An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the “as collected” condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (i.e. mixture of soil, vegetation, and / or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and / or chemical properties of the sample. The sample preparation and chemical analysis sub-systems can be used to analyze soil, vegetation, and / or manure samples. A soil collection system is disclosed which captures and directs samples to the sampling system for processing.

This invention discloses a vertical chromatography detection device with self-aspiration sampling capability, relating to the field of material analysis by determining the chemical properties of materials. It includes a sampling component and a storage component. The sampling component includes a detection tube with a buffer tube and a capillary tube at its sampling end. The buffer tube has an annular groove around its periphery. A chromatography test strip is installed inside the detection tube, and the sample application end is located inside the buffer tube. The storage component includes a storage tube, a base, and a seal. The storage tube has a frustum-shaped flange on the outer side of its port and a seal. The base has multiple limiting plates inside, at least two of which have protrusions. The storage tube is embedded between the limiting plates, and the frustum-shaped flange is inverted onto the protrusions. When the buffer tube and capillary tube are inserted into the storage tube, the annular groove covers the outside of the frustum-shaped flange. This invention utilizes a capillary tube to achieve self-aspiration sampling and uses the storage component to pre-store and release diluent, making operation simple.

The invention relates to a method for manufacturing a microfluidic valve, comprising: providing a substrate (1) of a mechanically inert material, mechanically inert over time with respect to one or more physico-chemical properties, the substrate (1) being configured with a structural part of the valve; printing, by additive layer manufacturing, a series of one or more filaments (2) of a material, mechanically responsive over time with respect to one or more physico-chemical properties, and preferably a LCP, the series of filaments (2) being configured with a functional part of the valve; and providing the series of filaments (2) on the substrate (1), configuring a fluid flow rate (3) through the valve by applying an anti-adhesion treatment on one or more interfaces of the filaments (2) and the substrate (1). In this way, a change in one or more physico-chemical parameters causes a sequential disruption of the LCP molecules, contracting or expanding their polymer chains in the longitudinal or transverse direction of the filaments (2), and causing an increase or decrease in the fluid flow rate (3).

The application provides a method and system for simulating the physical and chemical coupling of atmospheric diffusion under a nuclear and chemical integrated accident scene. The method first constructs a parameterized model of a nuclear and chemical integrated source term, determines the distribution ratio of nuclides on particles of different chemical properties according to the physical characteristics of nuclides and the release rate of chemical components; then runs the aerosol dynamics coupling evolution operator to monitor the concentration of hazardous chemicals and the relative humidity in the simulation space in real time, calculates the particle size change and density change of the nuclide carrier aerosol in the diffusion process; based on the evolved physical parameters, the settling term in the atmospheric diffusion equation is corrected in real time, and the dynamic diffusion distribution of radioactive nuclides in three-dimensional space is deduced by using the iterative step method; finally, the ground pollution correction map and the synergistic damage evaluation results under the nuclear and chemical integrated accident are output in combination with the chemical and radiation synergistic factors. The application solves the problem of diffusion prediction distortion caused by the neglect of the physical and chemical interaction in the traditional model, and improves the accuracy of complex disaster consequence evaluation.
