摘要:
The invention relates to a device for sequentially measuring characteristics of a liquid-liquid or liquid-solid dispersed system contained in a main installation consisting of a serially mounted or derived circuit assembled thereon. Said circuit supplies, at a predefined rate, at least one measuring chamber (4) exposed to a collimated laser beam which strikes said chamber at normal incidence. The inventive device also comprises photodiode-type means (10A) for real-time measurement of a light signal which is back-scattered by the dispersed system sample circulating in the circuit and for converting said signal into an electric signal disposed near the circuit (3). The inventive device is characterised in that it is provided with means for real-time sequential measurement of the concentration of the diffusing particles of the sample of the dispersed system flowing in a circuit. Data on the measured concentration and data received from the photodiode-type means (10A) are transmitted to data capturing and processing means (13) for determining the distribution or spread of the sizes of the diffusing particles in the dispersed system.
摘要:
The invention relates to a method for the enzymatic extraction of chitin, characterised in that said method is carried out in a single step in which the chitin is obtained by the enzymatic hydrolysis of a raw material consisting of animal biomass including chitin, said enzymatic hydrolysis using an active enzyme in an acid medium. The invention also relates to a method for optimising said method for the enzymatic extraction of chitin. The invention also relates to the chitin that can be obtained by said enzymatic extraction method.
