Analysis of the latter compounds could be accomplished by mass detection with target ion monitoring. The DB5 column is thus useful for the analysis of the chlorinated benzaldehydes and acetophenones.doi:10.1016/0021-9673(93)83314-ITerrence J. Smith...
To clarify the corresponding roles of Pd and Cu in this reaction, cyclic voltammograms (CV) experiments, Tafel analysis, and theoretical calculations were carried out. CV curves in different electrolytes could provide information about the catalytic properties of electrodes by tracking the processes invo...
The conversions were determined based on uncorrected integrals of the FID response in GC analysis. 2.2. BAL catalyzed C–C bond cleavage reactions In addition to the C–C bond formation capacity by BAL, it was found that BAL also catalyzed the cleavage of the C–C bond. Müller's group ...
aGC–MS analysis of products formed by PhBSα and PhBSβ subunits, and their mixture at 1:1 ratio. The response of internal standard in each run was set as 100%.bGC–MS analysis of products formed by PhBS from different hydroxycinnamoyl-CoA substrates. GC-MS chromatograms of in vitro enzy...

Irradiation products were identified by GC/MS analysis and their quantities were determined by GC analysis. Study of the reactants molar ratio effect indicates important aspects of the radiation chemistry of this system. It was observed that the yields of the major products increase as absorbed ...
benzaldehydecompound norethisterone enanthate injectionObjective: To establish a GC method for the simultaneous determination of benzyl alcohol and benzaldehyde in compound norethisterone enanthate injection.Methods: A capillary gas chromatographic method was carried out.An Agilent DB-WAX capillary column(30 m...
Besides, the practical feasibility of the CeO2NPs modified sensor has been demonstrated by amperometric method in various water samples. Before performing the real sample analysis, the collected water sample was filtered and removes the solid content. The standard addition method was used for the rea...
As a self-reactive substance, benzaldehyde oxime (BO) is prone to a highly exothermic runaway reaction and thermal hazard analysis and the reaction kinetics calculation of BO have great significance. In this work, the decomposition products of BO in nitrogen atmosphere were identified by GC鈥揗S...
As an internal standard in the meteorological chromatographic analysis procedure, acetophenone were chromatographically pure and purchased from Shanghai Macklin Biochemical Co., Ltd (Shanghai, China). O2 (99.99%) was provided by Maoming Deyuan Gas Company (Maoming, China). 4.2. Catalyst Preparation...
