Matrix effects in icp

Web28 sep. 2024 · Matrix effects are common in ICP-MS and may lead to either a suppression or an enhancement in the signal. Although not always well understood, matrix effects likely result from how easily an ionizable element affects the ability to ionize other elements. WebNon spectral interferences (matrix effects) were studied with 10percent nitric acid, 2percent methanol, for anICP multielemental solution and a hydro-organic matrix containing 70percent (v-v) acetonitrile in water,15 mmol Let8722;1 ammonium acetate and 0.5percent formic acid containing lanthanide complexes.
