The contribution of trace elements from smokeless powder to post firing residues.
The smokeless powders in 22 kinds of ammunitions seized from one of the Japanese gang groups were analyzed by scanning electron microscopy/energy dispersive X-ray microanalysis (SEM/EDX). Copper(Cu), sulfur(S), potassium(K), silicon(Si), aluminum(Al), calcium(Ca), iron(Fe), chlorine(Cl), and barium(Ba) were detected. Cu was found in all samples. One sample contained a high amount of Ba. One par...

Phytochemical analysis of Cyperus rotundus hexane fraction by GC-MS and total oligomeric flavonoid fraction by 4D GCXGC TOF-MS
Cyperus rotundus (CR) is a traditional medicinal herb, and recent studies demonstrated its pharmacological effects to cure neurological disorders. In our earlier reports, we also found that CR exerts anxiolytic effects and improves memory impairment in hypoxia-induced rats. In vitro CR also effectively ameliorates oxidative stress-induced SH-SY5Y neuronal cell damage. In the present study, we e...
متن کامل[Multiresidue method for determination of pesticide residues in processed foods by GC/MS/MS].
A rapid and simple multiresidue method has been established for determination of pesticide residues in processed foods by GC/MS/MS. The pesticides were extracted with ethyl acetate, and were cleaned up with a double-layered SPE cartridge column (graphite carbon black/PSA silica gel). Recovery tests of 258 pesticides from five kinds of processed foods (dumpling, curry, French fries, fried chicke...
