Abstract
Various aspects of the present disclosure are directed to methods and systems for in-situ accumulation of one or more substances from a liquid environment. In one embodiment of the present disclosure, a method is disclosed including placing a cartridge with a sorbent in the liquid environment, driving a liquid volume through the sorbent, and repeating the act of driving as a function of time.
Claims13
A method for in-situ accumulation of one or more substances from a liquid environment, the method including the steps of:
- placing a frame arrangement comprising a shell, a chamber, and a cartridge with an inlet in the liquid environment, wherein the shell at least partly surrounds the cartridge and the cartridge comprises a sorbent, wherein the sorbent is adapted for accumulating a specific substance or a specific group of substances, wherein the shell has diffusion gaps for diffusion of liquid from the liquid environment into the shell, such that the inlet of the cartridge is in direct contact with the diffused liquid from the liquid environment;
- driving a liquid volume through the sorbent by negative pressure;
- and
- repeating the act of driving as a function of time.
A system for in-situ accumulation of one or more substances from a liquid environment, the system comprising:
- a frame arrangement comprising a shell, and a cartridge with an inlet, wherein the frame arrangement is configured for supporting an actuator configured to drive a spindle defining a displacement axis, the spindle coupled to a flange, wherein the shell at least partly surrounds the cartridge, the cartridge comprises a sorbent adapted for accumulating a specific substance or a specific group of substances, and wherein the shell has diffusion gaps for diffusion of the liquid from the liquid environment into the shell, such that the inlet of the cartridge is in direct contact with the diffused liquid from the liquid environment;
- the flange configured for a displacement along the displacement axis, the flange supporting a piston crown configured to operate in a chamber;
- the chamber defining a chamber volume as a function of the piston crown, the chamber having means for being secured to the frame arrangement, and being in a liquid connection with the cartridge, wherein the act of driving a liquid volume through the sorbent by negative pressure is performed by changing a volume of the chamber having an initial chamber volume;
- and
- a means configured and arranged to
- repeat the act of driving as a function of time.
