Insights by AMPTIUS | AMP Tech Instruments

Automated Gas Chromatography for Residual Solvent and Volatile Compound Analysis

If your laboratory is struggling with manual extraction errors or baseline drift during volatile organic screening, the Agilent 7890 GC system paired with a 7697A headspace sampler delivers the ultimate automated, high-precision analysis solution. Driven by advanced Electronic Pneumatic Control (EPC) and a highly efficient oven programmable up to 450°C, this high-performance gas chromatograph ensures exceptional peak resolution and flawless retention time reproducibility. The integrated Agilent 7697A headspace sampler features an expansive 111-vial capacity tray and a precise vial oven heating up to 300°C, utilizing pressure-balanced technology to guarantee consistent analyte transfer while eliminating complex manual prep and sample carryover. It is an industry-standard, robust powerhouse perfectly optimized for environmental labs tracking trace VOCs in water or soil, and pharmaceutical facilities maintaining strict compliance for USP <467> residual solvent assays.

Agilent 7890 GC Headspace System Price and Cost of Ownership: Reliable Performance at Lower Cost

The Agilent 7890 GC System with an Agilent 7697A Headspace Sampler provides a highly cost-effective solution for laboratories performing volatile compound analysis in environmental, pharmaceutical, food and beverage, petrochemical, and forensic applications. Certified refurbished systems typically range from approximately $35,000 to $45,000, offering substantial savings compared to current-generation platforms such as the Agilent 8890 GC paired with the Agilent 8697 Headspace Sampler, which commonly range from approximately $95,000 to $115,000 depending on configuration and software options. Beyond the initial acquisition cost, laboratories should consider ongoing operational expenses, including carrier gas consumption, headspace vials, caps and septa, GC columns, inlet liners, calibration standards, preventive maintenance, software support, transfer line maintenance, and compliance-related qualification services. Long-term ownership costs remain manageable due to the proven durability of the 7890 GC platform, the reliability of the 7697A Headspace Sampler, and the widespread availability of replacement parts and service support. Purchasing a certified refurbished Agilent 7890/7697 GC Headspace System allows laboratories to significantly reduce capital expenditures while benefiting from automated sample introduction, reduced matrix interference, excellent analytical reproducibility, and dependable performance for applications such as residual solvent testing, volatile organic compound (VOC) analysis, flavor and fragrance characterization, environmental monitoring, and pharmaceutical quality control.

EPA Method 5021A: Volatile Organic Compounds in Various Sample Matrices Using Equilibrium Headspace Analysis Using the Agilent 7890 GC with 7697 Headspace Sampler

The Agilent 7890 GC System with 7697A Headspace Sampler provides a reliable, automated platform for laboratory workflows aligned with EPA Method 5021A, which uses equilibrium headspace analysis for the determination of volatile organic compounds (VOCs) in a variety of sample matrices. The 7697A Headspace Sampler automates vial equilibration, pressurization, and sample transfer, minimizing manual handling while providing consistent headspace injections and improved injection-to-injection reproducibility. By analyzing the vapor phase above the sample rather than introducing the bulk matrix directly into the GC, the technique helps reduce nonvolatile matrix loading and can protect the GC inlet and analytical column from contamination. The Agilent 7890 GC provides precise temperature control, stable carrier-gas flow, and reproducible chromatographic separation for reliable VOC quantitation. This configuration is particularly well suited for environmental laboratories analyzing water, soil, sediment, and solid samples, as well as laboratories performing contaminated-site investigations and regulatory monitoring. Combining automated equilibrium headspace sampling with dependable GC separation, the Agilent 7890/7697A platform offers a high-throughput, reproducible solution for VOC analysis where laboratories require consistent sample preparation, reduced matrix effects, and efficient EPA Method 5021A-oriented workflows.
