In this work, a solid sampling device consisting of a tungsten coil trap, porous carbon vaporizer and on-line ashing furnace of a Ni-Cr coil was interfaced with inductively coupled plasma mass spectrometry (ICP-MS).A modified double gas circuit system was employed that was composed of carrier and supplemental gas lines controlled by separate gas mass flow controllers. For Cd determination in food samples using the assembled solid sampling ICP- Ms. the optimal ashing and vaporization conditions, flow rate of the argon-hydrogen (Ar/H2) (v:v 24:1) car- rier gas and supplemental gas, and minimum sampling mass were investigated. Under the optimized conditions, 10) Furthermore, the mean spiked recoveries for various food samples were 99.42-105.92 (n 6). The Cd concen trations measured by the proposed method were all within the certified values of the reference materials or were not significantly different from those of the microwave digestion method, demonstrating the good accuracy and precision of the solid sampling IcP-MS determination in food samples. o 2016 Elsevier B.V.
