Agilent GC AND GC/MS - Catalog Consumables and Spare Parts

Importance of the Topic

Reliable analysis of trace and labile compounds in gas chromatography (GC) and GC/mass spectrometry (GC/MS) critically depends on maintaining an inert flow path from injection to detection. Active sites on metal and glass surfaces, column bleed, and gas impurities can degrade sensitive analytes, raise detection limits, and undermine reproducibility. Innovations in deactivation chemistries, inert hardware design, and rigorous quality testing help laboratories achieve lower detection limits, higher accuracy, and consistent performance in routine and challenging applications.

Objectives and Overview of the Article

This catalog overview aims to present Agilent’s complete portfolio of GC and GC/MS columns, inlets, supplies, and service solutions optimized for inert performance. It highlights:

• Innovations in Ultra Inert Flow Path components for trace‐level analysis of active compounds.
• Precision-manufactured columns and consumables for improved reproducibility.
• Service, support, and compliance offerings for instrument reliability and regulatory readiness.

Methodology and Instrumentation Used

Agilent’s inert flow path solutions are validated through controlled chromatographic QC tests on each component lot. Key instrumentation and supplies include:

• GC and GC/MS Systems: Models 7820A, 7890B GC; 5977, 5975T, 7000C, 7010, 7200 Q-TOF, and other MSD analysers.
• Ultra Inert Flow Path Components: Inlet liners, gold-plated seals, J&W Ultra Inert capillary columns, UltiMetal Plus ferrules, and Purged Effluent Splitters.
• Gas Management: Gas Clean Filter System to remove oxygen, moisture, and hydrocarbons at≤1 ppb levels.
• Column Connection Hardware: Self-Tightening column nuts, precision ferrules (graphite/polyimide and flexible metal), press-fit and Ultimate Union connectors.
• Sample Introduction: Certified septa, crimp and screw vial closures, 7693A ALS, 7697A and 7820/7890 headspace samplers, Teledyne Tekmar and Markes Purge & Trap and Thermal Desorption accessories.
• Service and Compliance: Agilent Advantage Service Plans, Remote Advisor connectivity, and Enterprise Edition Compliance.

Main Results and Discussion

Extensive QC testing confirms that Agilent’s Ultra Inert components deliver:

• Reproducible chromatographic response across multiple lots, maintaining low bleed and background.
• Improved peak shape and sensitivity for active analytes such as acids, bases, pesticides, and sulfur compounds.
• Extended column and inlet lifetime, reducing downtime and maintenance costs.
• Lower detection limits down to parts-per-trillion for environmental, forensics, food safety, and pharmaceutical analyses.

Adoption of new Self-Tightening nuts and Touchless packaging further streamlines workflow, minimizing installation errors and sample cross-contamination.

Benefits and Practical Applications of the Method

Agilent’s inert flow path and precision consumables enable laboratories to:

• Confidently quantify trace-level and labile compounds without active site losses.
• Increase productivity by reducing maintenance frequency and consumable changeover time.
• Ensure method transferability and reproducibility across GCs, GC/MSDs, and GC/MS/MS platforms.
• Support a broad range of applications: environmental (water, soil), food and flavor, pharmaceuticals, forensics, energy, and materials science.

Future Trends and Possibilities of Use

Continued advances are anticipated in:

• Next-generation deactivation chemistries for ultra-high temperature PTV and pyrolysis inlets.
• Micro- flow and low-dead-volume components for micro-GC and portable analysers.
• AI-enabled diagnostics and predictive maintenance via enhanced Remote Advisor data analytics.
• Integrated multi-dimensional GC, PTV, and thermal desorption modules for comprehensive volatile profiling.
