少年派的奇幻漂流China develops direct test for rare earth impurities_我的网站
一 | (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. 今天，第九批在韩志愿军烈士遗骸交接迎回安葬工作正式启动。9月15日，中韩双方将共同举行烈士遗骸装殓仪式；9月16日，中韩双方将举行志愿军烈士遗骸交接仪式，随后空军运-20接“第九批在韩志愿军烈士遗骸回国”；9月17日，将在沈阳抗美援朝烈士陵园举行安葬仪式。 。
