- a package for storing the at least one solid sorbent with adsorbed contaminants.
A method of collecting and releasing contaminants from water samples comprising:
- providing a water sampling device having at least one solid sorbent;
- exposing the device to a sample of water;
- allowing the at least one solid sorbent to adsorb one or more contaminants from the water;
- removing the device from contact with the water;
- releasing the one or more contaminants from the at least one solid sorbent at a later time;
- and
- performing analysis on the released contaminants.
A method of collecting and releasing contaminants from water samples comprising:
- providing a fluid sampling device containing at least one solid sorbent;

- allowing the at least one solid sorbent to adsorb one or more contaminants from the fluid,
- removing the device from the fluid;
- releasing the one or more contaminants from the at least one solid sorbent;
- and
- performing analysis on the one or more contaminants.
