GC Column Unions and Splitters

Unions and Splitters for GC Applications

Reliable, Tool-Free Connections for High-Performance Chromatography

Fused Quartz Y-Splitters

Designed for versatile sample distribution in gas chromatography, Zebron™ Fused Quartz Y-Splitters provide a simple, reliable way to split flow:

• Split samples between two columns for confirmational analysis from a single injection

• Direct column effluent to dual detectors for enhanced data collection

• Tool-free, leak-tight sealing even at elevated temperatures and pressures

• Laser-cut, polished ends protect column integrity during insertion

• Ideal for use in high-temperature GC environments

Application: Fused Quartz Y-Splitters for GC

Fused Quartz Press-Fit Unions

Zebron™ Fused Quartz Press-Fit Unions are designed for seamless connections between capillary columns and other components:

• Connects guard columns, analytical columns, or transfer lines (e.g., to mass spectrometers)

• Maintains a leak-free seal without tools or fittings

• Withstands high-temperature and high-pressure GC conditions

• Laser-cut ends prevent damage to column ends during connection

Application: Fused Quartz Press-Fit Unions for GC

Polyimide Resin

Ensure permanent, vibration-resistant connections between fused quartz unions/splitters and capillary tubing:

• Secures fittings against dislodgement caused by vibration or shock

• Available in:

  • Standard formulation: rated to 350 °C

  • High-temperature formulation: rated to 400 °C

Application: Polyimide Resin for GC Fittings

Capillary Mini-Unions

High-precision, low dead volume connections for capillary GC columns of varying internal diameters:

• Glass-lined internal bore ensures inertness and minimal peak dispersion

• Includes: 1 mini-union, 2 nuts, and 5 ferrules

• Compatible ferrule options:

  • Vespel/Graphite (85/15%) – rated to 350 °C

  • SilTite® – rated to 450 °C
