The spray of desorbed analytes is intercepted by a second surface for subsequent analysis by several techniques. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=23136&type=Feature&page=1 Cobalt has been extracted from environmental and biological samples by dispersive LLME, following complexation with a nitrosonaphthol in a highly selective procedure that gives almost 100% efficiency. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=23013&type=Feature&page=1 A new fiber based on titania-chitin sol-gel coated on a silver wire was developed for the headspace solid phase microextraction of aliphatic alcohols from apple juice samples. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=23007&type=Feature&page=1 The volatile organic acids in cigarette tobacco have been determined by GC/MS following the combination of single drop microextraction and in-syringe derivatisation. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=22926&type=Feature&page=1 The routine storage of autopsied tissues in formalin leads to the leaching of any cocaine present into solution where it is hydrolysed to its metabolite benzoylecgonine. This process has implications for any subsequent forensic examination of the tissues. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=22892&type=Feature&page=1 Each step in the sample preparation for plant metabolomics - harvesting, drying, extraction and purification - has been reviewed in detail. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=22847&type=Feature&page=1 A nano-sized molecularly imprinted silica sorbent has been designed by Chinese scientists specifically for the adsorption of bisphenol A, but the technique is suitable for other compounds. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=22789&type=Feature&page=1 A simple but effective ultracentrifugation technique produces a protein fraction as well as DNA and RNA fractions from small amounts of tissue and will be useful for a combined approach to identifying molecular mechanisms in human tumours. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=22698&type=Feature&page=1 A QuEChERS method was evaluated for extraction of 16 PAHs from fish samples, with analysis of the extracts by LC with fluorescence detection. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=22746&type=Feature&page=1 The composition of human scent collected and stored as evidence for court cases is modified by the storage conditions, say US researchers, no matter which containers were employed. Glass containers stored in the absence of UV light provided the best conditions. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=22602&type=Feature&page=1 A novel dispersive extraction scheme involving three different liquid phases has been illustrated for the extraction of herbicides from tap and river water for HPLC analysis. It offers a rapid and environmentally friendly solution compared with other liquid-phase microextraction techniques. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=22540&type=Feature&page=1 Twenty-two methods of extracting faecal bacteria (enterococci and <em>Escherichia coli</em>) from sand were evaluated to recommend a standardized extraction technique. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=22534&type=Feature&page=1 A novel solid-phase device for trapping airborne methylated arsines that are emitted from soil revealed the extent of their evolution from paddy soils that had been treated with manure and flooded. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=22453&type=Feature&page=1 Thermal treatment has been evaluated for the preservation of the proteomes of post-mortem murine heart and brain tissue as an alternative to snap freezing. It had the most beneficial effect on the brain, reducing the degradation of high-molecular-weight proteins. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=22362&type=Feature&page=1 A method for the extraction of banned Sudan azo-dyes from foods for HPLC analysis used molecularly imprinted SPE with 1-(4-chlorophenyl)azonaphthalen-2-ol as the mimic template was tested for Sudan I, II, III, and IV. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=22366&type=Feature&page=1 US government scientists have helped to develop a heated SPME device for rapid air sampling which can mimic canine scent detection in real time. They hope to use the system to support canine findings, which are not currently accepted as evidence in court. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=22229&type=Feature&page=1 Cloud point extraction using a non-ionic surfactant has been used to remove PAHs, pesticides and drugs from solution for GC/MS analysis, using a post-extraction derivatisation step on the surfactants to ensure they pass cleanly through the column. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=22203&type=Feature&page=1 A novel technique involving the use of acoustic radiation forces and a micro-machined fluidic device is introduced for removing crystals from their growing solution for X-ray studies. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=22223&type=Feature&page=1 The tightly bound PAHs found on particulates produced in a light diesel engine can be extracted by SFE, say French researchers, who used a factorial experimental design to optimise the conditions and achieve near quantitative recoveries. http://www.separationsNOW.com/coi/cda/detail.cda?chId=1&id=22136&type=Feature&page=1 The extraction of trace elements from marine sediments has been accomplished in a few minutes using ultrasound focused in a glass probe. Recoveries were comparable to those from the recommended EPA method but are achieved in a fraction of the time.
