Determination of methylmercury in the tuna tissue by High performance liquid chromatography with Inductively Coupled Plasma Mass Spectrometry
This study mainly applied one kind oftechnologies to determine the methylmercury in the tuna tissue with high performance liquid chromagraphy-inductively coupled plasma nlass spectrometry.We choosed the optmaum conditiom including that the mobile phase Was water with 5% methanol,2-mercaptoethanol,0.06mol/Lammomum acetate and pH6.8.The sample amount was 1OOuL and the flow rate was 0.4mL/min.The optimum checking conditions is that RF power was 1500W,integral time was 0.3s sampling depth Was 8.0mm,velocity of carrier gas Was 0.75L/min and velocity of auxiliary gas Was 0.40L/min.In this con~tiom.the calibration CUrVe was linear when the concentra tions od methylmercury was in the range of 0-4ug/mL(r=0.9996),the detection limit can achieve 9ng/L,RSD is 8.2%,and the addition recovery is 75%-97%.The results show this method is simple,rapid and sensitive and can be used for the daily analysis of tuna samples.
