Thermo Fisher Finnigan Surveyor Plus High-Performance Liquid Chromatography System

Overview

The Thermo Fisher Finnigan Surveyor Plus is a high-performance liquid chromatography (HPLC) system engineered for precision, robustness, and method flexibility in regulated and research-intensive laboratory environments. Built upon Thermo Fisher’s legacy in analytical instrumentation, the Surveyor Plus platform integrates core HPLC components—including a quaternary solvent delivery system, autosampler, column oven, and multiple detector options—into a unified architecture optimized for both standalone operation and seamless coupling with mass spectrometry (LC-MS). Its design emphasizes short cycle times, high sample throughput, and reproducible gradient formation, making it suitable for method development, stability-indicating assays, impurity profiling, and routine QC/QA applications. The system employs conventional high-pressure liquid chromatography principles, utilizing precise piston-driven pumping, low-dead-volume fluidics, and thermally stabilized separation environments to ensure retention time stability and peak shape fidelity across extended runs.

Key Features

• Quaternary solvent manager enabling precise, low-pulse gradient elution with four independent solvent channels and real-time proportioning control
• Integrated column oven with programmable temperature range (typically 5–80 °C), ensuring consistent retention behavior and improved method ruggedness
• UV/Vis photodiode array detector (PDA) enhanced by LightPipe™ optical path technology—delivering up to 5× higher sensitivity versus conventional PDA detectors without compromising spectral resolution
• Dedicated refractive index (RI) detector for non-UV-absorbing analytes such as carbohydrates, polymers, and excipients
• Autosampler with variable injection volumes (typically 0.1–100 µL), needle wash capability, and temperature-controlled sample tray (4–40 °C)
• Full system integration via Thermo Scientific ChromQuest Chromatography Data System, compliant with FDA 21 CFR Part 11 requirements including electronic signatures, audit trails, and user access controls
• Modular hardware design supporting future upgrades—including direct LC-MS interface compatibility with Thermo Finnigan MS platforms (e.g., LCQ, TSQ series)

Sample Compatibility & Compliance

The Surveyor Plus accommodates a broad range of sample matrices—including pharmaceutical actives, biological fluids, environmental extracts, and polymer solutions—provided they meet standard HPLC solubility and filtration criteria (e.g., <0.45 µm filtration prior to injection). It supports reversed-phase, normal-phase, ion-exchange, and size-exclusion chromatographic modes using commercially available columns (3–5 µm particles, 2.1–4.6 mm ID, up to 250 mm length). All hardware and software components are designed to support GLP and GMP workflows. ChromQuest CDS provides full 21 CFR Part 11 compliance: secure user authentication, immutable audit trail logging, electronic signature validation, and role-based permission management. The system is also compatible with ISO/IEC 17025 documentation practices and aligns with relevant ASTM and USP chromatographic methodology guidelines (e.g., USP , ).

Software & Data Management

ChromQuest is a validated, Windows-based chromatography data system that serves as the central control and reporting interface for the Surveyor Plus. It enables real-time instrument control, sequence definition, peak integration, calibration curve generation, and report export in PDF, CSV, or XML formats. Audit trail functionality records all critical events—including method edits, result changes, and user logins—with timestamps and operator identification. Data integrity safeguards include automatic backup configuration, encrypted database storage, and configurable retention policies. ChromQuest supports LIMS integration via OpenLab CDS or third-party middleware, facilitating traceability across enterprise-wide quality systems. Raw data files (.raw) are stored in vendor-native format, preserving all acquisition metadata required for regulatory reprocessing and forensic review.

Applications

• Pharmaceutical QC testing per ICH Q2(R2) guidelines: assay, related substances, dissolution, and stability-indicating methods
• Biopharmaceutical characterization: mAb purity assessment, glycan profiling (with RI detection), and peptide mapping
• Food and beverage analysis: preservative quantification, vitamin profiling, and mycotoxin screening
• Environmental monitoring: pesticide residue analysis in water/soil extracts using EPA Method 8321B-compatible protocols
• Academic and contract research: method scouting, column selection studies, and preparative-scale method transfer
• Regulated biologics release testing where 21 CFR Part 11–compliant data handling is mandatory

FAQ

Is this unit fully refurbished and tested prior to shipment?
Yes. Each Surveyor Plus system undergoes functional verification at SpectraLab Scientific’s ISO 9001-certified facility, including pressure testing, gradient accuracy validation, detector linearity assessment, and autosampler precision evaluation.
