Egg yolk lecithin samples were digested by microwave and 15 kinds of metal elements in it were determined by inductively coupled plasma mass spectrometry(ICP-MS). The detection conditions were optimized and the methodology was investigated. The results showed that under the conditions of RF power 1.55 kW, flow rate of carrier gas(high purity argon)1.03 L/min, flow rate of plasma gas 15.0 L/min, peristaltic pump speed 0.1 r/s, sampling depth 10 mm and 3 replications, the internal standard solution with Sc,Ge,In and Re were added online for matrix effect and interference correction, and Au was added when determining the content of Hg to reduce the test error. The linearities for the 15 elements of the method were good with the correlation coefficients(R)above 0.999. The detection limit and quantitation limit of 15 elements were 0.03-0.65 ng/mL and 0.10-1.97 ng/mL, respectively. The precisions of the instrument were good with RSD in the range of 0.45%-4.67%. The RSD of the repeatability test was in the range of 1.78%-8.72%.The RSD of the intermediate precision was in the range of 2.24%-9.45%. The recovery rate of the 15 elements was in the range of 92.67%-132.90% with RSD in the range of 1.42%-7.00%. The stability of the sample solution was good and when it was stored at 2-8 ℃ for 72 h, RSD was in the range of 0.56%-3.93%. The method had advantages of fastness, accuracy and high sensitiveness, and it could be used for simultaneous determination of 15 kinds of metal elements in egg yolk lecithin. |
