Liquid extraction surface analysis-mass spectrometry: An advanced and environment-friendly analytical tool in modern analysis.

Abstract

The liquid extraction surface analysis technique is a new high-throughput instrument for ambient mass spectrometry. The benefits of the liquid extraction surface analysis-mass spectrometry approach are the high throughput screening of samples and the absence of sample preparation. liquid extraction surface analysis-mass spectrometry also consumes less solvent for extraction, making it more environmentally friendly and there is no substrate restriction. It utilizes advanced instrumentation like the use of robotic pipettes, nanoelectrospray systems, electronspray ionization chips which makes it highly efficient. In recent years, liquid extraction surface analysis-mass spectrometry has seen widespread use in a variety of analytical fields including drug metabolite analysis, mapping drug distribution in tissues, protein and lipid characterization, etc. In this review, we have summarized the basic working principles of the liquid extraction surface analysis-mass spectrometry approach in detail along with a detailed description of the recently reported applications in the analysis of proteins, lipids, drugs and foods. The investigated analytes along with detection methodologies and significant outcomes of various research reports have been presented with the help of tables. This tool has also been utilized in clinical investigations of biological fluids, fingerprint analysis and authentication of agarwood.
