Help is a major group of PbS is divided into three parts: the sulfide minerals, crystalline phase of cubic crystal system.Due to its high lead content (86.6 wt. %), PbS is one of the most important lead ore, in history by the egyptians, the king of Babylon, and the Romans used.Like many sulfide, help directly with S K in EDS spectrum peak peak overlapping elements (Pb M series).Results in EDS spectrum diagram, the main very wide, and in the high-energy side another lower peak.By contrast, QUANTAX WDSCan clearly solved the corresponding spectrum of sulfur and lead in a single peak.Even when we need to use low kV analyzing small mineral particles, in order to ensure the high spatial resolution and low penetration depth, in WDSLow high-energy X-ray energy spectrum peak resolution is particularly important.
