VICI Jour - Chromatography Fluid/Gas Transfer

Importance of the topic

The efficient and reliable transfer of fluids and gases is fundamental to chromatographic techniques such as GC, HPLC, UHPLC, micro-LC, and nano-LC. High-performance tubing, fittings, filters, and accessories ensure minimal dead volume, chemical compatibility, and high pressure tolerance. Quality fluid connections directly impact resolution, reproducibility, and the lifetime of analytical columns and instruments.

Objectives and overview

This catalog summarizes the latest product introductions and enhancements by VICI Jour, a leading supplier of fluid transfer components. It presents new and expanded lines of tubing materials, high-pressure polymeric and stainless-steel fittings, Nanovolume® low-dead-volume connectors, in-line and precolumn filters, safety products, sample loops, and general accessories.

Methodology and instrumentation

VICI Jour employs precision extrusion, injection molding, and machining to produce fluidic components. Key materials and manufacturing features include:

• PEEK, PEEK-HT™, PVDF, PTFE, FEP, ETFE, PFA, and fused-silica capillaries, tailored for pressures up to 1000 bar and temperatures to 350 °C
• Type 316 stainless steel tubing and fittings, cold-drawn or welded, for pressures up to 1375 bar
• Electrolytic cutting and steam cleaning for burr-free, ultra-clean pre-cut tubing
• One-piece and multicomponent Fingertight® fittings in polymeric and metal variants
• Filters with 0.2–20 µm porosity, including inline, precolumn, and mobile-phase spargers

Main results and discussion

Major product highlights include:

• New untreated fused-silica capillaries (360 µm OD) for micro/nano LC
• Expanded PEEK tubing sizes and color-coded striped or dual-layer options for rapid line identification
• PEEK-HT™ one-piece fittings rated to 500 bar fingertight and 1000 bar with tools
• Nanovolume® 100–150 µm OD ferrule-free fittings for ultra-low transfer volumes
• Stainless steel UHPLC tubing with 75 µm ID and premium seamless construction
• High- and low-pressure polymeric adapters, safety exhaust filters with breakthrough detectors, and versatile cap kits for gradient HPLC

Benefits and practical applications of the method

The new components deliver:

• Enhanced pressure and temperature resistance for demanding UHPLC and SFC systems
• Reduced dead volume and sample dispersion, critical for micro- and nano-flow rates
• Improved chemical inertness and biocompatibility for proteomics, pharmaceuticals, and bioanalysis
• Rapid solvent line identification via color-coded tubing and fingertight adapters
• Easier installation and maintenance with pre-cut, steam-cleaned tubing and one-piece fittings

Future trends and potential applications

Advances in miniaturized and high-throughput separations will drive further demand for:

• Sub-50 µm capillary and microfluidic tubing for single-cell and metabolomics applications
• Hybrid polymer-metal composite fittings combining high-pressure performance with chemical inertness
• Integrated micro-valve and fluidic manifold kits for automated sample handling
• Smart tubing and fittings with embedded sensors for in-line pressure and leak monitoring

Conclusion

VICI Jour’s latest catalog demonstrates significant innovations in fluid transfer technology, offering comprehensive solutions for HPLC, UHPLC, micro/nano LC, GC, and sample handling. By combining advanced materials, precision manufacturing, and user-friendly design, these products enhance chromatographic performance, reduce downtime, and support evolving analytical challenges.
