“…2.4.5 Laser induced breakdown spectroscopy. Although the use of LIBS for water analysis remains hampered by the lack of sensitivity, hardware commonly used elsewhere in atomic spectrometry such as USN 119 or HG 120 have now been combined with LIBS in an attempt to boost sensitivity. Alternative approaches advocated the use of absorbents such as printing 121 or lter paper 122 in an attempt to preconcentrate water samples.…”

“…The measured LOD for Mg can be as low as 0.242 ppm. The same technology was used by Aras et al (2012) to detect Na, K, Mg, Ca, Cu, Al, Cr, Cd, Pb, and Zn. Jet flowing method (Lee et al 2011;Cheri and Tavassoli 2011;Feng et al 2010;Yueh et al 2002) is another simple but effective method; instead of directly focusing the laser inside a bulk liquid sample, the liquid is allowed to flow as a continuous thin jet stream, and the laser can be focused on the water column to generate more effective and stable plasma.…”

Water quality monitoring is a critical part of environmental management and protection, and to be able to qualitatively and quantitatively determine contamination and impurity levels in water is especially important. Compared to the currently available water quality monitoring methods and techniques, laser-induced breakdown spectroscopy (LIBS) has several advantages, including no need for sample pre-preparation, fast and easy operation, and chemical free during the process. Therefore, it is of great importance to understand the fundamentals of aqueous LIBS analysis and effectively apply this technique to environmental monitoring. This article reviews the research conducted on LIBS analysis for liquid samples, and the article content includes LIBS theory, history and applications, quantitative analysis of metallic species in liquids, LIBS signal enhancement methods and data processing, characteristics of plasma generated by laser in water, and the factors affecting accuracy of analysis results. Although there have been many research works focusing on aqueous LIBS analysis, detection limit and stability of this technique still need to be improved to satisfy the requirements of environmental monitoring standard. In addition, determination of nonmetallic species in liquid by LIBS is equally important and needs immediate attention from the community. This comprehensive review will assist the readers to better understand the aqueous LIBS technique and help to identify current research needs for environmental monitoring of water quality.

“…Detection limits of 40 mg L −1 [6], and 100 mg L −1 Pb [14] were reported for experiments on liquid-jet and in bulk water analysis, respectively. In our previous work [25], a detection limit of 13.6 mg L −1 Pb was obtained from a LIBS system that utilize an ultrasonic nebulizer to produce sub-micron size aerosols. An LOD value of 1.3 mg L −1 Pb obtained in this study by the HG-LIBS technique, presents 10 times enhancement compared to that of by ultrasonic nebulization sample introduction system.…”

“…Electrospray ionization [22,23] and proper nebulization techniques like pneumatic and ultrasonic nebulization also widely used to introduce liquid samples in the form of an aerosol [24,25]. Recently, analysis of liquids based on hydride generation sample introduction technique with laser-induced breakdown spectroscopic detection, HG-LIBS, for some of the hydride forming elements have been shown [27][28][29].…”

A laser induced breakdown spectrometry hyphenated with on-line continuous flow hydride generation sample introduction system, HG-LIBS, has been used for the determination of arsenic, antimony, lead and germanium in aqueous environments. Optimum chemical and instrumental parameters governing chemical hydride generation, laser plasma formation and detection were investigated for each element under argon and nitrogen atmosphere. Arsenic, antimony and germanium have presented strong enhancement in signal strength under argon atmosphere while lead has shown no sensitivity to ambient gas type. Detection limits of 1.1mgL-1, 1.0mgL-1, 1.3mgL-1 and 0.2mgL-1 were obtained for As, Sb, Pb and Ge, respectively. Up to 77 times enhancement in detection limit of Pb were obtained, compared to the result obtained from the direct analysis of liquids by LIBS. Applicability of the technique to real water samples was tested through spiking experiments and recoveries higher than 80% were obtained. Results demonstrate that, HG-LIBS approach is suitable for quantitative analysis of toxic elements and sufficiently fast for real time continuous monitoring in aqueous environments.Izmir Institute of Technology; Scientific and Technological Research Council of Turkey (BAP-12 109T327
