Importance of the Topic
The Monday and Tuesday poster sessions at the analytical chemistry conference showcase a broad spectrum of cutting-edge techniques and applications. By bringing together early-career researchers and seasoned experts, these sessions foster rapid knowledge exchange in areas such as spectroscopy, mass spectrometry, separation science, and sample preparation. The variety of methods on display highlights the ongoing drive toward higher sensitivity, faster analysis, and more sustainable protocols in both fundamental research and applied laboratories.
Objectives and Overview
The main goals of the poster sessions are:
- To present novel analytical approaches across 89 individual contributions.
- To compare instrumentation performance for real-world samples (e.g., algae, glass, biological matrices).
- To develop and validate greener, more efficient sample-preparation and detection workflows.
- To foster interdisciplinary collaboration among chemical, biological, and material scientists.
Methodology and Instrumentation
Techniques represented include:
- Vibrational spectroscopy: IR, NIR, Raman, Surface-enhanced Raman (SERS), 3D mapping.
- Atomic and mass spectrometry: LIBS, ICP-MS (including LA-ICP-MS, ICP-DRC-MS, ICP-MS/MS), ICP-OES, ETAAS, TXRF, XRF.
- Laser-based methods: laser ablation sampling, LIBS for non-metals and trace elements, laser-induced emission.
- Separation hyphenation: HPLC/ICP-MS, HG-ICP-MS.
- Microscopy and imaging: SEM, XRD, X-ray diffraction, positron annihilation spectroscopy.
- Specialized atomizers and traps: dielectric barrier discharge devices for vapor generation, DBD atomizers for in-situ trapping.
Key Findings and Discussion
While individual results vary, common themes emerge:
