摘要(Abstract):

该实验探索建立差示扫描量热法鉴别珍珠粉和贝壳粉真伪。使用密封式铝坩埚封装样品,测定条件为升温速率10℃·min~(-1),样品量3 mg,氮气流速为40 mL·min~(-1)。结果表明珍珠粉及贝壳粉热焓值具有明显差异。该法可用于珍珠粉及贝壳粉鉴别,方法操作简便、结果准确。
The paper is aimed to establish a methods for identication of pearl powder and conch powder from different origins.Hermetic aluminum pan was used to encapsulate samples.The optimal testing conditions were;heating rate 10 ℃· min~(-1),sample weight 3 mg and nitrogen gas flow rate 40 mL·min~(-1).The enthalpy values of pearl powder and conch powder was obvious different.Identication of pearl powder and conch powder by DSC is a practical method for its accuracy,convenience and practificality.
