Meet The World’s First Multi-Mode FID In Nexis GC-2060

Summary: Multi-Mode FID (FID-U 2.0) in Nexis GC-2060

Significance of the topic

Flame ionisation detection (FID) is a cornerstone detector in gas chromatography for hydrocarbon analysis due to its wide dynamic range, robustness, and linear response to carbon. Advances that reduce operational cost, laboratory footprint and maintenance while extending analyte coverage (e.g., CO/CO2 detection and universal carbon response) have direct impact on routine QA/QC, research laboratories and industrial analytics. The FID-U (2.0) introduced in the Nexis GC-2060 addresses these priorities by combining higher sensitivity, expanded makeup-gas flexibility (including cylinder-free options), and compatibility with catalytic microreactors to broaden detectable species and simplify quantitation workflows.

Objectives and overview of the product/communication

The document presents the design features, operational modes and practical benefits of Shimadzu's FID-U (2.0) implemented in the Nexis GC-2060. Key aims are to: reduce gas-supply complexity (including enabling cylinder-free operation), improve minimum detectable quantity (MDQ), increase robustness and user-serviceability, and allow seamless integration of catalytic microreactors (Jetanizer and Polyarc) to expand analyte coverage and simplify calibration strategies.

Methodology and used instrumentation

The device-level innovations and operational configurations are described rather than an experimental protocol. Main instrumentation and components referenced in the material include:

• Nexis GC-2060 gas chromatograph equipped with FID-U (2.0) detector.
• FID-U (2.0): multi-mode flame ionisation detector with integral metal nozzle and redesigned collector for easier disassembly and cleaning.
• Shimadzu Jetanizer microreactor: converts CO and CO2 to CH4 for FID detection.
• Polyarc microreactor: converts hydrocarbons, CO and CO2 to CH4 delivering near-universal carbon response (single-calibration quantitation).
• Gas supply options: He or N2 as traditional makeup gases; Air or O2 makeup gas options enabling Hy/Air and Hy/Ox modes which can reduce or remove the need for cylinder gases.
• Gas generators and accessories: H2 generators (e.g., PEAK Intura H2|O2), air compressors with AGE-1000 dryer, and silica gel moisture traps recommended for cylinder-free operation.

Main results and discussion

Performance and operational highlights reported:

• Sensitivity: The FID-U (2.0) achieves an MDQ of 1.0 pg C/s in the standard 3-gas configuration — presented as an improvement over the previous model (1.2 pg C/s).
• Nozzle and robustness: The integral metal nozzle replaces mixed metal/quartz designs, improving mechanical robustness and enabling solvent/ultrasonic cleaning of nozzle and collector.
• Makeup gas flexibility: New supported modes include Hy/Air and Hy/Ox for cylinder-free operation when paired with suitable generators or compressed-dry air, with reported MDQs dependent on mode: 3-gas (1.0 pg C/s), Hy/Air (1.5 pg C/s), Hy/Ox (3.0 pg C/s). Users are cautioned that MDQ is influenced by local utility conditions and that moisture removal (silica gel) is recommended.
• Microreactor integration: Jetanizer and Polyarc microreactors can be fitted without additional bench footprint (no extra space required) to expand the detectable compound set. Jetanizer enables CO/CO2 detection by conversion to CH4; Polyarc provides universal carbon response, enabling multi-class quantitation from a single calibration curve.
• Maintenance and usability: Redesigned collector and nozzle allow straightforward user cleaning. A built-in Maintenance Help feature supplies stepwise instructions with photos and videos to guide routine service actions, intended to reduce downtime and reliance on specialized service calls for typical cleaning tasks (mode switching between Hy/Ox and others requires Shimadzu service intervention).

Benefits and practical applications

The combination of features achieves several practical advantages for laboratories:

• Lower operating cost: Reduced helium consumption and potential elimination of makeup-gas cylinders when using air/O2 and appropriate generators or compressed air systems.
• Reduced bench footprint: Integration of microreactors without extra space and elimination of additional gas cylinders simplifies lab layout.
• Expanded analyte scope: Ability to detect CO and CO2 plus universal carbon response via Polyarc widens applicability to environmental, petrochemical and process-monitoring analyses where non-hydrocarbon carbon species and cross-class quantitation are required.
• Simplified workflows: Single-calibration quantitation (Polyarc) and improved detector response reduce method complexity and calibration workload.
• Improved uptime and lower maintenance burden: Metal nozzle/collector and guided maintenance materials facilitate faster, user-performed servicing.

Future trends and possibilities for use

Adoption of multi-mode, low-maintenance detectors like FID-U (2.0) points to several broader trends and opportunities:

• Cylinder-free GC labs: Wider uptake of air/O2 makeup modes and integrated gas generators could significantly reduce dependence on compressed gas cylinders, with sustainability and cost benefits.
• Integrated catalytic reactors: Increasingly routine use of microreactors (Jetanizer, Polyarc or future catalytic modules) to expand detector capability and enable universal-response quantitation across compound classes.
• Software and automation: Tighter integration of detector modes, maintenance diagnostics, and guided workflows within instrument software to minimize operator variability and speed troubleshooting.
• Method standardization: Development of validated methods for Hy/Air and Hy/Ox modes and for Polyarc single-calibration approaches to broaden regulatory acceptance.
• Field and process analytics: Robust metal-nozzle designs and cylinder-free configurations could facilitate deployment in process or near-field environments where gas logistics are constrained.

Conclusion

The FID-U (2.0) implemented in the Nexis GC-2060 represents a pragmatic evolution of flame ionisation detection by combining improved sensitivity, expanded makeup-gas flexibility (including practical cylinder-free modes), and simplified maintenance with plug-in microreactor capabilities. These advances reduce operational cost and complexity while broadening analyte coverage and simplifying quantitation workflows, making the detector attractive for routine QC, R&D and industrial applications where uptime, cost-efficiency and broader detection are priorities. Users should consider local utility quality, moisture control and manufacturer guidance for safe and optimal configuration.
