Deep Sea Biosphere Sample Fidelity Sampling Device
The ocean is the world's largest independent ecosystem, including deep seawater, surface sediments, cold springs, hydrothermal fluids, polymetallic nodules and other geological structures. 70% of seawater is in a high-pressure environment of more than 38MPa. Microorganisms in the deep sea biosphere account for 90% of the world's total microorganisms, and pressure resistance is their distinctive feature. At the same time, hydrothermal vents bring high temperatures and the flow of reducing substances such as hydrogen-rich and sulfides. Therefore, in order to conduct in-situ research on the deep sea biosphere in the laboratory, we need to solve a series of technical problems such as fidelity sampling, fidelity transfer, high temperature/low temperature fidelity culture under high pressure, and in-situ analysis. Our series of products can provide powerful assistance for research in this area.
Fidelity Sampling Fidelity Sampling Bottle:
Titanium alloy material;
500ml effective sampling volume:
120MPa maximum fidelity sampling pressure:
0~200"C sampling temperature range.
Pressure self-balancing system:
The volume of the buffer water collection tank is 500ml;
The pressure compensator balances the pressure changes in the sampling bottle during the ascent;
The bottle comes with a pressure sensor, with a working pressure of 0-120MPa, a pressure resolution of 0.1MPa, and a battery life of 10 hours.
Sampling Agency:
Used to fix and connect the above components to the lander, including the sampling valve release hook, sampling valve, one-way stop valve, etc.
Users can mount the fidelity sampling system through the multi-channel water sampling system, which shares the trigger mechanism with the multi-channel water sampling system. It is suitable for fidelity sampling at different depths in a dive mission. Time series sampling can also be performed, such as mounting a fidelity sampling system lander on the bottom, making it work continuously for one year, and opening a set of fidelity sampling bottles every month to collect samples. After one year, the mother ship recovers 12 sets of fidelity sampling systems for comparison.
