Overview
The Shimadzu TOC-5000A is a high-performance, combustion-catalytic oxidation total organic carbon (TOC) analyzer designed for precise quantification of organic carbon content in aqueous samples. It operates on the principle of high-temperature catalytic combustion (680–900 °C), where organic compounds are completely oxidized to CO2 in the presence of a platinum catalyst. The generated CO2 is then detected via non-dispersive infrared (NDIR) spectroscopy, delivering trace-level sensitivity and long-term measurement stability. This instrument meets the analytical rigor required for environmental monitoring, pharmaceutical water system validation (e.g., Purified Water, Water for Injection), wastewater compliance reporting, and research-grade carbon budgeting studies.
Key Features
- High-temperature catalytic oxidation (up to 900 °C) with Pt-based catalyst for complete mineralization of refractory organics
- NDIR CO2 detection with dual-beam optical design for enhanced baseline stability and drift compensation
- Auto-calibration capability using certified potassium hydrogen phthalate (KHP) or sodium benzoate standards
- Integrated solid-state sample injector with programmable rinse and purge cycles to minimize carryover
- Robust architecture engineered for unattended operation in regulated laboratory environments
- Compliant with ASTM D7573, ISO 8245, USP , and EP 2.2.44 methodologies
Sample Compatibility & Compliance
The TOC-5000A accepts liquid samples with conductivity ≤ 5 mS/cm and suspended solids < 50 mg/L. It supports direct injection of purified water, tap water, surface water, treated effluent, and low-salinity process streams. For high-conductivity or particulate-rich matrices, optional acidification, filtration, or dilution modules may be integrated. All firmware and operational protocols adhere to GLP/GMP documentation requirements, including full audit trail logging, user access control, and electronic signature support per FDA 21 CFR Part 11 when paired with compliant LIMS or data management software.
Software & Data Management
The analyzer is operated via Shimadzu’s proprietary TOC-L Series Control Software (v3.x or later), which provides real-time chromatogram visualization, method storage, calibration curve generation, and automated report export (PDF/CSV). Raw data files include timestamped metadata (operator ID, method name, injection volume, catalyst temperature, NDIR voltage output), enabling full traceability. Audit trails record all critical events—including method edits, calibration runs, and result overrides—with immutable timestamps and user attribution. Data integrity safeguards align with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).
Applications
- Pharmaceutical water system qualification (PW, WFI, SW) per USP and EU Annex 1
- Environmental compliance testing under EPA Method 415.3 and ISO 8245 for surface and groundwater
- Wastewater treatment plant performance monitoring (influent/effluent TOC load tracking)
- Chemical manufacturing process water purity verification
- Academic and industrial research on carbon cycling, biodegradation kinetics, and adsorption studies
- Validation of membrane filtration efficiency and UV oxidation systems
FAQ
Is this unit factory-refurbished or third-party refurbished?
This TOC-5000A has undergone comprehensive refurbishment by SpectraLab Scientific’s ISO 17025-accredited technical team, including full optical path cleaning, catalyst replacement, NDIR detector recalibration, gas supply system leak testing, and 72-hour operational validation under load.
Does it include original Shimadzu documentation and software licenses?
Yes — each unit ships with original English-language operation manuals, calibration certificates traceable to NIST standards, and a valid software license key for TOC-L Control Software v3.5 or later.
What maintenance history is available?
Full service logs covering the last 24 months—including catalyst replacement dates, NDIR zero/span checks, and combustion tube inspections—are provided with each instrument.
Can it be integrated into an existing LIMS environment?
Yes — the TOC-5000A supports ASTM E1384-compliant ASCII data export and OPC UA connectivity for seamless integration with major LIMS platforms including LabWare, Thermo SampleManager, and STARLIMS.
