Shimadzu TOC-V CSN Total Organic Carbon Analyzer (Refurbished)

Overview

The Shimadzu TOC-V CSN is a high-precision, benchtop total organic carbon analyzer engineered for reliable quantification of total carbon (TC), inorganic carbon (IC), and derived total organic carbon (TOC = TC − IC) in aqueous samples. It employs high-temperature catalytic combustion at 680 °C—optimized for complete oxidation of refractory organic compounds—followed by highly selective non-dispersive infrared (NDIR) detection of the evolved CO₂. This measurement architecture meets the fundamental performance requirements of major international standards, including JIS K 0102 (Japan), ASTM D7573 (U.S.), ISO 8245 (International), USP (pharmaceutical water quality), and EPA Method 415.3 (drinking water and wastewater). As a refurbished unit sourced from North American laboratory decommissioning cycles and rigorously reconditioned by SpectraLab Scientific, the TOC-V CSN retains full functional integrity, factory-calibrated linearity, and system-level traceability—all verified under ISO/IEC 17025-aligned test protocols prior to release.

Key Features

• High-temperature combustion module with Pt catalyst and quartz combustion tube—ensuring >99% oxidation efficiency across diverse organic matrices (e.g., humic acids, surfactants, pharmaceutical residues)
• Dual-detector NDIR system with automatic baseline correction and zero-point stabilization, delivering sub-ppb detection limits (LOD: 4 µg/L C) and linear dynamic range from 4 µg/L to 30,000 µg/L C
• Integrated ASI-V autosampler with 64-position vial capacity, programmable rinse cycles, and low-volume injection (0.2–1.0 mL) to minimize sample consumption and cross-contamination
• Robust hardware architecture designed for continuous operation in regulated environments—compliant with GLP/GMP documentation workflows and 21 CFR Part 11 audit-trail readiness when paired with validated TOC-Control software
• Self-diagnostic firmware with real-time status monitoring of combustion temperature, gas flow rates, detector signal stability, and catalyst health indicators

Sample Compatibility & Compliance

The TOC-V CSN accommodates a broad spectrum of aqueous matrices without pretreatment: ultrapure water (UPW), pharmaceutical process water (PW, WFI), municipal and industrial wastewater, groundwater, surface water, and cleaning validation rinse solutions. Sample conductivity up to 1,500 µS/cm is supported via integrated acidification and sparging for IC removal. All operational parameters—including method sequences, calibration curves, and QC check results—are stored with timestamped metadata, enabling full compliance with ISO 17025 clause 7.7 (result reporting), USP system suitability criteria, and FDA expectations for data integrity in regulated QC labs. The instrument’s mechanical and electronic refurbishment includes replacement of critical wear components (combustion tube, catalyst, NDIR cell windows, peristaltic pump tubing) and recalibration against NIST-traceable sucrose and sodium bicarbonate standards.

Software & Data Management

Operation is managed through Shimadzu’s TOC-Control V3.x software, installed on a dedicated Windows-based PC included in the package. The software supports method development, multi-point calibration (linear or quadratic), automated system suitability testing (SST), and customizable report generation (PDF/CSV/XLSX). Audit trails record all user actions—including parameter changes, calibration events, and result overrides—with immutable timestamps and operator IDs. Data export conforms to LIMS-ready formats; raw detector signals, integration parameters, and diagnostic logs are preserved in native .tdf format for retrospective review. Optional IQ/OQ documentation packages are available upon request to support installation qualification and operational qualification in GxP environments.

Applications

• Pharmaceutical manufacturing: Routine TOC monitoring of purified water (PW), water for injection (WFI), and clean-in-place (CIP) final rinse water per USP and EU Annex 1 requirements
• Environmental laboratories: Compliance testing for drinking water (EPA 415.3), wastewater discharge permits, and contaminated site remediation verification
• Power generation: Boiler feedwater and condensate TOC surveillance to prevent corrosion and deposition in steam cycles
• Microelectronics: UPW certification in semiconductor fabs where organic contamination below 10 ppb C impacts wafer yield
• Academic and contract research: Method development for emerging contaminants (e.g., PFAS precursors, microplastic leachates) requiring robust oxidation recovery

FAQ

Is this unit fully refurbished and performance-verified?
Yes. Each TOC-V CSN undergoes a 12-point functional validation protocol—including combustion efficiency verification, NDIR linearity assessment, autosampler precision testing, and SST pass/fail confirmation—prior to shipment.
What documentation accompanies the instrument?
You receive a Certificate of Refurbishment, calibration records (traceable to NIST standards), system verification report, and original Shimadzu operation manuals (English). IQ/OQ templates are available as optional add-ons.
Can this analyzer be integrated into an existing LIMS environment?
Yes. TOC-Control software supports ODBC-compliant database export and configurable CSV output formats compatible with major LIMS platforms.
Does the 6-month warranty cover parts and labor onsite?
The warranty covers all parts and labor for defects in materials or workmanship. Remote diagnostics are provided at no cost; onsite service is available under separate service agreement terms.
Are consumables and spare parts still available for this model?
Shimadzu continues to supply combustion tubes, catalyst cartridges, NDIR cells, and ASI-V syringe assemblies globally. SpectraLab maintains a strategic inventory of high-failure-rate consumables for rapid fulfillment.
