The zinc-cadmium oxide (ZnO-CdO) nanocomposites with different weight percentages of cadmium oxide (CdO) nanoparticles were successfully synthesized by the sonochemical method using zinc and cadmium nitrates as precursors to probe their nano-structured surfaces for the decomposition reactions of chloroethyl phenyl sulfide (CEPS) as a surrogate of sulfur mustard agent simulant. Scanning electron...

A rapid simulated distillation method is described for analysis of petroleum fractions boiling within the range of ASTM D2887 [1]. The method employs an Agilent 6890N gas chromatograph (GC) equipped with a split/splitless inlet, flame ionization detector (FID), oven insert, and 3-meter 180-μm id capillary column. A SIMDIS software package is partially integrated into the GC ChemStation for data...

The chemical composition of oregano essential oil of different origin extracted from oregano plants grown in south-eastern Poland was analysed using the gas chromatography mass spectrometry (GC-MS) and gas chromatography flame ionization detector (GC-FID). The dominant compound was sabinene; its percentage proportion ranged from 10.85% to 25.46%, depending on the ecotype studied. Moreover, the ...

A new product (Application 460B-00) from Agilent Technologies/WassonECE uses a 5973N GC/MSD (gas chromatograph/mass selective detector) for the determination of trace levels of impurities that are moderate-to-low carbon-content such as oxygenates, mercaptans, sulfides, arsine, and phosphine in ethylene and propylene. This work describes the performance of Application 460B-00 with respect to lin...

The essential oil in leaves of Polygonum minus Huds., a local aromatic plant, were identified by a pipeline of gas chromatography (GC) techniques coupled with mass-spectrometry (MS), flame ionization detector (FID) and two dimensional gas chromatography time of flight mass spectrometry (GC x GC-TOF MS). A total of 48 compounds with a good match and high probability values were identified using ...

A new protocol was used to measure the quantity of reactive organic gases (ROG) being emitted from animal feeding operations (AFO) such as feed yards, dairies and poultry houses. The protocol makes use of a portable gas chromatograph (GC) that is brought to the field where actual measurements are taken in conjunction with the EPA flux chamber sampling protocol. To have the analyte concentration...
