Fuli F70 Laboratory Gas Chromatograph

Overview

The Fuli F70 is a high-performance, general-purpose laboratory gas chromatograph engineered for precision, reproducibility, and operational robustness in routine and method-development environments. Built upon a modular architecture and grounded in classical gas chromatographic principles—separation based on differential partitioning of analytes between a mobile phase (inert carrier gas) and a stationary phase (capillary column)—the F70 delivers reliable retention time stability and peak shape fidelity across diverse sample matrices. Its temperature-controlled oven supports rapid thermal programming (up to 120 °C/min ramp rate) and efficient cooling (<7 minutes from 350 °C to 50 °C), enabling high-throughput analysis without compromising resolution. The system is designed for compliance-ready operation in regulated laboratories, supporting audit trails, electronic signatures, and data integrity frameworks aligned with FDA 21 CFR Part 11 and GLP/GMP documentation requirements.

Key Features

• Intuitive 7-inch capacitive touchscreen interface with multi-language support, enabling direct method creation, real-time monitoring, and instrument diagnostics without external PC dependency.
• Advanced Flow Control (AFC) technology for carrier gas, coupled with Auxiliary Flow Sensing (AFS) for split/splitless and detector gases—ensuring sub-mL/min flow stability and inter-run repeatability ≤0.5% RSD.
• Electronic Pressure Control (EPC) with 0.01 psi resolution across all pneumatic modules, minimizing baseline drift and improving retention time precision under variable ambient conditions.
• High-temperature injector (up to 400 °C) compatible with both liquid and gaseous samples, supporting standard split/splitless, on-column, and PTV injection modes via optional hardware modules.
• Modular detector bay accommodating up to three simultaneous detectors—including FID, TCD, ECD, and NPD—with independent temperature control and digital signal processing.
• Integrated self-diagnostics and guided maintenance workflows (e.g., leak detection, column conditioning, GC bake-out protocols) reduce downtime and enhance lab operational continuity.

Sample Compatibility & Compliance

The F70 accommodates volatile and semi-volatile organic compounds (VOCs/SVOCs), residual solvents, hydrocarbons, pesticides, flavor/aroma constituents, and environmental contaminants (e.g., PAHs, PCBs, chlorinated benzenes). It supports capillary columns ranging from 0.10 mm to 0.53 mm ID and lengths up to 60 m. Method validation parameters—including linearity (r² ≥ 0.999), LOD/LOQ determination per ICH Q2(R2), and system suitability testing (SST) per USP —are fully supported through embedded calculation tools. All raw data, audit logs, and method files are stored in vendor-neutral formats (e.g., .cdf, .xml) compliant with long-term archival standards. The system meets ISO/IEC 17025:2017 requirements for testing laboratories when deployed with documented SOPs and qualified accessories.

Software & Data Management

The F70 operates with ChromaLink™ 3.0, a 64-bit chromatography data system (CDS) validated for GxP environments. Key capabilities include: automated calibration curve generation with forced zero-point and quadratic weighting; customizable report templates adhering to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate); role-based user access control with password complexity enforcement; full electronic signature workflow compliant with 21 CFR Part 11 Annex 11; and secure export to LIMS via ASTM E1384 or HL7 interfaces. Audit trail records capture every parameter change, sequence modification, or result reprocessing event with timestamp, operator ID, and pre-/post-value metadata.

Applications

• Pharmaceutical QC: Residual solvent analysis (ICH Q3C), assay purity profiling, excipient compatibility studies.
• Environmental Testing: EPA Methods 502.2, 624, 8021B, and 8260D for water, soil, and air samples.
• Food & Beverage: Fatty acid methyl ester (FAME) profiling, pesticide residue screening, ethanol quantification.
• Petrochemical QA: Hydrocarbon group-type analysis (PIONA), benzene/toluene/xylenes (BTX) determination, simulated distillation (ASTM D2887).
• Academic & Method Development Labs: Column selectivity evaluation, temperature-programmed retention indexing, kinetic parameter estimation.

FAQ
