Title:

Ultra-Low Volume Pulsed Sample Injection for Elemental Analysis with Atomic Emissions Spectroscopy

The AES (Atomic Emissions Spectrophotometer) is a cornerstone technique frequently used for the identification and quantification of elemental composition in environmental monitoring, metallurgy and forensic analysis. The major limitation identified and addressed in this study is that it consumes milliliters of liquid sample solutions under default operation mode. This prevents its use for the study of precious biological, geological, or catalyst samples, which are typically in the volume of microliters. The goal of this research aim to develop a novel operation mode that consumes >10 times fewer sample volumes, to study metal ion partition in the preparation of therapeutic proteins.
