List of Posters ESAS-CSSC 2022

Importance of the Topic

Analytical chemistry poster sessions bring together diverse research efforts to address critical challenges in environmental monitoring, biomedical analysis, materials characterization and industrial quality control. These events foster rapid knowledge exchange, highlight methodological innovations and promote collaborative problem solving across academia and industry.

Objectives and Overview of the Session

The Monday and Tuesday poster sessions at the Faculty of Social Studies feature forty-five presentations each day, covering cutting-edge spectroscopic, mass spectrometric and separation techniques. Key objectives include:

• Showcasing new developments in laser-based methods (LIBS, LA-ICP-MS, Raman mapping)
• Advancing sample preparation and green extraction strategies
• Demonstrating hyphenated approaches for speciation and multielement analysis
• Exploring novel instrumentation and data processing workflows

Methodological Approaches

Presentations span a broad array of analytical methodologies:

• Atomic spectrometry: ETAAS, ICP-MS/MS, ICP-OES, AFS and TXRF for trace element detection
• Vibrational spectroscopy: FT-IR, NIR, Raman, SERS and nanoscale IR for molecular characterization
• Laser-induced techniques: LIBS for in situ elemental profiling and laser ablation synthesis
• Mass spectrometry: FT-ICR MS with CID, HPLC-ICP-DRC-MS speciation, time-of-flight and ion funnel simulations
• Microscopy and diffraction: SEM, XRD and mu-XRF for structural and depth-resolved elemental analysis
• Complementary methods: Mössbauer spectroscopy, positron annihilation and chemiluminescent flow injection analysis

Main Findings and Discussion

Several trends emerge from the posters:

• Enhanced sensitivity and selectivity via nanostructured substrates, upconversion labels and spray-deposited standards
• Integration of green chemistry principles in microextraction and vapor generation workflows
• Improved quantification through matrix-matched calibration, sequential extraction and isotopic labeling
• Expansion of hyphenated platforms enabling simultaneous elemental and molecular speciation
• Application of advanced data analysis, from acoustic signal processing in LIBS to feature engineering for classification

Benefits and Practical Applications

These advances offer substantial gains for routine and research laboratories:

• Faster, non-destructive analyses of cultural heritage objects, foodstuffs and biological tissues
• Robust monitoring of pollutants and bioaccumulation in environmental matrices
• Precise control of material properties in polymers, alloys and catalysts
• Enhanced screening capabilities in pharmaceutical and clinical contexts

Future Trends and Applications

Looking ahead, poster topics point toward:

• Miniaturized, field-deployable instrumentation with real-time data feedback
• Advanced chemometric and machine learning tools for multivariate data interpretation
• Integration of multiple detection modalities into unified platforms
• Greater emphasis on sustainable, solvent-free sample preparation methods
• Expansion of in situ and imaging techniques at the micro- and nanoscale

Conclusion

The poster sessions illustrate a vibrant landscape of analytical chemistry innovation. By uniting methodological advances with practical applications, participants are driving progress in trace analysis, materials science and bio-analysis. Continued collaboration and interdisciplinary approaches are essential to address emerging challenges in environmental, industrial and biomedical fields.
