Stationary phases. Part 39(1): Trace analysis of RDX in HMX on a novel copoly(vinylthiazole‐vinylimidazole) stationary phase by HPLC

TLDR
On decrit une methode d'analyse en phase liquide a haute pression (HPLC) for le RDX and le HMX avec une nouvelle phase stationnaire, le copoly (vinylthiazole-vinylimidazole) as discussed by the authors.
Abstract
On decrit une methode d'analyse en phase liquide a haute pression (HPLC) pour le RDX et le HMX avec une nouvelle phase stationnaire, le copoly(vinylthiazole-vinylimidazole). Les temps d'elution pour le RDX et le HMX avec cette phase stationnaire en utilisant du methanol/ eau (proportion 60/40 a 90/10) en tant que phase mobile donnent HMX > RDX, ce qui est tres different d'une phase RP-18 de type commercial. La selectivite chromatographique (valeurs α) entre RDX et HMX est de l'ordre de 2,40 a 2,55. Cet avantage peut etre utilise, lors de la synthese de HMX p. ex., pour detecter la presence de petites impuretes d'env. 1 ppm de RDX dans le HMX.

Determination of RDX and Keto-RDX in high-explosive mixtures by high-performance thin-layer chromatography

TL;DR: In this paper, high performance thin-layer chromatography (HPTLC) has been used for separation and quantification of components of high explosives containing hexahydro-1,3,5-trinitro (RDX) and 2-oxo-1.3, 5-triazacyclohexane (Keto-RDX or K-6) for online and off-line quality control of synthesis.

Separation of Conformers of Nitramines by High Performance Liquid Chromatography (HPLC)

TL;DR: A conformeric mixture of C3V and CS conformers of RDX and α- and β-conformers of HMX has been separated by High Performance Liquid Chromatography (HPLC) using a Nova-Pak RC18 column and MeOH-H2O mixtures as mobile phase.

Effect of alkyl chain length of the stationary phase on retention and selectivity in reversed-phase liquid chromatography : Participation of solvent molecules in the stationary phase

TL;DR: In this article, the retention behavior of various hydrocarbons, including n-alkanes, polynuclear aromatic compounds and alicyclic compounds, were examined on alkylsilylated stationary phases with trimthylsilyl (C1), octyldimethylsilyls (C8) and octadecyldimethyltimethyl silyl(C18) functionality.

Donor-acceptor complex chromatography (DACC) part II. Review of papers

TL;DR: In this article, the effect of chemical structure of donors and acceptors, temperature and solvent composition of the mobile phase on retention of donor-acceptor complexes is discussed. And the authors treat these examples, where donor or acceptor compounds are coated on or chemically bonded to a matrix.
