【Abstract】 This paper studied the effects which were made on the determination of material purity by M-T 822 e differential scanning calorimeter(DSC). And five factors such as scanning rate, sample weight, thermo-resistance, pans and scanning technique, were discussed respectively. Result showed that scanning rate, thermo-resistance and scanning technique had some influences on the determination of purities, meanwhile sample weight and pans had little.更多还原
