A water sampling device has a rigid body, a top lid, extension members, a horizontal member, a spring, a rod, at least one polymer membrane and a bottom lid. The top lid has a shaft attached to it and the shaft traverses through the horizontal member. The bottom lid is connected to the rod upon which the at least one polymer membrane is attached perpendicularly. The water sampling device undergoes two different stages of lid opening and closing while in operation of collecting water sample to concentrate diversified bacteria from different water depths. The top lid, the shaft and the spring co-operate with the rigid body and the horizontal member such that in a first state, the top lid seals the top end opening while in a second state allows fluid to flow to an inside portion of the rigid body.

A device for multi-parameter integrated monitoring of a deep submarine turbidity current primarily includes cement pile pore-pressure monitoring, optical turbidity monitoring, floating ball flow velocity monitoring, and turbidity current sediment sampling, can observe the turbidity, excess pore pressure, flow velocity, and other parameters of the turbidity current, can fulfill simultaneous and real-time transmission for in-situ monitoring, and can complete multiple tasks at the same observing position, so that the situation where the sampling position and the observing position are different due to the movement of an apparatus along with a ship during ordinary work is avoided.

A method for recovering an acidic gas, includes: a step of bringing a gas to be treated that contains an acidic gas into gas-liquid into contact with an amine absorbing solution, allowing the amine absorbing solution to absorb the acidic gas, thereby removing the acidic gas from the gas to be treated; a step of allowing the amine absorbing solution that has absorbed the acidic gas to release the acidic gas, thereby regenerating the amine absorbing solution, and at the same time, recovering the released acidic gas; and an analysis step of calculating concentrations of iron ions and/or heavy metal ions in the amine absorbing solution.

In an embodiment, a method of detecting nanoparticle contamination in a processing chamber includes removing a first component from the processing chamber subsequent to a processing operation; and measuring first nanoparticles from the first component using spICPMS, comprising: separating the first nanoparticles from a first surface of the first component by: exposing a first portion of the first surface to a first exposure surface of a first liquid medium; and mechanically manipulating the first liquid medium.

A testing system for measuring loss of soil particles with different particle sizes in a water inrush process includes: a vibration screening apparatus; a water collecting apparatus for collecting the mass of water and transmitting the water to a collecting and calculating apparatus; a conveying apparatus for conveying screened soil particles to a weighing apparatus; a weighing apparatus used for weighing the screened soil particles and transmitting the measured weight of the screened soil particles to the collecting and calculating apparatus; and a collecting and calculating apparatus used for controlling the operation of the testing system, inputting parameters and calculating data. The condition of particle loss in a simulated tunnel water inrush process can be automatically measured in real time, providing a basis for researching the influence caused by the particle sizes of fillings in the water inrush process of the tunnel to water inrush.

An apparatus for obtaining samples from a process, and which can be located in the process, which comprises a gate which reciprocates between a first position and a second position to fill and empty a sample chamber via corresponding inlets and outlets. The gate may pivot within the chamber about a longitudinal axis through the chamber, and a dam prevents fluid flow directly between the inlets and outlets. The inlets may provide outlets, and vice versa, depending on the direction of movement of the gate. Means such as pumps may be provided to agitate the fluid samples obtained by the apparatus, and sensors mounted in the sample chamber (for example on the gate or on the dam) can perform measurements on the samples. Wipers may be provided on the gate to assist in the ingress and egress of samples into and out of the sample chamber. It is also possible to inoculate the fluid samples within the sample chamber.

A method for active or passive sampling of particles and gas phase organic and non-organic components in a fluid flow (4) is disclosed, wherein said method comprises the step in which a sampling device comprising a first denuder device (1), a filter device (3), and a second denuder device (2), arranged in axial direction in a series in said order, is provided at a measurement spot, wherein the first denuder device (1) and the second denuder device (2) each is hollow and contains surfaces provided with a hydrophobic and/or a hydrophilic sorbent, or said second denuder device (2) contains a packing of hydrophobic and/or hydrophilic sorbent particles, as well as a sampling device used in said method.

An optical measurement instrument is an integrated instrument that includes an optical cavity with a light source, a sample cuvette, and an optical sensor. The light source and sensor are on a bench that is on a translational or rotational mechanical platform such that optical beam can be moved to multiple sample containers. Each sample containers holds a distinct microorganism-attracting substance and a portion of a fluid sample containing an unknown microorganism. Each distinct microorganism-attracting substance is configured to bind with a single type of microorganism. The unknown microorganism in the fluid sample binds with the distinct microorganism-attracting substance in a single sample container. The instrument incubates the microorganism in the single sample container and detects the presence of the microorganism in the single sample container to thereby simultaneously identify the unknown microorganism.
