Separation is unaffected by the proportions of the two components, which lends itself to industrial application. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=26430&type=Feature&page=1 An effervescent tablet boosts a dispersive extraction procedure by rapidly increasing the contact area between analytes and absorbent, say Spanish researchers, who demonstrated this novel approach for the removal of nitroaromatic compounds from water. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=26409&type=Feature&page=1 In a study of the effects of sampling volume and time on platelet quality, it was concluded that sampling for pO<sub>2</sub> determination should be carried out in small volumes and assessed within 30 min of collection to obtain reliable and comparable results. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=26382&type=Feature&page=1 The poppy alkaloid thebaine has been extracted from various matrices by electromembrane extraction in a rapid process with high enrichment factors for subsequent HPLC analysis. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=26300&type=Feature&page=1 The major compound responsible for the characteristic aroma of patchouli oil has been extracted in high yield from the plant by microwave-assisted ionic liquid treatment. The process should be applicable to medicinal plants in general for the extraction of active components. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=26270&type=Feature&page=1 To determine the influence of pooling strategies and spatial variations on detected soil bacterial communities, 45 soil cores were sampled each from a eucalypt woodland, a sown pasture and a revegetated site in an Australian landscape and compared. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=26240&type=Feature&page=1 Multiwalled carbon nanotubes have been magnetised for the dispersive solid-phase extraction of nerve agents and their marker compounds from environmental waters. The technique is more rapid than SPE and is effective in muddy waters without prefiltration. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=26184&type=Feature&page=1 A combined SPE-dispersive liquid-liquid microextraction method has been used for the first time to extract a series of organo-phosphorus pesticides from drinking water and well water for subsequent GC/MS analysis with remarkably low limits of detection. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=26163&type=Feature&page=1 Organophosphorous pesticides including dichlorvos, diazinon, malathion, phenamiphos and chlorpyrifos, were extracted from water samples by pneumatic nebulization single-drop microextraction for GC/MS analysis, with recoveries of 75.2 to 105.3%. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=26084&type=Feature&page=1 Melamine and cyanuric acid have been measured in non-dairy creamer by HPLC following online enrichment by microdialysis in the first direct chromatographic method for these two food adulterants. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=26037&type=Feature&page=1 Sampling of human hand scent for forensic purposes has been tested using contact and noncontact methods with four types of fibrous material, as an aid to acquiring the most representative and reproducible scent profile of an individual for canine searching and detection. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=26020&type=Feature&page=1 A molecularly imprinted stir bar was prepared using bensulfuron-methyl as the template molecule and methacrylic acid as the functional monomer for the removal of trace levels of bensulfuron-methyl analysis from tap water, soil, and soybean for HPLC-UV analysis. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=25994&type=Feature&page=1 Planar SPE has been devised as a novel, automated approach for the efficient extraction of pesticides from foods, with almost complete elimination of the matrix effects which blight alternative procedures. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=25934&type=Feature&page=1 A multiple headspace SPME procedure using a novel coated fibre has been described for the removal of the toxin ethyl carbamate from alcoholic drinks for subsequent gas chromatographic analysis. It achieves complete recovery, so eliminating any matrix effects. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=25891&type=Feature&page=1 An empirical correlation for predicting enhancement factors has been developed for packed liquid-liquid extraction columns, giving good agreement with experimental data for toluene/acetic acid/water and <em>n</em>-butyl acetate/acetic acid/water systems.
