In situ vapor generation inductively coupled plasma spectrometry for determination of iodine using a triple-mode microflow ultrasonic nebulizer after alkaline solubilization

Analytical Methods, 2010
The analytical potential of a coupled continuous-microflow ultrasonic nebulizer triple-mode micro-capillary system (µ-USN/TCS) for the determination of iodine in biological samples by direct iodine vapor generation inductively coupled plasma optical emission spectrometry (VG-ICP-OES) has been investigated.

Investigation and quantification of spectroscopic interferences from polyatomic species in inductively coupled plasma mass spectrometry using electrothermal vaporization or pneumatic nebulization for sample introduction

Spectrochimica Acta Part B: Atomic Spectroscopy, 1998
Abstract A new method for quantification of spectral interferences based on analyte isotope ratio measurements in the presence of various concentrations of a specific matrix is presented. Within the method, a tolerance level is used, defined as the matrix concentration at which the ratio between analyte isotopes with and without interferences is ...

Ultrasonic Nebulization, Multimode Sample Introduction System for Simultaneous Determination of Hydride-Forming, Cold Vapor, and Non-Hydride-Forming Elements by Microwave-Induced Plasma Spectrometry

Spectroscopy Letters, 2014
ABSTRACT A novel synergic effect of ultrasonic nebulization (USN) and a multimode sample introduction system (MSIS) when used in combination has been exploited for efficient generation of conventional hydride-forming (As, Bi, Ge, Sb, Se, Sn), Hg vapor, and non-hydride-forming (Ba, Ca, Li, Mg, Sr) elements. The ultrasonic nebulizer supplied a microliter

Sensitive determination of Hg together with Mn, Fe, Cu by combined photochemical vapor generation and pneumatic nebulization in the programmable temperature spray chamber and inductively coupled plasma optical emission spectrometry

Talanta, 2017
Continuous photo-induced generation of mercury cold vapor has been successfully coupled with conventional pneumatic nebulization in programmable temperature spray chamber (PCVG-PN-PTSC) allowing fast, sensitive and easy multi-element analysis. The applied technique enabled simultaneous determination of non-volatile forming elements (Fe, Cu, Mn) and ...

Microplasma Optical Emission Spectrometry with MWCNT-Assisted Extraction and Ultrasonic Nebulization-Enhanced Photochemical Vapor Generation for Sensitive Determination of Trace Heavy Metals in Seafood

Analytical Chemistry
Field analysis of heavy metals in seafood is crucial for assessing the hazards and potential risks associated with human exposure to heavy metals through dietary intake. However, a low analyte concentration and complex pretreatment procedures pose significant challenges for microplasma-optical emission spectrometry (OES).
