Price and cost of ownership of Agilent 7890B Gas Chromatograph GC System w/ 7693 Autosampler, Tray & Software

Investing in an Agilent 7890B Gas Chromatograph (GC) System with 7693 Autosampler, Tray, and Software is a smart move for labs needing high-throughput, precise, and reliable chromatographic performance. A brand new system costs approximately $123,000, while a certified refurbished unit can be acquired for around $35,000, offering a substantial reduction in upfront investment. The 7890B GC is widely trusted for its exceptional retention time repeatability, robust oven programming, and compatibility with multiple detector types (FID, TCD, ECD, and MS). The 7693 Autosampler automates sample injection and tray handling, significantly improving lab productivity and minimizing human error. The integrated software supports advanced method development, data acquisition, and regulatory compliance, which is especially valuable in pharmaceutical, environmental, and petrochemical applications. Long-term costs include gases (helium, hydrogen), columns, inlet liners, septa, and regular consumables. Maintenance of the autosampler and injector system is also essential to avoid downtime and ensure consistency in performance. Opting for a certified refurbished 7890B system provides excellent value—combining high-end functionality with cost-efficiency. Backed by warranty and thorough revalidation, it’s an ideal solution for labs aiming to scale up capabilities while staying within budget.

Agilent 7890B GC with 7693 Autosampler: Trusted for Biodiesel, SVOCs, and Residue Testing

The Agilent 7890B Gas Chromatograph (GC) System with 7693 Autosampler, Tray, and Software is a highly versatile analytical platform designed to support a wide range of detectors for diverse laboratory applications. It is fully compatible with key detectors such as the Flame Ionization Detector (FID), Electron Capture Detector (ECD), Thermal Conductivity Detector (TCD), Nitrogen Phosphorus Detector (NPD or TSD), Mass Selective Detector (MSD), Flame Photometric Detector (FPD), Pulsed Flame Photometric Detector (PFPD), and Sulfur Chemiluminescence Detector (SCD). Each detector provides unique selectivity, for example, FID for hydrocarbons, ECD for halogenated compounds, TCD for permanent gases, NPD for nitrogen/phosphorus-containing drugs or pesticides, FPD/SCD/PFPD for sulfur and phosphorus compounds, and MSD for complex mixtures requiring compound identification. This compatibility allows laboratories to configure the 7890B system for a wide range of analyses in pharmaceuticals, environmental monitoring, food safety, petrochemicals, forensics, and industrial quality control. The Agilent 7890B Gas Chromatograph with the 7693 Autosampler is a reliable system that supports important testing methods like ASTM D6584 and EPA Method 8270D. In ASTM D6584, the 7890B GC with FID is used to quantify free and bonded glycerin in biodiesel after derivatization. The method ensures biodiesel meets fuel quality standards, and the 7693 autosampler enables reproducible sample injections for improved accuracy and throughput. EPA Method 8270D is used to analyze semi-volatile organic compounds (SVOCs) in environmental samples such as water, soil, and sludge. After undergoing extraction and concentration, these samples are introduced into the Agilent 7890B GC system coupled with a Mass Selective Detector (MSD), which enables precise identification and quantification of a wide range of target pollutants, including phthalates, pesticides, and polycyclic aromatic hydrocarbons (PAHs). The MSD’s mass spectral capabilities are essential for distinguishing co-eluting compounds and meeting the method’s identification criteria. With the 7693 autosampler providing reproducible and consistent injections, the system supports compliance with strict QA/QC requirements. This configuration is well suited for environmental testing laboratories performing regulated SVOC analyses with a need for high sensitivity, selectivity, and data integrity.
