MRI: Acquisition of Trace Metal Analysis Instrumentation

北密歇根大学化学系将获得一台冷蒸气汞分析仪和电感耦合等离子体光学发射分光光度计（ICP-OES）、一台高压液相色谱仪、一台微波消解系统和相关的采样设备，这些设备来自主要研究仪器（MRI）项目。这将促进有关环境主题的各种研究项目，包括1)监测地表水质量和与硫化物采矿活动有关的金属的生物积累研究；2)磁共振显像剂中金属离子的毒性研究；3)测量聚二甲基硅氧烷化合物（pdms）帮助金属通过细胞膜运输的能力；4)监测铁矿石化学成分，提高采矿过程中铁的回收率；5)通过对鹿湖鱼类和其他水生生物汞形态的分析，研究汞的毒性；6)定量比较低、高金属环境下小龙虾体内金属硫蛋白水平。冷蒸气汞分析仪和电感耦合等离子体光学发射分光光度计（ICP-OES）用于痕量水平（ng/L）的多元素金属分析，用于环境，生物，工业，法医，地质和毒理学研究。它被用于世界各地的分析实验室。每年约有50名本科生或研究生将通过课程作业和研究项目接受ICP-OES技术培训。这些设备将增强该机构作为区域企业、组织和其他机构的资源的能力。

The Chemistry Department at Northern Michigan University will acquire a cold vapor mercury analyzer and inductively coupled plasma optical emission spectrophotometer (ICP-OES), a high pressure liquid chromatograph, a microwave digestion system and related sampling equipment with this award from the Major Research Instrumentation (MRI) program. This will facilitate various research projects on environmental topics including 1) monitoring surface water quality and bioaccumulation studies of metals associated with sulfide mining activity; 2) toxicity studies of metal ions involved in magnetic resonance imaging agents; 3) measuring the ability of polydimethylsiloxane compounds (PDMSs) to aid in the transport of metals through cell membranes; 4) monitoring iron ore chemistry to improve iron recoveries during mining processes; 5) studying mercury toxicity by mercury speciation analysis in fish and other aquatic life from Deer Lake; and 6) quantifying and comparing metallothionein levels in crayfish living in low and high metal content environments.A cold vapor mercury analyzer and inductively coupled plasma optical emission spectrophotometer (ICP-OES) is used for multi-elemental metal analysis at trace levels (ng/L) for environmental, biological, industrial, forensic, geological, and toxicology studies. It is used in analysis labs across the world. Approximately 50 undergraduate or graduate students per year will be trained in ICP-OES techniques through course work and research projects. The equipment will enhance the institution''s ability to serve as a resource for regional businesses, organizations, and other institutions.
