Aug 05, 2021 · Since 1875, Shimadzu is pursuing leading-edge science and technologies in analytical and measuring instruments including chromatographs and mass spectrometers, medical devices, aeronautics, and industrial equipment.
Dec 01, 2019 · Using a static headspace gas chromatography–mass spectrometry method (HS-GCMS), this study performed a quantitative analysis of BTEXS levels in soils from Chinese rural areas in 2013 and 2016. The median ∑BTEXS concentrations in surface soils in 2013 and 2016 were 37.5 and 34.4 ng g −1 dry weight, respectively.
Sep 29, 2016 · THMs (chloroform (CHCl 3), bromodichloromethane (BDCM), dibromochloromethane (DBCM) and bromoform (CHBr 3)) in the water were measured by gas chromatography–mass spectrometry (GC–MS) by following USEPA method 551.1 (USEPA 1995a). Approximately 3.0 mL of methyl-tert butyl ether (MTBE) were added as the extraction solvent to 50 mL of the sample.
Jul 05, 2015 · The aim of this investigation was to enhance the quality of high free fatty acid olive oil (HFFAO). Silica gel (SG) was used as adsorbent by applying filtration and stirring techniques. Alkali treatments with NaOH and Ca(OH)2 were also conducted to neutralize high acidity of HFFAO. The levels of linoleic acid (C18:2) in neutralized oils were lower than in reference olive oil. Untreated and
Jun 14, 2021 · iGC- SEA or Inverse Gas Chromatography-Surface Energy Analyzer is an instrument that uses the iGC principle. The heart of its innovation is the patented injection manifold system which generates accurate solvent pulse sizes across a large concentration range, resulting in isotherms at unprecedented high and low sample surface coverages.

Gas chromatography is one of the fundamental analytical tools that compose the modern analytical lab, along with Mass Spectroscoy, Spectroscopy and Microscopy. However, like everything else, it does have several limitations, including lack of sensitivity, inability to tolerate water injections, and the sample must be in the vapor state.
Jun 01, 2015 · Gas chromatography coupled with pulse flame photometric detectors (GC-PFPD) was the most powerful technique introduced for the determination of sulphur species . This is because of the high sensitivity and selectivity that GC-PFPD can provide and it allows the determination of a wide variety of organosulphur species simultaneously [35] .
