Witryna26 paź 2009 · Purification of a 4N grade Cu rod by argon plasma-arc zone melting (APZM) was carried out. Detailed impurity analysis of the Cu rod was performed using glow discharge mass spectrometry (GDMS). Three impurity behavior groups based on segregation and evaporation during APZM were discussed using the GDMS analysis. … WitrynaThe reliable and accurate analysis of impurity peaks can also be achieved via mass spectrometry. During the above separations, the impurity peak (m/z) 278.4 amu, was examined. Figure 3 shows the SIR of the amitriptyline impurity on both the CORTECS C 18 +, 2.7 μm Column and the competitor solid-core C 18 column.
