Objective: To approach the quantitative determination of Pb

As

Cu

Cd and Hg in efficacious on Heat Expelling and Enlightening Injection by inductively coupled plasma mass spectrometry.To probe into the quality control of heavy metal and hazard elements in Efficacious on Heat Expelling and Enlightening Injection. Method: The samples

digested via microwave

calibrated by internal standard elements such as Sc

In

Ge and Bi

with tea leaves as the controlled reference standard

were inlet into ICP-MS to analyze the quantity of Pb

As

Cu

Cd and Hg. Result: The correlative coefficients of the standard curves surpasses 0.997

with the recovery at 93.2%-100.3%

while their RSD was below 2.7%. Conclusion: The method is proved to be accurate and fast

seldom interfered

consultable for quality control of heavy metal and hazard elements in Efficacious on Heat Expelling and Enlightening Injection.
