WitrynaThe impurity content present in the graphite-based anode material can have an effect on its stability, so the analysis and removal of trace impurity elements in the graphite-based anode material is particularly important. For instance, the presence of iron (Fe) is an important indicator for the efficiency of graphite anode materials. Witrynaimpurity is shown in Figure 2 versus impurity content. At low impurity concentration (x = 0.01 to x = 0.03 for Fe and to x = 0.02 for Co) we got a negligible cell magnetization. At such low concentrations Co and Fe are non-magnetic. The average magnetization of im-purities versus impurity content is shown in Figure 3. As was discussed in our ...

Witrynaimpurities, containers, sample preparation devices, volatile organics introduced as a result of handling personal care products, and even columns themselves. Plasticizers from labware can interfere with LC-MS, resulting in the need to lengthen the chromatography run in order to resolve these peaks from analyte peaks. Witrynaisﬁed for impurities randomly distributed on the regular iron sites [6–8]. Therefore one can attempt to separate volume and conduc-tion band (chemical bonds) modiﬁcation effects due to addition of impurity provided the volume effect is calculated by using ab initio methods for the pure iron. In order to do so one has to calculate the
