Some interferences in ICP-AES
Thread Content
As far as I know there are 1. Spectral interference 2. Collective effect 3. Ionization interference. I don’t know what else you know? Let’s hear it
Spectral interference: Its main manifestations include background drift and partial or complete spectral overlap. matrix interference: The matrix can cause spectral interference and background drift, which is called the effect of the spectral matrix. Other matrix effects include: Sample atomization, atomic or ion form, excitation process of atoms or ions in plasma, etc. When the matrix composition of the sample is different from the standard solution, the matrix influence of these non-spectral line interferences will cause measurement errors. The matrix effects of non-spectral line interference can be divided into two categories:: One type is generated from the sample introduction system and the other is generated from the plasma.
