Journal ArticleDOI
Elucidation of C2 and CN formation mechanisms in laser-induced plasmas through correlation analysis of carbon isotopic ratio
Meirong Dong,Meirong Dong,George C.-Y. Chan,Xianglei Mao,Jhanis J. Gonzalez,Jidong Lu,Richard E. Russo +6 more
TL;DR: In this article, a comparison of the experimental observed isotopic patterns in the molecular emission with the theoretical statistical pattern was made to clarify the formation mechanisms of C2 and CN molecules during laser ablation of organic materials.
Journal ArticleDOI
Investigation of matrix effects in inductively coupled plasma-atomic emission spectroscopy using laser ablation and solution nebulization - Effect of second ionization potential
TL;DR: In this paper, a new kind of matrix interference was found in inductively coupled plasma (ICP)-atomic emission spectrometry using both laser ablation and solution nebulization as sample introduction techniques.
Journal ArticleDOI
Multiple emission line analysis for improved isotopic determination of uranium — a computer simulation study
George C.-Y. Chan,Xianglei Mao,Inhee Choi,Arnab Sarkar,Arnab Sarkar,Oanh P. Lam,David K. Shuh,Richard E. Russo +7 more
TL;DR: In this article, the authors used laser induced breakdown spectroscopy (LIBS) to simulate isotopic analysis of a single U line and found that analytical performance primarily depended on the signal-to-background ratio (SBR) and net intensity of the emission line.
Journal ArticleDOI
Plasma-related matrix effects in inductively coupled plasma - Atomic emission spectrometry by group I and group II matrix-elements
George C.-Y. Chan,Wing-Tat Chan +1 more
TL;DR: In this article, the effects of Na, K, Ca and Ba matrices on the plasma excitation conditions in inductively coupled plasma-atomic emission spectrometry (ICP-AES) were studied.
Journal ArticleDOI
Laser ablation molecular isotopic spectrometry of water for 1D2/1H1 ratio analysis
TL;DR: In this article, a multivariate PLSR (Partial Least Squares Regression) based calibrations were carried out and validated using multiple statistical parameters using two spectrometers having two orders of magnitude difference in spectral resolution.
