List of Posters ESAS-CSSC 2022

Importance of the Topic

The combined Monday and Tuesday poster sessions at the Faculty of Social Studies auditorium provide a concentrated showcase of cutting-edge analytical chemistry methods spanning spectroscopy, mass spectrometry, separation science and novel sampling approaches. Bringing together interdisciplinary studies from protein structure to environmental toxicology, this forum highlights the critical role of advanced instrumentation and method development in addressing real-world challenges in bioanalysis, materials research, environmental monitoring and industrial quality control.

Objectives and Session Overview

The primary goals of the sessions are to:

• Present newly developed analytical methodologies and instrument configurations.
• Demonstrate applications in areas such as nanoparticle characterization, trace element speciation, polymer and membrane analysis, and biological system investigations.
• Foster cross-disciplinary dialogue and collaboration among researchers, instrument developers and end users.

In total, over forty presentations cover topics including laser-based spectroscopy (LIBS, Raman, IR/NIR), hyphenated mass spectrometry (ICP-MS, LA-ICP-MS, MS/MS), atomic fluorescence, X-ray based techniques (XRF, TXRF, XRD), sequential extraction protocols and microextraction procedures.

Applied Methodologies and Techniques

Key analytical platforms featured:

• Laser-induced breakdown spectroscopy and ablation for rapid multielement analysis and plume diagnostics.
• Inductively coupled plasma methods (ICP-MS, ICP-OES, ICP-DRC-MS) for trace metal and rare earth determination in environmental and geological samples.
• Vibrational spectroscopies (FT-IR, Raman, SERS) for molecular structure, cell permeation studies and surface chemistry investigations.
• Atomic absorption and fluorescence spectrometry (ETAAS, AAS) enhanced by novel vapor generation and trapping approaches.
• Advanced separation hyphenation (HPLC/ICP, sequential injection analysis) for speciation of organic and inorganic analytes.

Key Themes and Highlights

Several recurring themes emerge:

• Green and miniaturized sample preparation strategies, including deep eutectic solvents and microextraction.
• Non-destructive depth-resolved elemental profiling using micro-XRF and tabletop CμXRF instruments.
• Nanoparticle synthesis monitoring and luminescence enhancement techniques for biomedical tagging and environmental tracing.
• Application of chemometric and feature-engineering approaches to improve classification and quantification in complex matrices.
• Innovations in cell-mimetic and membrane studies employing vibrational spectroscopy and positron annihilation.

Benefits and Practical Applications

These developments translate into:

• Enhanced sensitivity and lower detection limits for toxic elements in food, water and biological tissues.
• Faster throughput and real-time capabilities for process monitoring in materials and pharmaceutical industries.
• Improved specificity in speciation analysis critical for risk assessment of environmental contaminants.
• New tools for quality control in glass, polymer and composite manufacturing.

Future Trends and Potential Uses

Emerging directions include integration of artificial intelligence for automated spectral interpretation, lab-on-chip miniaturization of ICP and AAS systems, remote and in-situ monitoring with portable LIBS and Raman devices, and expanded use of green chemistry principles in sample treatment.

Conclusion

The sessions collectively underscore the dynamic progress in analytical chemistry instrument design and methodology. By converging diverse spectroscopic and separation techniques, researchers are better equipped to tackle pressing challenges in health, environment and industrial analytics, paving the way for more sustainable, accurate and high-throughput solutions.
