content of ultra-trace se in biological samples has been directly measured by hg-afs, after the sample was digested by closed pressured or wet digestion technique.
样品经密闭高压或常压湿法消解后,氢化物-原子荧光光谱法直接测定了生物样品中痕量硒。
the result obtained by using wet digestion was lower than the actual content. microwave digestion was not suitable for determination of total arsenic in shrimp powder.
the method of microwave digestion, ash digestion, wet digestion and acid circulating reflux are compared, the difference are not significant between any two methods ( p >0,05).
we have the capabilities of preparing samples from ashing to wet digestion to microwave digestions.
微波辐射在样品制备领域已成功应用多年,是消解方法中的最佳选择。
a comparison was made between microwave digestion and wet digestion methods for the determination of pb in bulgy food with faas. and being concentrated by apdc-ddtc-mibk system extraction.
