Abstract
ICP robustness increases with increasing programmable spray chamber temperature while MIP robustness decreases for the PCVG-PN-PTSC-ICP/MIP-OES technique.
Highlights
Coupled plasma (ICP-OES) and microwave induced plasma optical emission spectrometry (MIP-OES) are commonly used for trace elements determination in aqueous solutions
In spite of having a lot of advantages, pneumatic nebulization (PN) suffers from low sample transport efficiency to the plasma (1–3%) resulting in relatively high limits of detection (LODs) by ICPOES.[1,2,3]
The most spectacular changes are observed for ne and Trot
Summary
Coupled plasma (ICP-OES) and microwave induced plasma optical emission spectrometry (MIP-OES) are commonly used for trace elements determination in aqueous solutions. In these two spectroscopic techniques, pneumatic nebulization (PN) is preferentially used as a liquid sample introduction technique. Several heated spray chamber systems have been investigated. Peredes et al.[4] described the effect of heating of a torch integrated sample introduction system (TISIS) on analytical gures of merit by ICP-OES.
