Hydrogen has been widely adopted as a carrier gas to replace nitrogen and helium in GC applications for a variety of reasons. Superior advantages include faster analysis, lower cost and the reliability of supply that hydrogen (generated on-site) offers. The purity of carrier gas is crucial for...
In this study, to explain the possibility of hydrogen transfer paths from manure to coal, Elbistan lignite (EL) combined with manure liquefaction of oil + gas products were analysed with Gas Chromatography-Mass Spectroscopy (GC-MS) and Nuclear Magn

2.2.7.2.2.1 GC-IRMS By performing a separation prior to isotope ratio analysis, hyphenated techniques such as GC-IRMS and LC-IRMS can provide isotopic analysis of a complex mixture, thereby providing additional information and higher discriminatory power. IRMS instruments require a somewhat steady str...
In order to further improve the output performance of EBFCs, the influences of electrode shape and array on the outputs of EBFCs were investigated by finite element analysis. The relationship between electrode shapes and the distribution of field strength and voltage were firstly explored by ...
Refining of Coal Liquid -Structural Analysis of Hydrogenated SRC-II Distillates with HPLC-GC/MS- In order to determine the effect of presulfurization of Ni-Mo-Al2O3 on hydrocracking of coal liquids, Wandoan coal SRC was hydrocracked in tetralin solvent... Sekiyu,Gakkaishi,Katsumori,... 被...
Fast GC analysis of major volatile compounds in distilled alcoholic beverages The principal secondary flavour compounds in distilled spirits can be successfully quantified by split injection to a 0.15 mm internal diameter (I.D.) capi... KM Namara,R Leardi,A Sabuneti - 《Analytica Chimica Acta》...
value of H2or O2production [124,140]. The practical amount of H2or O2production is detected through gas chromatography (GC) or the conventional water–gas displacement method, and the theoretically yield of hydrogen or oxygen is obtained via the chronoamperometric or chronopotentiometric analysis [...
(based on repeat analysis of lab air,n = 13) and are smaller than the symbols. The blue and black solid lines show different isotope effects that would be caused by fractionation (e) due to respiration (resp.). During consumption of O2by respiration (decreasing O2:Ar ratio), there ...
The time course of HDPE depolymerization over LSP-Z100 at 240 °C was studied by analysing the products using gas chromatography (GC), GC mass spectroscopy (MS) and by analysing the solid residues using elemental analysis, 13C MAS NMR, 1H NMR and glow discharge electrospray ionization (GD...
