| Abstract: | In this paper a new pulse sampling apparatus which can be operated in both the pulseintroduction and the conventional introduction is described.It has been used to determine fiveelements,Ca,Mg,Fe,Mn and Zn,in a traditional chinese medicine by flame atomicabsorption spectrophotomeny.The experimental results obtained have shown that satisfactoryanalytical results by two sampling methods can be obtained by using this device.The linearrange is about two times extended and the analytical speed and the precision increased.Besides,the sample quantity is greatly reduced. |
