SRI 8610 Portable Gas Chromatograph

Overview

The SRI 8610 Portable Gas Chromatograph is an engineered solution for field-deployable and laboratory-based quantitative analysis of volatile and semi-volatile organic compounds (VOCs and SVOCs). Based on capillary gas chromatography with programmable temperature vaporization (PTV) and precision electronic pressure control (EPC), the instrument delivers high reproducibility and method traceability in compliance with U.S. Environmental Protection Agency (EPA) standard methods—including Method 8010 (GC/FID for petroleum hydrocarbons), Method 8015 (GC/FID for gasoline-range organics), and Method 8021 (GC/ECD for chlorinated pesticides and PCBs). Its compact footprint (49.5 × 36.8 × 34.3 cm) and ruggedized chassis support mobile deployment in vehicles, environmental monitoring trailers, emergency response units, and fixed-lab environments without compromising analytical integrity.

Key Features

• Electronic Pressure Control (EPC) across all carrier and auxiliary gas lines—enabling precise, repeatable flow and pressure programming from 0 to 80 psi at up to 90 psi/min ramp rate.
• Column oven with ambient-to-400 °C operation, 0.01 °C setpoint resolution, and ±0.1 °C thermal stability over time; supports infinite multi-segment temperature ramping and isothermal holds.
• Modular detector architecture supporting up to six detectors simultaneously—selected from a library of 16 validated configurations including FID, ECD, TCD, NPD, FPD, HID, DELCD, PID, CCD, RGD, and hybrid combinations (e.g., FID-DELCD, NPD-DELCD).
• Twelve injection modalities—programmable and configurable in parallel—covering direct liquid/gas injection, purge-and-trap, thermal desorption, headspace (manual and autosampler), programmed temperature vaporization (PTV), split/splitless, and air concentrator interfaces.
• Integrated LED front-panel display showing real-time column oven temperature, detector temperatures, and critical gas pressures—enabling standalone operation without external PC.
• PeakSimple v4.x data system: four-channel acquisition, baseline correction algorithms, peak integration with retention time locking, and export-compatible output (CSV, ASCII, AIA format) for LIMS integration.

Sample Compatibility & Compliance

The SRI 8610 accommodates solid, liquid, and gaseous matrices per EPA-compliant workflows. It is routinely deployed for analysis of drinking water (benzene, toluene, ethylbenzene, xylenes), soil and groundwater (chlorinated solvents, PAHs), agricultural samples (organophosphate pesticides, rodenticides), and industrial emissions (halogenated VOCs, sulfur compounds). The system meets requirements for GLP and GMP-aligned laboratories through audit-ready data handling, detector calibration logging, and method version control. While not inherently 21 CFR Part 11 compliant out-of-the-box, its PeakSimple software supports configuration for electronic signature implementation and audit trail generation when paired with validated IT infrastructure.

Software & Data Management

PeakSimple v4.x serves as the primary acquisition and processing engine—designed specifically for GC instrumentation with emphasis on robustness in variable environmental conditions. The software provides full remote control of oven temperature, detector parameters, valve sequencing, and EPC settings via USB 2.0 interface. All raw chromatograms are timestamped and stored with metadata (operator ID, method name, injection sequence, detector configuration). Data export formats include ASTM E1319-compliant ASCII, AIA/ANDI (.cdf), and CSV for downstream statistical analysis or regulatory reporting. Optional add-ons enable automated calibration curve generation, QC flagging based on USP system suitability criteria, and batch report templating aligned with ISO/IEC 17025 documentation standards.

Applications

• Environmental field screening: On-site quantification of BTEX, chlorinated ethenes, and pesticides in water, soil, and ambient air using EPA 8015/8021-compliant methods.
• Industrial hygiene: Real-time monitoring of workplace air for VOC exposure limits (OSHA PELs, ACGIH TLVs) using FID or PID detection.
• Food safety: Residue analysis of fumigants (e.g., methyl bromide) and processing contaminants (e.g., chloropropanols) in raw and processed commodities.
• Forensic toxicology: Detection of volatile poisons (e.g., phosphine, cyanide derivatives) and illicit drug precursors via ECD, NPD, or dual-FPD configurations.
• Petroleum QA/QC: Hydrocarbon fingerprinting in crude oil, refined fuels, and lubricants using simulated distillation (SIMDIS) protocols with FID and TCD co-detection.

FAQ

Is the SRI 8610 certified for use in regulated environmental testing?
Yes—the instrument is validated for EPA Methods 8010, 8015, and 8021 when operated with appropriate columns, detectors (e.g., FID for hydrocarbons, ECD for halogenated compounds), and calibration standards traceable to NIST SRMs.
Can the system be powered from a vehicle’s 12 V DC supply?
Yes—optional DC power interface kits allow stable operation from automotive or generator sources without performance degradation.
What is the typical warm-up and equilibration time for the column oven?
From ambient to 300 °C: ≤12 minutes; temperature stabilization to ±0.1 °C occurs within 2 minutes post-ramp under standard lab conditions.
Does the system support unattended overnight analysis?
Yes—when equipped with an autosampler (liquid or headspace) and configured with method sequences in PeakSimple, the 8610 supports fully automated batch runs with alarm-triggered shutdown and log-file generation.
Are replacement consumables and service parts available globally?
SRI maintains an authorized distributor network across North America, Europe, and APAC; all GC columns, septa, liners, detector components, and EPC modules are stocked and shipped with documented lot traceability.
