Trace impurity
SpletTypically, trace explosives analysis is qualitative and an assessment of method selectivity, e.g. matrix effects, suppression, etc. must be conducted as part of method validation. If a quantitative result is reported, it is good practice to identify all the components of uncertainty and make a reasonable estimation of its overall magnitude.

SpletThe impurity phases were analyzed by enlarging the XRD patterns. As shown in Fig. 2, there was no peak at the 2 θ range of 30°–33° in G1, however, at the oxygen partial pressure of 0.065 Pa (G2), two new peaks appeared at 31.14° and 33.09°, which were indicated by arrows. The new peaks could be indexed to the orthorhombic structure of Ga 2 Zn 6 O 9 … SpletAn impurity in a material is something that does not belong there. As the requirements for pure materials in demanding applications grow, so does the need to identify and measure …
SpletAn analytical method has been developed for the determination of trace impurities in high-purity uranium hexafluoride using liquid-liquid extraction of the uranium from the trace impurities followed by analysis with inductively coupled plasma-atomic emission spectroscopy. Detection limits, accuracy, and precision data are presented.
