In vitro approaches include: (1) recombinant enzymes such as cytochrome P450s and UDP-glucuronosyltransferases; (2) subcellular fractions, e.g. microsomes and liver homogenates; (3) hepatocytes; (4) liver slices [15] . The biological fluids make the analysis complicated. Since the enantiomers...
Processing all the detectors signals in a single software environment and in a uniform manner is a wish for most users. Tracking the quality of the results given by the instrument is a critical aspect to quickly validate or reject a given analysis. In many cases, it is also necessary to ...
a new procedure for the speciation of mercury in water based on the transformation of mercury (ii) and methylmercury (ii) into stable acetylides followed by hplc analysis 热度: GrapheneCeO2 hybrid materials for the simultaneous electrochemical detection of cadmium(II), lead(II), copper(II),...
Often the search for a new catalyst involves running an extensive number of reactions followed by chiral HPLC or GC analysis to determine its efficacy, which amounts to a very tedious undertaking. Recently, there have been many developments intended to increase the speed of this process by ...
XPS analysis was carried out on Au/ZrO2 to investigate the Binding Energy (BE) values of Au. In Fig. 5 the signal for Au (4 f) peaks are reported. In particular, the signal at higher energy is the 4 f5/2, while the signal at lower energy is the 4 f7/2. The area ratio...

The use of isotope pattern deconvolution analysis is proposed to simplify the double spiking species-specific isotope dilution result calculations when inter-conversion might occur. A detailed example is given for the determination of Cr(iii)/Cr(vi) in yeast by isotope dilution-HPLC-ICP-MS. The ...
In the case of 2,13-dicyano-[5]helicene (11) optical resolution was achieved by HPLC using a column packed with #gamma#-cyclodextrin. However, the enantiomers racemized within a few hours. On the other hand, the enantiomers of 28 turned out to be stable after separation on triacetyl...
