Abstract
|
|
|
|
In this study, the hydride vapour generator inductively coupled plasma mass spectrometry (HVGICPMS) was applied as the new analytical method to show the high accurate and reproductive data analysing the amounts of selenium and germanium being existed inside a system of plant. In order to decrease the interference effects, such as ion and molecular interference. Mini torch was used into the ICPMS instead of the conventional torch. At conditions of the different kinds and concentrations of acid solution, the different reductive conditions for composing hydride, and the different methods for making ash, the contents of selenium and germanium in lettuce were analysed. The inspection of yields and data comparison from SRM-1574 and -1570a were used for increasing the accuracy of this analysis.
