Determination of 137Ba Isotope Abundances in Water Samples by Inductively Coupled Plasma-optical Emission Spectrometry Combined with Least-squares Support Vector Machine Regression

A simple and rapid method for the determination of 137Ba isotope abundances in water samples by inductively coupled plasma-optical emission spectrometry (ICP-OES) coupled with least-squares support vector machine regression (LS-SVM) is reported. By evaluation of emission lines of barium, it was found that the emission line at 493.408 nm provides the best results for the determination...

Use of Ion-molecule Reactions in Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to Improve Selenium Analysis Accuracy and Detection

Bulk Chemistry Of

Introduction: MIL 03346 is a nakhlite which has been recently recovered from Miller Range in Antarctica [1]. The Meteorite Working Group (MWG) allocated us a 0.5 g rock chip for a chemical study. We have determined the concentrations of 45 elements using a combination of ICP-AES (inductively coupled plasma-atomic emission spectrometry) and ICP-MS (inductively coupled plasma-mass spectrometry) p...

Selective Separation and Preconcentration of trace Amounts of Gallium in Water and Rice Samples using Cloud Point Extraction and Determination by Inductively Coupled Plasma-Atomic Emission Spectrometry

In the present study a cloud-point extraction process using non-ionic surfactant Triton X-114 for selective extraction of gallium from aqueous solutions was developed. The method is based on the complex formation of Ga (III) with N, N′ -bis (salycilidene)-1, 2-phenylenediamine (salophen) as a chelating agent in buffer media of pH 5. After phase separation and dilution of the surfactant-rich pha...

Nano-particle labelling of nucleic acids for enhanced detection by inductively-coupled plasma mass spectrometry (ICP-MS).

Oligonucleotides containing a biotin functionality were successfully labelled with a streptavidin nanogold conjugate and subsequently separated and analysed by high performance liquid chromatography-inductively coupled plasma-mass spectrometry (HPLC-ICP-MS).
