China develops direct test for rareearth impurities_我的网站

A |     供应方面，上周国内PTA负荷环比提升1.9个百分点。PTA社会库存下降23.2万吨，PTA现货加工差走扩。    (ECNS) -- Chinese researchers have developed a method that can directly and precisely detect trace rare-earth impurities in high-purity rare-earth materials, overcoming a long-standing challenge caused by matrix interference, CCTV News reported Monday.    The breakthrough, led by a key laboratory under the State Administration for Market Regulation at Jiangxi University of Science and Technology, uses inductively coupled plasma tandem mass spectrometry (ICP-MS/MS). The technique eliminates the need for matrix separation, offering higher sensitivity, accuracy and faster testing.    The team has also made advances in sample pretreatment and instrument calibration. The technologies are already widely used by rare-earth producers and testing institutions to improve quality control and testing efficiency.                        。虹港石化两套共计500万吨计划本周重启，福海创450万吨、威联化学250万吨计划8月底重启。月底前仍有多套PTA装置计划重启，未来PTA负荷将进一步提升。需求方面，织造端部分秋冬面料新订单略有改善，江浙加弹、印染开工提升，织机开工持稳。聚酯负荷小幅下降0.2个百分点。聚酯环节继续减产，负荷缓慢下行。总之，地缘局势缓和，原油及P...。
