“…The absolute limits of detection achievable with LIBS are also far from unacceptable; they are already in the picogram-femtogram range and are soon expected to be further improved by signal enhancement and sub-micrometer sampling techniques. The comparison of the microsampling LIBS with bulk-sampling methods is often also meaningless, but nevertheless it has been repeatedly proved that LIBS can provide similar accuracy to that of either bulk-solid sampling (AAS, ICP-OES, XRF, and ICP-MS [64, [114][115][116]) or solid microsampling (μ-XRF, LA-ICP-MS [117][118][119]) methods, with the added benefit of being portable and available for remote measurements, etc. The calibration-free method of analysis (CF-LIBS), developed by Tognoni et al [120], is probably the quantitative method that has generated the most interest in the LIBS community over the years.…”

Laser-induced breakdown spectroscopy (LIBS) has become an established analytical atomic spectrometry technique and is valued for its very compelling set of advantageous analytical and technical characteristics. It is a rapid, versatile, non-contact technique, which is capable of providing qualitative and quantitative analytical information for practically any sample, in a virtually non-destructive way, without any substantial sample preparation. The instrumentation is simple, robust, compact, and even enables remote analysis. This review attempts to give a critical overview of the diverse progress of the field, focusing on the results of the last five years. The advancement of LIBS instrumentation and data evaluation is discussed in detail and selected results of some prominent applications are also described.

“…For some elements, there could be nonlinear effects at higher mass loadings as were seen for Na in Figure 7. the atomic concentration in the plasma volume and then reaches a plateau due to line-width broadening and self-absorption (Gornushkin et al 1999;Panne et al 2001;Meissner et al 2004). This nonlinear relationship between atomic concentration and LIBS signal intensity is more pronounced for resonance lines such as Na I line used in this study.…”

A new approach has been developed for making near-real-time measurement of elemental composition of aerosols using plasma spectroscopy. The method allows preconcentration of miniscule particle mass (pg to ng) directly from the sampled aerosol stream through electrostatic deposition of charged particles (30-900 nm) onto a flat-tip microneedle electrode. The collected material is subsequently ablated from the electrode and monitored by laserinduced breakdown spectroscopy. Atomic emission spectra were collected using a broadband spectrometer with a wavelength range of 200-980 nm. A single-sensor delay time of 1.3 µs was used in the spectrometer for all elements to allow simultaneous measurement of multiple elements. The system was calibrated for various elements including Cd, Cr, Cu, Mn, Na, and Ti. The absolute mass detection limits for these elements were experimentally determined and found to be in the range of 0.018-5 ng. The electrostatic collection technique has many advantages over other substrate-based methods involving aerosol collection on a filter or its focused deposition using an aerodynamic lens. Because the particle mass is collected over a very small area that is smaller than the spatial extent of the laser-induced plasma, the entire mass is available for analysis. This considerably improves reliability of the calibration and enhances measurement accuracy and precision. Further, the aerosol collection technique involves very low pressure drop, thereby allowing higher sample flow rates with much smaller pumps-a desirable feature for portable instrumentation. Higher flow rates also make it feasible to measure trace element concentrations at part per trillion levels. Detection limits in the range of 18-670 ng m −3 can be achieved for most of the elements studied at a flow rate of 1.5 L min −1 with sampling times of 5 min.

“…The unique features of laser radiation together with the ease of transmission of the optical analytical signal predisposes LIBS for in-situ and remote analysis and make this technique competitive with other spectrometric methods [6]. With its multi-elemental capability and spatial resolution, LIBS is regarded as a complementary technique to inductively coupled plasma mass spectrometry with laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) [7] or spark source optical emission spectrometry [8]. In addition to the benefits associated with direct solids analysis, LIBS can also be applied to the analysis of liquids [9][10][11].…”
