introduction
there are two instruments in our lab – icp-oes and icp-ms,with full automatic, high precision and high sensitivity.the icp-oes can be used to determine the major elements in geological samples. the icp-ms can be used to determine the minor elements in geological samples,the elements/ca ratio of foraminifer shell, also the zircon u-pb dating.
1. inductively coupled plasma optical emission spectrometeres
type：iris advantage
origin: made in german thermofisher

function：it is mainly used to test major elements in geological samples.
precision: <0.5%
2. inductively coupled plasma mass spectrometer
type：vg-x7
origin: made in german thermofisher
beginningtime：2003
function：it is mainly used to test minor elements in geological samples, the elements/ca ratio of foraminifer shell, also the zircon u-pb dating.
precision: <2%
