Abstract

The invention discloses a device for measuring diffusion performance of soluble gas in a hydrogel, comprising a sealing infiltration pond, wherein, a soluble gas sensor probe and a temperature sensor are hermetically fixed on the upper portion of the infiltration pond, the bottom of the infiltration pond is provided with a stirring paddle, a measuring chamber which can be able to provided with gel to be measured is arranged in the infiltration pond, and a constant temperature water-bath jacket is sleeved on the periphery of the infiltration pond. The device also comprises a computer which canbe connected with the signals of the soluble gas sensor, at least one constant temperature bottle connected with the infiltration pond through a three-way valve for preparing saturated gas solution, a thermostat connected with the temperature sensor in the infiltration pond, a magnetic stirrer, an N2 gas source, and a gas source of the gas to be measured. The invention solves the problems of easyleakage of the gas and big operation error in the mixing process of the gel and water.

Description

Technical field [0001] The invention relates to a device for measuring the diffusion performance of soluble gas substances in a hydrogel Background technique [0002] Hydrogel is a kind of packaging material widely used in fields such as microencapsulated organs and immobilized enzymes. As a nutrient necessary for cell metabolism, the diffusion of oxygen in hydrogel is the main factor that affects the activities of internal cells and enzymes; as a metabolite, the diffusion of carbon dioxide in hydrogel will also affect the cell state; other diffusion Reaction model, such as immobilized enzyme system, when gas participates in the reaction, the diffusion performance of gas molecules in the gel will directly affect the efficiency. Therefore, the diffusion performance of the soluble gas in the hydrogel is a very important performance of the hydrogel. At present, the diffusion coefficient is commonly used to measure the diffusion performance. At present, there are two main methods f...
