Fuli FL1092T Low-Profile Multifunctional Autosampler for Gas Chromatography

Overview

The Fuli FL1092T is a low-profile, modular autosampler engineered specifically for routine and advanced gas chromatography (GC) workflows. Its compact mechanical footprint enables seamless integration beneath standard GC oven compartments—eliminating spatial constraints common in high-density instrument racks. The system operates on precise syringe-driven liquid-phase sampling with programmable needle wash cycles, depth-controlled penetration, and pressure-balanced vial sealing to ensure quantitative transfer of volatile and semi-volatile analytes. Unlike high-tower designs, the FL1092T’s low-center-of-gravity architecture enhances mechanical stability during extended unattended runs, reducing positional drift and improving injection reproducibility across multi-day sequences.

Key Features

• 16-position sample tray configuration supporting standard 12 × 32 mm or 15 × 45 mm screw-thread or crimp-top vials
• Dual-tower variant (FL1092T-Dual) enables independent asynchronous operation—e.g., one tower loading while the other injects—maximizing GC instrument uptime
• Optional vial agitation module provides orbital shaking at adjustable speed (100–1,000 rpm) to homogenize suspended particulates or viscous matrices prior to aspiration
• Integrated temperature control: single-zone Peltier-based cooling (4–40 °C) or heating (30–100 °C) for thermal stabilization of thermolabile samples or viscosity-sensitive solvents
• Barcode reader option supports GLP-compliant sample tracking; decodes Code 128, EAN-13, and QR formats directly into sequence tables
• Rugged aluminum chassis with anodized finish ensures long-term dimensional stability under continuous lab environmental fluctuations (20–25 °C, 30–70% RH)

Sample Compatibility & Compliance

The FL1092T accommodates aqueous, organic, and mixed-solvent matrices—including acetonitrile, methanol, hexane, and chloroform—with chemically resistant stainless-steel and PTFE-wetted components. Needle assemblies are configurable for 10 µL, 25 µL, or 100 µL nominal volumes, with <±0.5% volumetric accuracy verified per ISO 8655-6. The system meets electromagnetic compatibility requirements per IEC 61326-1 and is designed for use in laboratories accredited to ISO/IEC 17025:2017. When paired with validated GC data systems (e.g., Chromeleon, OpenLab CDS), it supports audit-trail generation, electronic signatures, and user-access controls aligned with FDA 21 CFR Part 11 and EU Annex 11 expectations.

Software & Data Management

Control is executed via Fuli’s GC-Link™ driver suite—a Windows-based, COM-enabled interface compatible with third-party chromatography data systems (CDS). Sequence methods define injection volume, rinse solvent selection (up to 3 solvents), dwell time, and post-injection purge parameters. All method parameters are stored with timestamps and operator IDs. Raw log files record every mechanical event—including syringe plunger position, valve actuation timing, and temperature setpoint deviations—with .csv export capability for external QA review. Optional firmware update path ensures alignment with evolving CDS API standards (e.g., ASTM E2524-22).

Applications

• Environmental testing: EPA Method 502.2 and 8021B analysis of chlorinated hydrocarbons in groundwater extracts
• Pharmaceutical QC: Residual solvent quantification per ICH Q2(R2) guidelines using headspace-GC/FID
• Food safety: Pesticide residue screening in fruit juice matrices via GC-MS/MS with large-volume injection
• Petrochemical QA: Hydrocarbon fingerprinting in jet fuel per ASTM D1319 using dual-column parallel analysis
• Academic research: High-throughput method development requiring systematic variation of injection parameters across 96+ samples

FAQ

Can the FL1092T be retrofitted with cooling after initial purchase?
Yes—field-upgrade kits including Peltier modules, thermal insulation sleeves, and firmware patches are available through authorized Fuli service centers.
Is the dual-tower version compatible with Agilent 7890/8890 GC systems?
Yes—the FL1092T-Dual communicates via standard RS-232 and TTL-level trigger signals; Agilent-specific driver profiles are included in GC-Link™ v3.2 and later.
What maintenance intervals are recommended for the syringe and needle seal?
Fuli recommends syringe calibration verification every 500 injections and replacement of the PTFE needle seal every 2,000 injections under normal use conditions (aqueous/organic solvents, ambient temperature).
Does the barcode scanner support LIMS integration?
Yes—scanned identifiers are mapped to user-defined metadata fields (e.g., batch ID, analyst ID, expiry date) and exported via ODBC to common LIMS platforms including LabWare and STARLIMS.
How does the system handle partially filled vials or low-volume samples?
The FL1092T employs capacitive liquid-level sensing to dynamically adjust needle immersion depth; minimum sample volume is 50 µL for reliable aspiration without air draw.
