The aggregation of two imidazolium-based ionic liquids, 1-ethly-3-methylimidazolium chloride (EMI(+)Cl(-)) and EMI(+) bis-(trifluoromethanesulfonyl)amide (EMI(+)TFSA(-)), in molecular liquids, water, methanol, acetonitrile, and benzene, has been studied by using the small-angle neutron scattering (SANS) technique. The SANS results have shown that the heterogeneity of EMI(+)Cl(-)-acetonitrile mi...

The complexation reaction between iodine and 1,10-Diaza-18-Crown-6 (DA18C6) has been studied in acetonitrile by spectrophotometric, biamperometric and conductometric techniques. The results are indicative of the formation of [(CH3CH)nI+.I¯3] from iodine and acetonitrile, and the formation of DA18C6 I+. I¯ from DA18C6 and [(CH...

acetonitrile used as a solvent in manufactures and affects to central nervous system from inhalation exposure. the aim of this study was to develop a micro-solid phase extraction method for  the determination of acetonitrile in the air matrix. the sampling was performed with a small diameter fused silica fiber coated with a thin film of stationary phase and was subsequently desorbed and analyze...

A method for the simultaneous determination in milk of the 50-mononucleotides adenosine 50-monophosphate, cytidine 50-monophosphate, guanosine 50-monophosphate, inosine 50-monophosphate and uridine 50-monophosphate and their corresponding nucleosides is described. Following deproteinisation, the sample extract was analysed by reversed-phase liquid chromatography, whereby chromatographic separat...

A high performance liquid chromatographic method for determination of Ethionamide (ETH) in human plasma was developed. The method involved deproteinisation of the sample with perchloric acid and analysis of the supernatant using a reversed-phase CN column (150mm) and a wavelength of 267 nm. The mobile phase consisted of Milli-Q water and Methanol (85:15, v/v) containing 0.05% Perchloric acid an...
