HP 5890 Series II Gas Chromatograph with 7673 Autosampler

Overview

The HP 5890 Series II Gas Chromatograph is a robust, benchtop analytical instrument engineered for high-resolution separation and quantitative analysis of volatile and semi-volatile organic compounds. Based on capillary and packed column gas chromatography principles, it employs precise temperature-programmed oven control, pressure-regulated carrier gas flow, and detector-specific signal conditioning to deliver consistent retention time reproducibility and peak resolution. Designed for routine QC laboratories and research environments, the system integrates seamlessly with the HP 7673 automatic liquid sampler—enabling unattended analysis of up to 50 samples per sequence with programmable injection volume, wash cycles, and needle depth calibration. Its modular architecture supports dual-detector configurations and multiple inlet types, making it adaptable to evolving method development requirements without hardware replacement.

Key Features

• Temperature-controlled oven with ±0.1 °C stability over 30–400 °C range and ramp rates up to 40 °C/min
• Electronic pneumatic control (EPC) for carrier gas (He, H₂, or N₂) with pressure and flow precision better than ±0.1 psi and ±0.1 mL/min
• Configurable inlet systems: Split/splitless (SSI) and programmed temperature vaporizer (PPI) for broad volatility coverage and thermal labile compound integrity
• Flame ionization detector (FID) with linear dynamic range >10⁷ and detection limit <1 pg C/sec; thermal conductivity detector (TCD) with helium or hydrogen reference gas and adjustable bridge current
• HP 7673 autosampler featuring syringe-based liquid injection, integrated vial tray (up to 50 positions), solvent wash station, and positional repeatability <±0.1 mm
• Front-panel keypad and LCD display for standalone method setup; fully controllable via legacy HP ChemStation software on Windows-based PCs

Sample Compatibility & Compliance

The HP 5890 Series II accommodates liquid, gaseous, and headspace-derived samples across pharmaceutical, environmental, petrochemical, and food safety applications. It supports standard 2 mL crimp-top vials and accommodates derivatized, extracted, or diluted matrices compatible with GC injection protocols. While originally designed prior to modern regulatory software mandates, the system—when operated with validated HP ChemStation Gx edition (revision A.03.04 or later) and configured with audit trail logging, user access controls, and electronic signature support—can meet core elements of FDA 21 CFR Part 11 for traceable data acquisition in GLP and GMP environments. Method transfer compliance with ASTM D3606 (gasoline aromatics), ISO 10301 (petroleum hydrocarbons), and USP (chromatography) is routinely demonstrated using this platform.

Software & Data Management

Data acquisition, processing, and reporting are managed through HP ChemStation software—a Windows-native application supporting real-time chromatogram visualization, peak integration with customizable baseline algorithms, calibration curve generation (linear, quadratic, or weighted), and report templating. Raw data files (.D format) preserve all acquisition parameters, detector signals, and sequence logs for retrospective review. The software supports LIMS connectivity via ASCII export and OLE automation, enabling integration into enterprise laboratory informatics ecosystems. Audit trail functionality records user actions—including method edits, reprocessing events, and result approvals—with timestamps and operator IDs, satisfying documentation requirements for internal QA audits and external regulatory inspections.

Applications

• Residual solvent analysis in APIs per ICH Q3C guidelines
• VOC profiling in ambient air, soil extracts, and drinking water (EPA Methods 502.2, 624, 8240)
• Fatty acid methyl ester (FAME) quantification in biodiesel feedstocks (ASTM D6584)
• Hydrocarbon type analysis (PIONA) in gasoline and naphtha streams
• Essential oil composition mapping using capillary polar columns (e.g., DB-WAX)
• Impurity profiling in polymer additives and plasticizers

FAQ

Is the HP 5890 Series II still supported by Agilent for service or parts?
Agilent Technologies maintains limited legacy support for the 5890 platform, including critical spare parts (injector seals, detector jets, oven heaters) and certified field service for preventive maintenance and performance qualification. Extended warranty and service contracts are available through authorized Agilent partners.

Can modern data systems interface with the HP 5890 Series II?
Yes—via RS-232 or GPIB connectivity, the instrument communicates with current versions of OpenLab CDS or Chromeleon when configured with appropriate interface modules and driver firmware. Migration paths from ChemStation .D files to universal formats (e.g., ANDI/NetCDF) are well documented.

What column dimensions and phases are compatible?
The system accepts standard 1/4-inch packed columns and 0.1–0.53 mm ID fused-silica capillary columns up to 60 m in length. Common stationary phases include DB-5ms, HP-INNOWAX, DB-1, and DB-1701, with temperature limits aligned to column manufacturer specifications.

Does the 7673 autosampler support cold injection or large-volume injection?
No—the HP 7673 is optimized for ambient-temperature liquid-phase injection only. For cold on-column or large-volume injection (LVI), retrofitting with an HP 7673 CTC or third-party PTV module is required and must be validated per SOP.
