PerkinElmer AutoSystem GC with Autosampler and Thermal Conductivity Detector

Overview

The PerkinElmer AutoSystem GC with Autosampler and Thermal Conductivity Detector (TCD) is a robust, benchtop gas chromatography system engineered for high reproducibility in permanent gas and light hydrocarbon analysis. Based on classical packed- or capillary-column separation principles, this instrument employs thermal conductivity detection—a universal, non-destructive, concentration-sensitive technique ideal for quantitative analysis of H₂, O₂, N₂, CH₄, CO, CO₂, and C₂–C₄ hydrocarbons. Originally manufactured in Canada and widely deployed in petrochemical, environmental monitoring, and industrial QA/QC laboratories, the AutoSystem platform features a precision temperature-controlled oven (±0.1 °C stability), programmable ramp rates (0.1–40 °C/min), and dual independent detector channels supporting simultaneous column configurations. Its mechanical architecture emphasizes long-term thermal stability and pressure integrity—critical for retention time repeatability across extended operational cycles.

Key Features

• Thermal Conductivity Detector (TCD) with dual filament configuration, optimized for low-noise baseline performance and linear response over five orders of magnitude (0.1–100% v/v)
• Integrated autosampler capable of handling up to 100 vials with programmable injection volume (0.1–100 µL), syringe wash cycles, and multi-segment sequence control
• Temperature-programmable column oven with forced-air convection, operating range from ambient +10 °C to 450 °C, and precise isothermal/gradient control
• Electronic pneumatic control (EPC) module for carrier gas (He, H₂, or N₂), make-up gas, and detector flow regulation—ensuring consistent retention and peak shape
• Refurbishment includes full optical and electrical calibration, leak testing per ASTM E1803, replacement of critical consumables (septa, liner, ferrules, detector filaments), and firmware validation against original PerkinElmer specifications

Sample Compatibility & Compliance

This system supports both packed and fused-silica capillary columns (0.1–0.53 mm ID), accommodating standard analytical methods for refinery gas (ASTM D1945), natural gas composition (ISO 6974-2), and residual solvent screening (USP ). All refurbished units undergo method verification using certified reference standards (e.g., Air Liquide Gas Mixtures, NIST SRM 1620). The hardware architecture complies with GLP/GMP documentation requirements, including audit-ready log files for instrument status, method parameters, and run history. While not FDA 21 CFR Part 11–certified out-of-the-box, the system supports integration with validated LIMS environments via RS-232 or Ethernet interfaces.

Software & Data Management

The AutoSystem operates with TurboChrome™ data acquisition software (v5.x), providing real-time chromatogram display, peak integration with customizable baselines and thresholds, calibration curve generation (linear, quadratic, or polynomial), and report export in PDF, CSV, or XML formats. Raw data files (.raw) are stored with embedded metadata—including operator ID, method name, injection time, and detector voltage traces—enabling traceability under ISO/IEC 17025 and internal quality audits. Optional upgrades include TurboChrome Compliance Pack for electronic signature support and audit trail logging.

Applications

• Quantitative analysis of permanent gases in syngas, biogas, and fuel cell feed streams
• Hydrocarbon speciation in refinery off-gas and liquefied petroleum gas (LPG)
• Residual oxygen and moisture content measurement in high-purity industrial gases
• Educational training platforms for fundamental GC theory, detector physics, and method development
• Backup or secondary GC systems in regulated laboratories requiring redundancy without capital expenditure on new instrumentation

FAQ

Is this instrument suitable for regulatory submissions under USP or EP monographs?

Yes—when operated with validated methods and documented calibration records, this system meets technical requirements for USP , EP 2.2.27, and ISO 17025-compliant testing.
What consumables are included with the refurbishment?

Each unit ships with one set of inlet septa, gold-plated ferrules, deactivated glass liners, and a calibrated TCD filament kit.
Can the autosampler be upgraded to support headspace or pyrolysis modules?

The AutoSystem chassis supports third-party headspace samplers (e.g., CDS 7000 series) via standard 1/16″ tubing interfaces and TTL trigger signals; pyrolysis integration requires external controller synchronization.
Does the 6-month warranty cover detector performance verification?

Yes—the warranty includes functional validation of TCD sensitivity (≥1000 mV·mL/mg for H₂ in He), noise (<0.02 mV RMS), and baseline drift (<0.1 mV/hour) under specified operating conditions.
Is original PerkinElmer service documentation available?

All units include scanned copies of factory service manuals, schematics, and firmware release notes—accessible via secure download portal upon purchase.
