| Abstract: | A method for the determination of 22 elements in human gastric tissue by ICP-MS with microwave digestion was develpoed.In the proposed method,the gastric tissue samples were treated by constant temperature drying equipment.Under the optimized conditions,the samples were analyzed by ICP-MS after microwave digestion in HNO3-H2O2 solution system.Ge and Rh were used as internal standard elements to calibrated the influences of matrix effect and signal drift on measurement.The recoveries of the studied elements ... |
