Plasmion SICRIT® GC/SPME Module - Installation and Operations Manual

Importance of the Topic

Gas chromatography combined with solid-phase microextraction (SPME) allows fast, solvent-free sampling of trace volatiles. Integrating SICRIT® cold plasma ionization offers soft ionization and direct coupling to mass spectrometers, enhancing sensitivity and enabling real-time analysis in research and QA/QC laboratories.

Objectives and Overview of the Manual

This manual guides users through installation, setup and operation of the SICRIT® GC/SPME Module (version 0.3). It details mounting on SICRIT® MS interfaces, orientation options for SPME-MS and GC-MS modes, gas connections and control of heating and ionization parameters.

Methodology and Instrumentation

• SICRIT® cold plasma ionization technology in flow-through mode
• Modular heating chamber with stainless steel liner and Swagelok connection
• Mounting rails and lock-lever system for vertical SPME desorption and horizontal GC coupling
• Carrier gas supply, optional humidifier, and PAL® autosampler integration
• Thermal control via SICRIT® SC-30 Control Unit or GC auxiliary heaters

Used Instrumentation

• SICRIT® GC/SPME Module (110×50×50 mm, up to 320 °C)
• SICRIT® Control Unit SC-30
• SICRIT® Interface TX2 (or TX3) for MS integration
• SICRIT® Ion source SC-30X cold plasma ionizer
• PAL® Autosampler for SPME fibers
• Heated GC transferline and Thermo Fisher GC-MS systems

Main Results and Discussion

The module supports direct SPME-MS by vertical insertion of fibers into the heated chamber, achieving rapid desorption and transfer into the ion source. In GC-MS mode, the horizontal orientation and heated transferline enable seamless column output into the SICRIT® ion source. Fast temperature ramps (rt→250 °C) and stable operation are achieved within 10 minutes. Maintenance is limited to liner replacement and surface cleaning.

Benefits and Practical Applications

• Solvent-free, rapid analysis of volatiles and semi-volatiles
• Enhanced sensitivity via soft plasma ionization
• Flexible mounting and orientation for diverse workflows
• Compatibility with standard PAL® autosamplers and GC systems
• Minimal maintenance and straightforward troubleshooting

Future Trends and Potential Applications

Integration with automated workflows and data analytics platforms may streamline high-throughput screening. Expansion to other chromatographic techniques (HPLC, micro-GC), miniaturization of transferlines and real-time field deployable modules will broaden application in environmental monitoring, food safety and clinical diagnostics.

Conclusion

The SICRIT® GC/SPME Module offers a robust, versatile solution for coupling SPME and GC with SICRIT® cold plasma ionization. Its modular design, rapid thermal control and compatibility with existing MS platforms make it a valuable tool for trace analysis in research, QA/QC and industrial settings.
