VICI Jour - Chromatography Fluid/Gas Transfer

Significance of Fluid and Gas Transfer Accessories in Chromatography

Precise fluid and gas transfer components such as tubing, fittings, filters, and safety devices are crucial for reliable and reproducible chromatographic analyses. High-pressure, low-dead-volume connections minimize band broadening and sample loss, while robust materials and safety filters protect both equipment and laboratory personnel.

Overview of the VICI Jour Product Line

The 20th edition catalog presents a comprehensive range of VICI Jour accessories, including:

• Chromatography-grade tubing: PEEK, ETFE, PFA, FEP, PTFE, fused silica, and stainless steel in various diameters and lengths.
• High-pressure fittings: One-piece PEEK, PEEK-HT™, PVDF, metal compression, and Nanovolume® connectors for UHPLC down to 360 µm OD.
• Low-pressure fittings: 1/4-28 fingertight, flanged and flangeless connectors, unions and rotary valves for low-pressure LC and FIA.
• Filters: In-line and pre-column filters in PEEK, stainless steel, and polymeric formats with multiple porosities to protect columns and detectors.
• Safety products: Caps, exhaust filters with breakthrough detectors, mobile phase handling systems, and coiled solvent tubing for safer solvent management.

Manufacturing and Quality Control

All products are manufactured to tight tolerances under ISO 9001 standards, ensuring chemical inertness, biocompatibility, and reliable high-pressure performance. Proprietary processes yield uniform frit porosity and tubing dimensions, while steam or hexane cleaning guarantees low contamination levels.

Key Benefits and Practical Applications

• Reduced dead volume and improved chromatographic peak shapes.
• Enhanced mobile phase stability through degassing and filtration.
• Extended column lifetime via in-line and guard filters.
• Safe solvent handling with air inlet/outlet valves, exhaust filters, and sealed caps.
• Flexible system design using coiled tubing and modular fittings for easy reconfiguration.

Future Trends and Possibilities for Use

Continued miniaturization in micro- and nano-LC will drive demand for ultra-low-volume Nanovolume® components. Growing biopharmaceutical analysis requires metal-free and biocompatible materials. Automation, flexible solvent storage, and advanced safety caps will support high-throughput workflows. Emerging applications in metabolomics and single-cell analysis will further emphasize low dispersion and inert flow paths.

Conclusion

The VICI Jour catalog exemplifies a complete, high-quality accessory portfolio for modern chromatography, addressing challenges from ultra-high-pressure nano-LC to routine analytical workflows. Its focus on reproducibility, safety, and system flexibility makes it an essential resource for analytical, QA/QC, and research laboratories.
