“…Guo et al 13 demonstrated that the size of the crater formed during ablative plasma formation can inuence detection sensitivity. Referenced pairs of emission lines for V (V I 440.85 nm and Fe I 438.35 nm), Cr (Cr I 425.43 nm and Fe I 425.08 nm) and Mn (Mn 476.64 nm and Fe 492.05 nm) were used to monitor elements present in trace amounts in a steel matrix.…”

“…4 However, compared with other well-established atomic spectral analysis techniques, conventional LIBS performs not well in sensitivity and precision. In order to improve the analytical performance of LIBS, a large number of methods have been investigated, such as double-pulse, 5 spark discharge, 6 plasma confinement, 7 and so on. These methods mentioned above don't require sample preparation but need a more complex experimental setup.…”

Abstract:In this study, a new approach for Laser-induced Breakdown Spectroscopy (LIBS) with gold nanofilm (NF) deposited on sample surface was carried out by using femtosecond laser. Different materials including metallic sample, semiconductor sample and dielectric sample were tested. Strong emission enhancement was obtained on SiO 2 , ceramic and Si sample. It was found that different lines in ceramic sample had different enhancement effect, which was probably related to concentration of different substances in ceramic. The enhancement effect was found to weaken with the increase of laser fluence. Enhancement factors of about 14 for SiO 2 , 5 for ceramic and 3 for Si sample were achieved at laser fluence of 3.3 J/cm 2 , which decreased to 9 for SiO 2 , 3 for ceramic and 1.5 for Si sample at laser fluence of 8.8 J/cm 2 . The mechanism of nanofilm-enhanced LIBS (NFELIBS) was localized surface plasmon resonance, which could change the dominant photon ionization process of sample.

“…There are several studies in which its accuracy and precision are addressed (Guo et al 2013;Axente et al 2014) and some techniques, for example, Double Pulse LIBS have actually contributed in improving these aspects (Harilal, Diwakar, and Hassanein 2013;Effenberger and Scott 2010;Khalil 2013).…”

Comparison of Single Pulse and Double Simultaneous Pulse Laser Induced Breakdown Spectroscopy

et al. 2014

A simple and cost-effective variant of laser induced breakdown spectroscopy is presented that involves a double simultaneous pulse configuration employing a single laser source. Its performance is compared with conventional single pulse configuration. Double simultaneous pulses were accomplished by splitting a Nd:YAG laser (1064 nm, 6 ns, 360 mJ) beam into two components that were focused on the sample surface to produce two concurrent breakdowns. Experiment was repeated for single pulse and double simultaneous pulses under different ambient pressures. The performance was evaluated on the basis of self-absorption, signal-to-noise ratio (SNR), and relative standard deviation (RSD) of the Mg II doublet (280.2704 nm, 279.553 nm). Optically thin emission lines of better profiles with higher signal-to-noise ratio resulted from double simultaneous pulses. The lowest relative standard deviations obtained by single pulse and double simultaneous pulse configurations were 18.89% and 12.01%, respectively. In fact, double simultaneous pulses have performed better than single pulse in all respects within the studied regime.
