“…We have collected a number of references dealing with various aspects of liquid-LIBS studies and applications. 482,,–542 Cremers et al 482 first characterized the detection of several elements in aqueous solutions with “repetitive single spark” and “repetitive spark pairs” operation: the problems encountered were clearly outlined but the analytical potential of the approach was also evident. This paper paved the way to further developments in liquid-LIBS analysis.…”

“…Liquid-to-solid transformation . Examples are the work of Cáceres et al 502 (simple quick-freeze method to detect trace metal ions in ice); Pardede et al 504 (electrochemical deposition as thin film on a nickel plate electrode surface; electrode placed in a vacuum chamber is the LIBS target); Díaz-Pace et al 526 (liquid converted into a solid pellet of calcium hydroxide by mixing with CaO); Schmidt and Goode 509 (pre-concentration and immobilization on a membrane; membrane is the LIBS target); Sarkar et al 533 (filter membrane base collection and LIBS); Jijón and Costa 541 (steel surfaces scratched with an HB pencil; 1.0 μL salt solution deposited; high hydrophobicity produces homogeneous spot collecting the dried material); and Vander Wal et al 211 (1.0 mL solution deposited onto a carbon planchet and evaporated).…”

Laser-Induced Breakdown Spectroscopy (LIBS), Part II: Review of Instrumental and Methodological Approaches to Material Analysis and Applications to Different Fields

2012

View full text Add to dashboard Cite

The first part of this two-part review focused on the fundamental and diagnostics aspects of laser-induced plasmas, only touching briefly upon concepts such as sensitivity and detection limits and largely omitting any discussion of the vast panorama of the practical applications of the technique. Clearly a true LIBS community has emerged, which promises to quicken the pace of LIBS developments, applications, and implementations. With this second part, a more applied flavor is taken, and its intended goal is summarizing the current state-of-the-art of analytical LIBS, providing a contemporary snapshot of LIBS applications, and highlighting new directions in laser-induced breakdown spectroscopy, such as novel approaches, instrumental developments, and advanced use of chemometric tools. More specifically, we discuss instrumental and analytical approaches (e.g., double- and multi-pulse LIBS to improve the sensitivity), calibration-free approaches, hyphenated approaches in which techniques such as Raman and fluorescence are coupled with LIBS to increase sensitivity and information power, resonantly enhanced LIBS approaches, signal processing and optimization (e.g., signal-to-noise analysis), and finally applications. An attempt is made to provide an updated view of the role played by LIBS in the various fields, with emphasis on applications considered to be unique. We finally try to assess where LIBS is going as an analytical field, where in our opinion it should go, and what should still be done for consolidating the technique as a mature method of chemical analysis.

“…Laser-induced breakdown spectroscopy (LIBS) has been used in industrial (Brech and Cross, 1962;Noll et al, 2001;Palanco and Laserna, 2000;Sturm et al, 2004;López-Moreno et al, 2005;Kraushaar et al, 2003), biomedical (St-Onge et al, 2004;Samuels et al, 2003;Dixon and Hahn, 2005;Samek et al, 2001), archeological (Melessanaki et al, 2001(Melessanaki et al, , 2002Anzano et al, 2002Anzano et al, , 2005Muller and Stege, 2003;Pouli et al, 2005;Lopez et al, 2005;Lazic et al, 2005;Oujda et al, 2005), geological (Fabre et al, 2002;Harmon et al, 2005;Vadillo and Laserna, 1996), and environmental (Harmon et al, 2006;Wainner et al, 2001;Gondal et al, 2006;Pace et al, 2006;Gondal and Hussain, 2007;Anzano et al, 2006) applications. LIBS has been used to identify polymers by various strategies, including (1) correlating the LIBS spectrum of the unknown with library spectra (Gornushkin et al, 2000;Anzano et al, 2006), and (2) using artificial neural networks (Sattmann et al, 1998).…”

Rapid characterization of analgesic pills by laser-induced breakdown spectroscopy (LIBS)

et al. 2009

This work presents two rapid and effective methods for the identification of analgesic pills. LIBS spectra from pills in the 200-1,000-nm spectral window were compared with reference spectral libraries stored by computer. The libraries consisted of representative spectra from various groups of analgesic pills samples. The forms of emission spectra of paracetamol, ibuprofen, and acetylsalicylic acid were studied. Simple statistical correlation methods including linear correlation were used. Also LIBS spectra from pills in the 200-1,000-nm spectral window were analyzed to obtain the C:C 2 :H:N:O ratios. These ratios could be used to sort the three most used analgesic pills. Simple calibration curves with the studied ratios are sufficient to classify correctly the analgesic pills studied. These techniques can be useful for the identification of analgesic pills.

“…It has attracted substantial attention nowadays for a wide range of applications such as measuring of the microelements in solids, liquids and gases and for discrimination of microorganisms and bacteria [1][2][3][4]. It is a relatively new task to use the LIBS technique in plant samples [5][6][7].…”
