ICP-MS Determination of the Content of lead in rosin glycerides and hydrogenated rosin glycerides
A method was established to determine the content of lead in rosin glycerides and hydrogenated rosin glycerides by ICP-MS.After the samples was digested by microwave and re-moved most of the acid,it was analyzed.It could eliminate efficiently the jamming of various a-tomic and ion to lead by using the technique of collision and reaction pool.It used Internal stand-ard mixture as Bi,Rh elements to calibrate matrix interference and data drift.The results showed that this method had the advantages of low detection limit,high sensitivity,wide linear range,and rapid test.It could insure accuracy and stability of experimental data.It could also ac-cord with the demands of analysis for the content of lead in rosin glycerides and hydrogenated ros-in glycerides.
