Abstract:

Four mercury species (inorganic mercury, methyl-mercury, ethyl-mercury and phenyl-mercury) in shellfish muscle
were analyzed by high performance liquid chromatography-inductively coupled plasma-mass spectrometry (HPLC-ICP-MS). A
C18 reverse phase HPLC column was applied to separate four mercury species, and their concentrations were measured by using
ICP-MS through an external standard method. The method was optimized and the four mercury species could be effectively
separated within 15 min using gradient elution with methanol/ammonium acetate as the mobile phase. This developed method is
simple, efficient and sensitive, which can be suitable for determination of mercury species in shellfish muscle.

Key words: inorganic mercury, methyl-mercury, ethyl-mercury, phenyl-mercury, high performance liquid chromatography-inductively coupled plasma-mass spectrometry (HPLC-ICP-MS)
