Inductively Coupled Plasma Mass Spectrometer

Atomic Spectroscopy is a foundational technique for laboratories aiming to analyze a broad range of elemental concentrations in a myriad of sample matrices. The Center for Applied Energy Research (CAER) at the University of Kentucky installed an Inductively Coupled Plasma - Optical Emissions Spectrometer (ICP-OES) in 2006. Over the years, sample sizes and requested detection limits have become smaller and our system cannot meet the demands of current research. Our existing ICP-OES is due to become obsolete and unserviceable in 2022. The aim of this proposal is to replace this essential piece of equipment, to provide continuity of analytical services and deliver optimal, high quality data that would push energy related research efforts to the next level. Detection limits are the most challenging issue with the current ICP-OES. Trace analysis, specifically of Rare Earth Elements (REE), calls for lower detection limits in the sub-ppm range. Recent detection limit studies on the existing equipment suggest there is little confidence in sub-ppm or low-ppm data with optimized sample preparation. Acquisition of an ICP-Mass Spectrometer (MS) addresses current detection limit pitfalls by eliminating optical interferences which skew both elemental identification and quantification. The financial investment into the upgraded technology is greater than replacing the ICP-OES; however, the benefits significantly support the upgrade to meet current energy research needs. This instrument will broadly support multiple departments at the University of Kentucky as well as other local entities. The Analytical Services group at CAER would provide professional staffing to operate and maintain the equipment long-term.
