“…With recent advances in broadband spectrometers and chemometric analysis techniques, the identification of non-metals has become increasingly widespread with LIBS. LIBS has been used for the identification of polymers (43)(44)(45)(46)(47)(48)(49)(50)(51)(52)(53)(54)(55)(56)(57), thermoplasts (58)(59)(60), and other organic compounds (61,62), including explosives (34)(35)(36)(37)(38)(39)(40)(41)(42)(63)(64)(65). Figure 4 shows the LIBS spectra of various thermoplastic polymers from McMaster-Carr acquired with a commercial LIBS system (Applied Photonics, Ltd).…”

“…These approaches, along with the use of clustering techniques [16][17][18][19][20]22 and spectral database searches, [10][11][12] have been evaluated and suggest promise. Recently, Schade and Bohling have proposed following the temporal emission decay of molecular bands of CN along with an artificial neural network approach to differentiate different explosive residues.…”

The present work describes the first quantitative molecular prediction using laser-induced molecular bands along with chemometrics. In addition, this spectroscopic procedure has demonstrated the first complete quantitative analysis utilizing traditionally insensitive elements for pharmaceutical formulations. Atomic LIBS requires certain sensitive elements, such as Cl, F, Br, S and P, in order to quantitate a specific organic compound in a complex matrix. Molecular LIBS has been demonstrated to be the first successful approach using atomic spectroscopy to evaluate a complex organic matrix. This procedure is also the first quantitative analysis using laser-induced molecular bands and chemometrics. We have successfully applied chemometrics to predict the formulation excipients and active pharmaceutical ingredient (API) in a complex pharmaceutical formulation. Using such an approach, we demonstrate that the accuracy for the API and a formulation lubricant, magnesium stearate, have less than 4% relative bias. The other formulation excipients such as Avicel Ò and lactose have been accurately predicted to have less than a 15% relative bias. Molecular LIBS and chemometrics have provided a novel approach for the quantitative analysis of several molecules that was not technically possible with the traditional atomic LIBS procedure, that required sensitive elements to be present in both API and formulation excipients.

“…There has been considerable progress over the last two decades to discriminate HEMs, chemical, and biological warfare samples using multivariate techniques and several other methodologies [10][11][12][13][14][15][16][17][18][19][20][21][22][23] . LIBS technique equipped with multivariate statistics has found intensive applications in the fields of explosives [13][14][15][16][17][18][19][20][21][22][23][24] , minerals [25][26] , and in pharmaceuticals [27][28] . Some research groups have successfully performed classification based on elemental intensity ratios obtained in the LIBS spectra [29][30][31] [AN] based on a ratiometric method.…”

A simple, yet efficient, methodology is proposed to classify three high energy materials (HEMs) with diverse composition using nanosecond laser induced breakdown spectroscopic data. We have calculated O/N, N/H, and O/H elemental peaks ratios using a ratiometric method. The present work describes a novel way to construct 1D, 2D, and 3D classification model using the above mentioned ratios. Multivariate statistical methods are followed for construction of the classification models. A detailed procedure for classification of three different HEMs is presented here.
