Inlet Liner Removal Tool (MANUAL)

Significance of the Topic

In gas chromatography, removing the inlet liner safely and efficiently is crucial for maintaining analytical performance, preventing cross-contamination and minimizing downtime. A dedicated removal tool reduces the risk of glass damage and operator injury.

Study Overview

The document describes the design and use of a removal tool (P/N 227-35032-01) compatible with 5 mm outer diameter liners. It is intended for use at room temperature after the split/splitless inlet has cooled.

Used Instrumentation

• Inlet Liner Removal Tool (Shimadzu P/N 227-35032-01)
• Compatibility: 5 mm outer diameter GC inlet liners
• Recommended operating temperature: ambient

Methodology and Instrumentation

The removal procedure consists of:

1. Hold the injection port and turn the lever counterclockwise to unlock.
2. Slowly lift the injection port straight up to expose the liner, taking care to remove any stuck O-ring with tweezers.
3. Insert the removal tool into the protruding liner section, ensuring the O-ring sealing surface is not damaged.
4. Pull the tool straight up to extract the liner; avoid angled force to prevent breakage.
5. Separate the tool from the hot liner with caution.

Main Results and Discussion

The procedure enhances reproducibility and safety by eliminating manual prying or excessive heat exposure. The dedicated tool streamlines maintenance, reduces liner damage, and lowers the risk of operator burns.

Benefits and Practical Applications

• Improved operator safety and reduced burn hazards
• Minimized risk of glass liner breakage
• Faster, more reliable liner exchange in routine GC maintenance
• Applicable in research, quality control and industrial laboratories

Future Trends and Potential Uses

Further developments may include heat-resistant materials to allow safe handling at higher temperatures, integration with automated inlet modules, and ergonomic refinements for broader compatibility with varying liner designs.

Conclusion

The Shimadzu Inlet Liner Removal Tool offers a simple, effective solution to one of the most common maintenance tasks in gas chromatography, ensuring instrument longevity and laboratory safety.
