The high polarity of the column eliminates the need for multidimensional techniques and complex sample preparation. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=23012&type=Feature&page=1 Five diesel samples were analyzed by gas chromatography-mass spectrometry using six GC temperature programs, aiming to investigate the effect of temperature program on association and discrimination of the samples. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22975&type=Feature&page=1 Unexpectedly high levels of PAHs have been found in the house dust of ground-floor apartments in the USA which have associated asphalt parking lots that had been treated with a particular sealant. This dust presents a health risk to pre-school children who spend a lot of their time playing on the floor. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22925&type=Feature&page=1 The complete degradation of diseased swine carcasses in biosecure composting units, which cannot be opened for examination, can be confirmed by the GC/MS detection of three volatile organic compounds, say US researchers. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22891&type=Feature&page=1 This study was designed to develop a new diagnostic tool based on GC/MS that better discriminates between asthma and transient wheezing and that leads to a more accurate diagnosis and hence less undertreatment and overtreatment. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22806&type=Feature&page=1 The compounds responsible for the onset of the fishy, metallic off-flavour of human breast milk during storage have been characterised by German scientists using GC-O and 2D GC/MS. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22788&type=Feature&page=1 The composition of military fog used to obscure the battlefield in training exercises has been clarified by 2D gas chromatography, revealing that it consists primarily of aliphatic compounds. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22697&type=Feature&page=1 Headspace SPME combined with GC/MS was used to test the efficacy of foot deodorant formulations, identifying the main contributors to foot odour as acetic, butyric, isobutyric and isovaleric acids. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22653&type=Feature&page=1 A suspected chemical weapon with a foul smell causing serious nausea that was discovered at the residence of a European politician was revealed to be skunk spray, following a detailed GC/MS examination. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22601&type=Feature&page=1 The formation of nitrosamines in cooked ham cured with sodium nitrite is enhanced in the presence of free proline and pyrrolidine, say European scientists, although the amounts were not regarded as problematical if nitrite levels are kept within EU guidelines. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22539&type=Feature&page=1 The minimum aeration time for surgical oxygenators and tubing to ensure dissipation of the ethylene oxide used for sterilization was determined by GC and the use of Green Fluorescent Protein as a biosensor for ethylene oxide was evaluated. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22506&type=Feature&page=1 The use of nanofilm spray products, designed to apply self-cleaning or easy-to-clean coatings to a range of surfaces, is accompanied by the release of nanosized particles and VOCs into the air, some of which are not declared on the manufacturers' material safety data sheets. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22452&type=Feature&page=1 The transfer of PCBs from estuarine sediment to the biosphere via aquatic insects has been investigated by measuring their levels in the eggs and nestlings of the tree swallow, which feeds on the insects. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22361&type=Feature&page=1 A simple, fast and low toxic micro-scale procedure has been developed for determination of artemisinin in a single leaf or flower of living <em>Artemisia annua</em> using improved GC-ECD. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22349&type=Feature&page=1 Two derivatisation procedures have been evaluated by Italian researchers for the analysis of chiral amino acids in extraterrestrial missions searching for evidence of life in space. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22227&type=Feature&page=1 GC capillary columns coated with a series of lanthanide diketonate polymers have been prepared by scientists in the USA especially for the retention and separation of nitro-based explosives and TATP. The coating process involves the first reported use of azeotropic solvent mixtures for static coating a capillary column. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22202&type=Feature&page=1 A quantitative method for putrescine, spermidine and spermine in postmortem human brain tissue employing a novel extractive derivatization was used in an ongoing epidemiological study correlating these amines with the frequency of suicide. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22245&type=Feature&page=1 Differentiation of 21 glitter lip-glosses from seven manufacturers was attempted by pyrolysis gas chromatography/mass spectroscopy. Considering that lip-glosses are typically worn by young women, this study offers the potential of being able to provide investigative leads in sexual assault investigations. http://www.separationsNOW.com/coi/cda/detail.cda?chId=3&id=22191&type=Feature&page=1 The volatile compositions of 418 commercial samples of saffron have been measured using GC/MS and a discriminant analysis allowed clear differentiation according to the three ISO categories.
