Advanced Ion Optics and Proven GC-MS Performance for Trace-Level Analysis
If your laboratory is looking for a widely deployed, highly reliable GC-MS platform with advanced ion optics and outstanding analytical performance, the Agilent 7890A GC with the 5975C TAD GC/MS System and 7693 Autosampler is an excellent choice. This proven configuration combines the 7890A Gas Chromatograph, featuring an oven temperature range from ambient +4 °C to 450 °C and advanced Electronic Pneumatics Control (EPC) with rapid oven cooling, with the 5975C TAD Mass Selective Detector, offering a mass range of 1.6 to 1050 amu for comprehensive qualitative and quantitative analysis across a broad range of compounds. The 5975C's Triple-Axis Detector (TAD) incorporates a unique curved ion optics design that physically shields the electron multiplier from neutral particles while efficiently transmitting analyte ions, resulting in lower baseline noise, improved signal-to-noise ratios, and enhanced sensitivity for trace-level applications. The 7693 Autosampler delivers fast, highly reproducible injections that improve quantitative precision and support unattended, high-throughput workflows. Compared to earlier GC-MS platforms, the 7890A provides improved pressure control, greater retention time stability, and enhanced system reliability for demanding analytical methods. For testing startups, contract research organizations (CROs), academic core facilities, and routine analytical laboratories, a certified refurbished Agilent 7890A/5975C/7693 configuration delivers the same legally defensible analytical results as significantly newer systems while dramatically reducing capital investment and maintaining dependable long-term performance.
Agilent 7890A/5975C TAD GCMS System Price and Cost of Ownership: Reliable Performance at Lower Cost
The Agilent 7890A GC with the 5975C Triple-Axis Detector (TAD) GC/MS System and 7693 Autosampler provides a high-performance, cost-effective solution for laboratories requiring reliable trace-level GC-MS analysis. Certified refurbished systems typically range from $28,000 to $46,000, offering substantial savings compared to a comparable new Agilent 8890 GC with a 5977C GC/MSD and 7693A Autosampler, which commonly ranges from $85,000 to $115,000, depending on configuration, software, and accessory options. In addition to the initial acquisition cost, laboratories should consider ongoing operational expenses, including GC columns, carrier gases (helium, hydrogen, or nitrogen), inlet liners, septa, ferrules, autosampler syringes, filaments, electron multipliers, ion source consumables, turbomolecular and roughing pump maintenance, vacuum pump oil, calibration standards, tuning compounds, software support, preventive maintenance, and instrument qualification or compliance services. Long-term ownership costs remain highly manageable due to the proven durability of the 7890A GC platform, the robust design of the 5975C TAD mass spectrometer, and the widespread availability of affordable replacement parts and third-party service support. Straightforward preventative maintenance procedures help minimize downtime while extending instrument lifespan. Purchasing a certified refurbished Agilent 7890A 5975C TAD GC/MS System with a 7693 Autosampler enables laboratories to significantly reduce capital expenditures while benefiting from advanced Triple-Axis Detector technology, dependable trace-level sensitivity, automated sample introduction, and proven GC-MS performance for routine quality control, regulatory compliance, and demanding analytical workflows.
High-Throughput Clinical & Forensic Toxicology Using the Agilent 7890A/5975C/7693 TAD GCMS System
The Agilent 7890A GC with the 5975C Triple-Axis Detector (TAD) GC/MS System and 7693 Autosampler is an excellent platform for high-throughput clinical and forensic toxicology laboratories requiring reliable identification and quantitation of drugs, metabolites, and toxic compounds in complex biological matrices. The 7890A Gas Chromatograph, featuring an oven temperature range from ambient +4 °C to 450 °C and precision Electronic Pneumatics Control (EPC), delivers highly reproducible chromatographic separations, while the 5975C TAD Mass Selective Detector, with a mass range of 1.6 to 1050 amu, provides exceptional sensitivity and broad compound coverage for comprehensive toxicological screening. Its advanced Triple-Axis Detector (TAD) ion optics minimize background noise by shielding the detector from neutral contaminants, resulting in improved signal-to-noise ratios and lower detection limits for trace-level analytes. The 7693 Autosampler supports rapid, highly reproducible automated injections, enabling continuous unattended operation and maximizing laboratory throughput. This configuration is well suited for the analysis of drugs of abuse, prescription medications, opioids, benzodiazepines, antidepressants, stimulants, toxic alcohols, and other forensic toxicants in blood, urine, and tissue samples. Combining proven Agilent reliability, robust GC-MS performance, automated sample handling, and excellent analytical reproducibility, the Agilent 7890A/5975C/7693 TAD GC/MS System provides clinical, forensic, and reference laboratories with a dependable, high-throughput solution for routine toxicology testing, confirmation analyses, and legally defensible analytical results.
