Overview
The Agilent HP 5890 II Gas Chromatograph (GC), integrated with the Gerstel MultiPurpose Sampler (MPS), constitutes a robust, field-proven platform for quantitative and qualitative analysis of volatile and semi-volatile organic compounds. Engineered for precision and operational stability, this second-hand system retains full functional integrity after comprehensive refurbishment by SpectraLab Scientific — including leak testing, detector calibration verification, column oven thermal profiling, and firmware validation against original HP/Agilent specifications. The instrument operates on the fundamental principle of gas-phase separation: analytes are volatilized in a temperature-controlled inlet, partitioned across a capillary column under carrier gas flow (N₂, He, or H₂), and detected based on physicochemical response (e.g., flame photometric detection). Designed for laboratory environments requiring regulatory traceability, the system supports method transfer from legacy HP 5890 workflows and remains compatible with modern data systems via analog/digital I/O and RS-232 interfaces.
Key Features
- Thermally stable column oven with operating range from 4°C above ambient to 450°C; programmable ramp rates from 0.1 to 70°C/min; up to three independent temperature ramps per run
- Dual-detector configuration supporting simultaneous FPD (Flame Photometric Detector) operation in sulfur (S) and phosphorus (P) modes — S sensitivity: 20 pg S/sec, selectivity >10⁵ g S/g C; P sensitivity: 0.9 pg P/sec, selectivity >10⁶ g P/g C
- Multi-mode inlet with split/splitless capability; septum purge flow: 3 mL/min (adjustable); maximum column OD: 1.2 mm; back-pressure control enables independent split flow regulation without altering column flow
- Gerstel MPS robotic autosampler featuring five independently heated zones (up to 400°C in 1°C increments), enabling thermal desorption, headspace, and liquid injection protocols within a single hardware platform
- FPD combustion options: air/H₂ or O₂/H₂ modes; real-time flame status indicator; push-button ignition; detector signal monitoring active only when flame is verified
- Fully refurbished mechanical and electronic subsystems — including GC oven insulation, detector jet assemblies, EPC modules, and MPS syringe drive mechanisms — validated per ISO/IEC 17025-aligned internal QA checklist
Sample Compatibility & Compliance
This GC-MPS configuration accommodates a broad spectrum of sample matrices, including environmental water extracts (EPA Method 508/524), petrochemical distillates, pesticide residues in food commodities, and pharmaceutical residual solvents (ICH Q3C). Capillary columns up to 100 m length and 0.53 mm ID are fully supported. All refurbished units undergo baseline noise and retention time reproducibility testing (RSD <0.5% for n-alkane standards). While not supplied with current FDA 21 CFR Part 11-compliant software, the hardware architecture permits integration with compliant chromatography data systems (CDS) such as OpenLAB CDS or Chromeleon via standard analog output and relay-controlled event triggering. Documentation includes full refurbishment log, detector performance report, and certificate of functional verification.
Software & Data Management
The HP 5890 II operates natively with HP ChemStation Rev. A.03.04 or earlier — compatible with Windows XP Professional (32-bit) or Windows 7 Embedded. SpectraLab provides optional migration support to modern CDS platforms through certified third-party integration partners. Raw data files (.DAT) retain full spectral and timing metadata required for audit trails. Instrument control parameters (oven program, detector gain, inlet pressure) are stored in human-readable ASCII format, facilitating GLP/GMP-compliant archiving. Firmware versions are verified against Agilent’s public release notes; no unauthorized modifications are present.
Applications
- Environmental analysis: organophosphorus pesticides, polycyclic aromatic hydrocarbons (PAHs), chlorinated hydrocarbons
- Petrochemical QA/QC: hydrocarbon type analysis (HTA), sulfur speciation in fuels (ASTM D5453)
- Food safety: mycotoxin screening, flavor compound profiling, adulterant detection
- Pharmaceutical manufacturing: residual solvent quantification per USP , cleaning validation swab extract analysis
- Forensic toxicology: volatile substance identification (e.g., ethanol, acetone, isopropanol) in blood headspace
FAQ
Is this unit eligible for extended warranty or service contract?
Yes — SpectraLab Scientific offers optional 12- or 24-month extended service agreements covering parts, labor, and remote diagnostics. Contracts include annual preventive maintenance visits.
Can the Gerstel MPS be upgraded to support dynamic headspace or thermal desorption?
Yes — all refurbished MPS units retain full hardware compatibility with Gerstel TD-2, DHS, and SPME modules; upgrade kits and installation services are available upon request.
What documentation accompanies the system?
Each unit ships with a Certificate of Refurbishment, detector performance report (including FPD S/P calibration curves), GC oven thermal uniformity test data, and full electrical safety inspection record.
Are consumables and spare parts included?
No — but SpectraLab maintains inventory of OEM-compatible liners, septa, FPD jets, and MPS syringes; volume pricing is available upon order.
Does the system meet current ISO/IEC 17025 requirements for accredited labs?
The hardware meets metrological requirements for routine use; final accreditation depends on lab-specific validation protocol execution (IQ/OQ/PQ), which SpectraLab can support with documented templates and on-site assistance.
