Fourier transform infrared mapping to determine the distribution of active ingredients in pharmaceutical formulations
(2007)
A basic problem in pharmaceutical manufacturing is that a relatively simple formulation can produce widely varying therapeutic performance depending upon how the ingredients are distributed in the final matrix. Many methods ...
Standoff raman spectroscopy system for detection of explosives, chemical warfare agents simulants and toxic industrial compounds
(2008)
In this work a remote Raman system has been designed, assembled and tested for detecting explosives, Toxic Industrial Compounds (TIC) and Chemical Warfare Agents Simulants (CWAS) at laboratory scale up to 7 m target-telescope ...
Enhanced Raman Scattering of TNT on nanoparticles substrates: Ag, Au and Au/Ag Bimetallic colloids prepared by reduction with sodium citrate and hydroxylamine hydrochloride
(2007)
Surface-Enhanced Raman Scattering (SERS) provides extremely high sensitivity, due to increase in the Raman cross-sections of intrinsically very weak scattering events making these events comparable or even better than ...
Desarrollo de método cuantitativo para la determinación del contenido de humedad en el proceso de granulación de un medicamento utilizando la tecnología de infrarrojo cercano
(2011)
The granulation process is one of the most important processes in the manufacture of a pharmaceutical product. This is due to that in this manufacturing step the active ingredient (AI) is mixed with the excipients. One ...
Preparation and study of thin RDX films standards on various substrates deposited by spin coating technology
(2017-05)
The highly energetic material (HEM) hexahydro-1,3,5-trinitro-s-triazine, also known as RDX, has two stable conformational polymorphs at room temperature: α-RDX (molecular conformation of –NO2 groups: axial-axial-equatorial) ...
Detection and discrimination of high explosives on human hair by Raman scattering
(2020-05-29)
High explosives (HE) represent a high risk to the safety and health of the general population. Therefore, there is an ongoing demand for methods of analysis with limits of detection at trace levels for these hazardous ...
Quantum cascade laser-grazing angle spectroscopy detection of high explosives deposited on various substrates using air spray
(2020-04-19)
The mid-infrared (MIR) laser reflectance of samples of high explosives (HEs) deposited on reflective and matte substrates using spray deposition was measured and used to generate multivariate (MVA) models for the analysis ...
Standoff laser-Induced thermal emission of explosives
(2013)
A laser mediated methodology for remote thermal excitation of analytes followed by standoff infrared (IR) detection is proposed. The goal of this study was to determine the feasibility of using laser induced thermal emission ...
Experimental and Dft Studies of the mechanism of cetone-peroxide formation reaction using Raman and nuclear magnetic resonance spectroscopies
(2009)
A mechanism for the reaction between acetone and hydrogen peroxide leading to the formation of the important homemade explosive Acetone Peroxide is postulated. The proposed mechanistic scheme is based on Raman and Nuclear ...
Dependence of active mode remote Ft-Ir sensing on angle of incidence, substrate type and analyte surface concentration
(2013-12)
A standoff detection scheme for a highly energetic material (HEM) and other threat chemicals deposited on substrates as contamination residues using Fourier transform infrared spectroscopy (FTIR) is described. The HEM used ...
