Abstract Chemical imaging by Laser ablation – spark discharge – optical emission spectroscopy (LA-SD-OES) is presented. A low-energy laser pulse triggers an electric spark between a metal electrode tip and a sample and the excited plasma is analyzed by OES.

Abstract Glow discharge optical emission spectroscopy (GD-OES) was applied to quantification of Li in both positive and negative electrodes. Depth profiles of Li1.03Ni0.32Co0.33Mn0.32O2 (NCM) and hard carbon based electrodes in the range of state of charge (SOC) 0–100% were measured throughout from the surface to the current collector within a few ...

Analytica Chimica Acta, 2005
Abstract A novel type of interface for gas removal has been developed for coupling a high-temperature/high-pressure online flow digestion system to an ICP spectrometry instrument. It consists of a porous polypropylene tube with an inner rod made of PEEK which causes the formation of a thin film (100 μm) of liquid at the inner surface of the porous ...

Journal of Quantitative Spectroscopy and Radiative Transfer, 2013
Abstract Optical emission spectra of rich HMDSO/propane/air and propane/air flames (equivalence ratio Φ=1.33) were recorded using an imaging spectrometer in combination with an intensified CCD camera. The probe area was about 1×0.2 mm2. This is small for the OES signal and allows scans of high spectral and spatial resolution across the flame ...

Microchemical Journal, 2014
Abstract A new analytical method is proposed for the collection and quantification of gunshot residues (GSRs) from firearms using inductively coupled plasma optical emission spectrometry (ICP OES). Lead (Pb), barium (Ba) and antimony (Sb) concentrations in GSR from .38 caliber Taurus® handguns were monitored, and three important methodologies were ...

ECS Meeting Abstracts, 2016
Commercialization of many Li-ion cell chemistries is hindered by undesirable processes occurring during usage of Li-ion batteries, limiting their lifetime. One such process is the development of temperature gradients, especially in large-format cells, leading to uneven utilization of electrode material.1 Such inhomogeneity could locally accelerate or ...

Liquid steel samples were taken during ladle treatment and continuous casting of 37 heats of two duplex stainless steel grades. These samples were used to study inclusion characteristics and potential process control using the pulse distribution analysis with optical emission spectroscopy method (PDA/OES).
