“…The light emissions from these excited species as they return to their ground state are measured using spectrophotometers. [18][19][20] LIBS provides numerous advantages as a monitoring technique such as minimal sample preparation, chemical free process, rapid detection, spatial information and portability as compared to the existing technologies of ICP-OES (Inductively coupled plasma -Optical emission spectrometry) and AAS (Atomic absorption spectroscopy). [21][22][23][24][25][26][27] Beef and beef offal, such as kidney have different contents of Na and K, which could be utilized by LIBS to develop quantification models for the same.…”

Laser induced breakdown spectroscopy for quantification of sodium and potassium in minced beef: a potential technique for detecting beef kidney adulteration. Analytical Methods, vol. 9, pg. 3314-3322. doi:10.1039/C7AY00757D Authors Y. Dixit, Maria Piedad Casado-Gavalda, R. Cama-Moncunill, X. Cama-Moncunill, Maria Markiewicz-Kȩszycka, Patrick Cullen, and Carl Sullivan Beef is a rich source of important minerals, with potassium (K) being the most abundant mineral quantitatively except in cured meats where Na from the added salt predominates. This study evaluates the potential of LIBS for quantification of the sodium (Na) and potassium (K) contents of minced beef as a potential method of detecting beef kidney adulteration. Additionally, the study aims at demonstrate the ability of LIBS to provide spatial mineral information of minced beef. A LIBS system was employed to collect spectral information of adulterated minced beef samples. Atomic absorption spectroscopy (AAS) was used to obtain reference values for Na and K. The chemometric technique of partial least squares regression (PLSR) was used to build the prediction models. Spatial mineral maps of minced beef samples were generated based on the predicted percentages of Na and K. The models for Na and K yielded calibration coefficients of determination ( 2 )

Development of a compact verticalcavity surface-emitting laser end-pumped actively Q-switched laser for laser-induced breakdown spectroscopy" (2016 This paper reports the development of a compact and portable actively Q-switched Nd:YAG laser and its applications in laser-induced breakdown spectroscopy (LIBS). The laser was end-pumped by a vertical-cavity surface-emitting laser (VCSEL). The cavity lases at a wavelength of 1064 nm and produced pulses of 16 ns with a maximum pulse energy of 12.9 mJ. The laser exhibits a reliable performance in terms of pulse-to-pulse stability and timing jitter. The LIBS experiments were carried out using this laser on NIST standard alloy samples. Shot-to-shot LIBS signal stability, crater profile, time evolution of emission spectra, plasma electron density and temperature, and limits of detection were studied and reported in this paper. The test results demonstrate that the VCSEL-pumped solid-state laser is an effective and compact laser tool for laser remote sensing applications. C 2016 AIP Publishing LLC.[http://dx

“…The instrumentation used in this work, LIBS and GC-MS, have been previously developed into portable systems for field sampling and are commercially available [Bednar et al, 2012;Liaud et al, 2014;Rakovský et al, 2014]. The results obtained through this research will aid law enforcement and environmental agencies in the detection of GSR and VOCs in contaminated air with faster analysis time and with the use of commercially available portable systems.…”
