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 ...
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 ...
Experimental and theoretical study of solubility of 1, 3, 5-trinitrohexahydro-S-triazine (Rdx) In alcohols
(2010)
The solubility of 1,3,5-trinitrohexahydro-s-triazine (RDX) in different alcohols were measured by HPLC, DSC, GC/MS, and NMR. The conformation of RDX in acetone-D6 solution was verified by vibrational studies using Raman ...
Cleaning validation applications using Mid-Infrared quantum cascade laser spectroscopy
(2017)
According to the Recall Root Cause Research (RRCR), an initiative governed by the U.S. Food and Drug Administration (FDA), the contamination of pharmaceutical products is an alarming cause of public concern. During 2015, ...
TNT and MO photodegradation in deionized and salt waters with visible light assisted by photoactivation of modified TiO2
(2020-05-22)
The release of munitions during military combat events or training exercises represents an alarming situation to the marine environment. Since nitroaromatic compounds (NACs) that are released from these weapons remain in ...
Separation, identification, and quantification of explosives using thin layer chromatography coupled to mid-infrared laser spectroscopy
(2019-05-10)
The need for rapid instrumentation and methods for detection and identification of chemical and biological threat agents in national defense and homeland security settings has become an ever more important issue in modern ...
