Nominal concentration: concentration calculated on the basis of the concentration of the prescribed reference and taking account of the prescribed correction factor. Witryna1 lis 1995 · Abstract. An analytic simple fluid theory (SFT) is derived to predict when a tokamak divertor should retain impurities. Only the simplest, one dimensional (1-D), case of leakage for ions from the point of ionization, along B to points far upstream, is considered. The SFT builds directly on earlier 1-D treatments of divertor retention of …

These two impurities correspond to [7-Dehydroalanine] sCT and its isomer, which was confirmed by MS/MS spectrometry as shown in Fig. 4. Such different retention times for the isomers have been achieved … Witrynapresent in the NaOCl followed by the reaction with Impurity 3 itself forms Impurity 11.
