Differentiële scanningcalorimeter (dsc) is een thermische analysemethode om de relatie te meten tussen het vermogensverschil en de temperatuur tussen het invoermonster en de referentie onder de geprogrammeerde temperatuurregeling. Het wordt vaak gebruikt om de smeltwarmte te meten, kristalliniteit en isotherme kristallisatiekinetiekparameters van polymeren, en om de glasovergangstemperatuur Tg te bepalen. Polymerisatie, genezen, verknoping, ontleding en andere reacties werden bestudeerd. De reactietemperatuur of reactietemperatuurzone, reaction heat and reaction kinetic parameters were measured.The measurement method of differential scanning calorimeter (dsc) is to place the sample in the furnace of the instrument, change the sample through a certain temperature control program, and draw the change curve of the material under the temperature change through the software, and then analyze the corresponding peak value change, obtain the corresponding measurement data, and analyze the characteristics of different materials. The operation is convenient and simple, while the precision is high, the measurement accuracy is high.

Differentiële scanning calorimeter dsc productintroductie

What are the advantages of differential scanning calorimeter dsc? The low temperature differential scanning calorimeter (dsc) of Nanjing Exhibition is listed. The method of semiconductor refrigeration is adopted, which can carry out low temperature test at -40℃, and the cooling speed is fast and the baseline is stable. Tegelijkertijd, the imported chip is used, which has high stability, and the color touch screen display, simple and fast operation, high display clarity, and the new furnace body color agent, high insulation, anti-interference, high temperature resistance. The instrument has two gas channels, which can be switched automatically. The gas size is controlled by the flowmeter.
