GC/GC-MS Glass Insert/Liner Selection Guide
Guides | 2024 | ShimadzuInstrumentation
The choice of glass inserts or liners in gas chromatography (GC) and GC–mass spectrometry (GC–MS) is critical to achieving reliable, high-quality analytical results. Proper insert selection improves vaporization efficiency, reduces sample dispersion, and prevents contamination of the injection unit, directly impacting sensitivity, resolution, and repeatability.
This guide reviews criteria for selecting glass inserts for diverse Shimadzu GC platforms and headspace samplers. It explains key insert features, aligns them with common injection methods, and offers selection tables by instrument model and application to streamline decision making.
Insert selection is based on:
Clear selection tables match insert part numbers to GC models and injection modes. Recommendations include narrow-bore inserts for SPME/SPME-Arrow, water-optimized inserts for aqueous solvent analysis, and dual-purpose split/splitless liners. Guidelines address wool filling protocols, heat-resistance limits (350–450 °C), and trade-offs between vaporization efficiency and potential sample adsorption.
Advances may include customized surface coatings to further minimize adsorption, integrated sensor feedback on insert condition, and expanding insert designs for micro- and nano-flow GC. Emerging sample introduction techniques (e.g., thermal desorption, pyrolysis) will benefit from tailored liner solutions.
Proper glass insert selection is essential for maximizing GC/GC–MS analytical performance. This guide provides a structured approach to choose inserts by instrument, method, and application, enhancing data quality and operational efficiency.

Summary
Importance of Topic
The choice of glass inserts or liners in gas chromatography (GC) and GC–mass spectrometry (GC–MS) is critical to achieving reliable, high-quality analytical results. Proper insert selection improves vaporization efficiency, reduces sample dispersion, and prevents contamination of the injection unit, directly impacting sensitivity, resolution, and repeatability.
Objectives and Overview
This guide reviews criteria for selecting glass inserts for diverse Shimadzu GC platforms and headspace samplers. It explains key insert features, aligns them with common injection methods, and offers selection tables by instrument model and application to streamline decision making.
Instrumentation
- Shimadzu GC models: Nexis GC-2030/GC-2050, GC-2010/2014/2025 series
- Injection units: Split/Splitless (SPL), Direct full volume (WBI/OCI), Programmable temperature vaporization (PTV), Packed column injection (SINJ/DINJ)
- Headspace samplers: HS-10 and HS-20 (no insert required for HS-20)
Methodology and Key Considerations
Insert selection is based on:
- Injection method and unit compatibility
- Wool presence, material (glass or quartz), position and amount for optimal vaporization and mixing
- Insert shape: tapered tips focus vapors, offset-protrusions secure wool
- Inner diameter and volume: wider diameters suit high-volume samples, narrow diameters improve peak shape for volatile analytes
- Surface treatment: silanization or inactivation reduces adsorption and thermal degradation of sensitive compounds
Main Findings and Discussion
Clear selection tables match insert part numbers to GC models and injection modes. Recommendations include narrow-bore inserts for SPME/SPME-Arrow, water-optimized inserts for aqueous solvent analysis, and dual-purpose split/splitless liners. Guidelines address wool filling protocols, heat-resistance limits (350–450 °C), and trade-offs between vaporization efficiency and potential sample adsorption.
Benefits and Practical Applications
- Enhanced chromatographic performance and reproducibility
- Reduced maintenance and column contamination
- Versatility across trace and high-boiling analyte workflows
- Simplified selection process for routine QA/QC and research labs
Future Trends and Potential Applications
Advances may include customized surface coatings to further minimize adsorption, integrated sensor feedback on insert condition, and expanding insert designs for micro- and nano-flow GC. Emerging sample introduction techniques (e.g., thermal desorption, pyrolysis) will benefit from tailored liner solutions.
Conclusion
Proper glass insert selection is essential for maximizing GC/GC–MS analytical performance. This guide provides a structured approach to choose inserts by instrument, method, and application, enhancing data quality and operational efficiency.
