Thermo Scientific TRACE GC Ultra Gas Chromatograph (Refurbished)

Overview

The Thermo Scientific TRACE GC Ultra is a high-performance, modular gas chromatograph engineered for precision, reproducibility, and method flexibility in regulated and research-intensive laboratories. Built on Thermo Fisher’s proven TRACE GC platform, the Ultra variant integrates advanced thermal management, ultra-fast column heating, and intelligent pneumatic control to deliver robust separation performance across volatile and semi-volatile organic compounds. Its core measurement principle relies on differential partitioning of analytes between a mobile phase (inert carrier gas—He, H₂, or N₂) and a stationary phase coated inside a fused-silica capillary column, followed by selective detection based on physicochemical properties (e.g., ionization efficiency, electron affinity, flame-induced chemiluminescence). The system supports both routine QC applications and complex method development workflows, particularly where speed, sensitivity, and detector versatility are critical—such as environmental analysis (EPA Method 8270/8081), residual solvent testing (ICH Q3C), petrochemical profiling, and forensic toxicology.

Key Features

• UltraFast Column Heating: Patented direct-resistive column heating enables ramp rates up to 120 °C/min and cooling from 450 °C to 50 °C in under 3.5 minutes—dramatically reducing cycle time without compromising resolution.
• Multi-Mode Inlet Technology: Standard S/SL and programmable temperature vaporizing (PTV) inlets support large-volume injection (LVI) up to 250 µL, enhancing trace-level detectability without derivatization or pre-concentration.
• High-Fidelity Pneumatic Control: Dual-range pressure regulation (0–250 kPa and 0–1000 kPa) ensures optimal carrier gas delivery for both standard capillary analysis and ultra-high-speed GC, with integrated split flow optimization to minimize gas consumption.
• Modular Detector Architecture: Universal detector base accommodates FID, TCD, ECD, NPD, FPD, PID, PDD, and mass spectrometric interfaces—all swappable in under 5 minutes using standard tools; no recalibration required for baseline transfer.
• Automated System Diagnostics: Built-in Automatic Column Evaluation (ACE) and leak-check routines provide real-time column integrity assessment and system integrity verification—critical for 21 CFR Part 11 compliance and audit readiness.

Sample Compatibility & Compliance

The TRACE GC Ultra accepts liquid, gaseous, and headspace samples via autosampler-compatible vials (1.5–2 mL) or gas-tight syringes. It is routinely deployed for EPA 502.2, 524.4, 8021B, 8260D, and ISO 11843-2 compliant analyses. All refurbished units undergo full functional validation per ISO/IEC 17025:2017 technical requirements—including retention time stability (RSD < 0.05%), peak area repeatability (RSD < 1.2% for n-decane at 100 ng), and detector linearity verification (≥ 4 orders of magnitude for ECD/FID). Each instrument ships with a Certificate of Reconditioning, traceable calibration records, and a complete set of consumables (septa, liners, ferrules, O-rings). Optional IQ/OQ documentation packages are available for GMP/GLP environments.

Software & Data Management

The system operates natively with Thermo’s ChromQuest 5.x or Chromeleon 7.3 CDS (optional upgrade), supporting LAN-based remote monitoring, scheduled maintenance alerts, and electronic signature-enabled method locking. Audit trails record all parameter changes, sequence edits, and report generations—fully compliant with FDA 21 CFR Part 11 requirements when configured with role-based user accounts and secure password policies. Raw data files (.raw) are stored in vendor-neutral formats compatible with third-party processing tools (e.g., OpenChrom, Simplicity). Instrument control, method deployment, and report generation can be executed via desktop client or web browser interface, enabling seamless integration into centralized LIMS environments.

Applications

• Environmental: Pesticide residue screening (EPA 8081B), chlorinated hydrocarbons (EPA 8021B), BTEX and PAH quantification in soil/water extracts.
• Pharmaceutical: Residual solvent analysis per ICH Q3C guidelines; genotoxic impurity profiling using PDD or ECD.
• Food & Flavor: Volatile organic compound (VOC) fingerprinting in essential oils, fermentation off-gases, and packaging migration studies.
• Petrochemical: Hydrocarbon group-type analysis (HTA) via dual-FID/TCD configuration; sulfur speciation using FPD with dual PMT detection.
• Forensics: Toxicological screening of drugs of abuse (e.g., amphetamines, benzodiazepines) using NPD/ECD selectivity and confirmatory MS coupling.

FAQ

Is this unit fully refurbished and tested prior to shipment?
Yes. Every TRACE GC Ultra undergoes comprehensive electrical, thermal, and pneumatic validation at SpectraLab’s ISO 17025-accredited facility, including detector sensitivity verification, inlet leak testing, and column oven temperature uniformity mapping.
What documentation accompanies the instrument?
You receive a Certificate of Reconditioning, full calibration logs, software license keys (where applicable), and a detailed hardware inventory list. Optional 21 CFR Part 11-compliant IQ/OQ documentation is available upon request.
Can I integrate this GC with my existing LIMS or ELN?
Yes. The instrument supports ASTM E1384-compliant data export and offers OPC UA connectivity for enterprise-level integration. ChromQuest and Chromeleon both support direct LIMS interfacing via ASCII or XML export templates.
Are original Thermo Fisher service contracts transferable?
No—refurbished units are covered under SpectraLab’s 6-month parts-and-labor warranty. Extended service plans (1–3 years) with priority response and preventive maintenance visits are available separately.
Does the system include consumables and spare parts?
Yes. Each unit ships with a starter kit containing 20 septa, 10 glass liners, 10 graphite ferrules, 2 O-rings per inlet/detector, and one deactivation kit for inlet maintenance.
