5. KONFERENCE ČESKÉ SPOLEČNOSTI PRO HMOTNOSTNÍ SPEKTROMETRII - Sborník abstraktů

5th Conference of the Czech Society for Mass Spectrometry Summary

Significance of the Topic

Mass spectrometry is a central analytical tool for proteomics, metabolomics, environmental monitoring, pharmaceutical analysis and emerging ambient ionization techniques. The Czech conference brought together experts to share recent advances, new ion sources, imaging methods and application notes across academic and industrial sectors.

Conference Overview and Objectives

This meeting assembled scientists to exchange methods in:

• Development of novel ionization sources including SAW nebulization and desorption nanoelectrospray
• Fundamental ion chemistry and collision induced dissociation studies
• Advances in high-resolution TOF and Orbitrap mass spectrometers with ion mobility
• Applications in organic analysis, biology, food safety, environmental monitoring, clinical metabolomics and imaging
• Complementary workshops by major vendors (Thermo, Bruker, SCIEX, Shimadzu)

Instrumentation and Methodology

Highlights included integration of SAWN with digital microfluidics, LC-QExactive with ion mobility, ambient sources (DESI, DART, nanoDESI, REIMS), hybrid ion traps with helium tagging for spectroscopy, GCxGC-ToF, and high throughput MALDI-MS for drug discovery.

Main Results and Discussion

• New ion sources reduced charging and enabled softer ionization for peptides and small molecules
• Energy-resolved CID and IRPD provided deep insight into peptide fragmentation and metal-ligand structures
• Selected ion flow tube methods (SIFT-MS, PTR-MS, SIFDT-MS) achieved ppbv detection of trace gases and VOCs in breath, atmosphere and food matrices
• Imaging MS revealed lipid and drug distribution in tissues and 3D cell cultures
• Proteomic and glycomic profiling identified disease biomarkers in serum, urine and plant fluids
• ICP-MS with laser desorption captured single nanoparticles and imaging of metals in fungi and biofilms

Practical Benefits

• Improved sensitivity and speed for targeted quantification of pesticides, toxins and pharmaceuticals
• Detailed structural characterization with high confidence for drug metabolites and environmental pollutants
• Imaging capabilities inform on spatial distribution in clinical and food research

Future Trends and Possibilities

Emerging areas include expanding ambient ionization, integrating ion mobility, real-time processes monitoring with microfluidics, big-data metabolomics pipelines and AI-driven spectral interpretation.

Conclusions

The conference demonstrated rapid innovation in ion sources, high-resolution instrumentation, and practical workflows. Strong vendor-academic collaborations and robust method development promise continued growth in MS applications across science and industry.
