The present invention relates to a lectin-macromolecular carrier coupling complex for separating glycosylated exosomes from a clinical sample, which comprises a macromolecular carrier and lectins coupled to the outer side of the macromolecular carrier. The complex may simply, conveniently, rapidly, and accurately separate glycosylated exosomes from a clinical sample with a high separation efficiency and a good repeatability; and the separated exosomes are intact in morphology without rupturing or cracking, may be directly used for liquid detection of glycosylated exosomes, or directly used for immunology-related detection, or directly used for gene detection or analysis after extracting related nucleic acids from the exosomes.

Sample processing methods and systems to collect a biological sample. A device may be configured collect a predetermined volume of a sample in sample chamber, and seal the chamber upon activation. The device may be further configured to mix the mix the sample with a predetermined volume of a reagent and/or mix the sample and the reagent in a pre-determined ration.

The present invention belongs to the field of gas solubility measurement, and provides a measuring device and method for gas solubility in a natural gas hydrate solution system. The measuring device mainly comprises a reaction system, a sampling system and a data analysis system. The present invention can be used for measuring gas solubility in a natural gas hydrate solution system at different temperature, pressure and salt ion conditions, and exploring influence of different environmental conditions on the gas solubility when hydrate-liquid water biphase equilibrium is achieved. The present invention in characterized in that the structure is simple, the operation is easy, sampling is carried out at a constant pressure to avoid damage to phase equilibrium and dissolution equilibrium of the systems, and a microfilter is used to ensure that a liquid sample taken does not contain hydrate crystals, so that experimental data has a relatively high accuracy.
