Overview
The O.I. Analytical 1020A Total Organic Carbon (TOC) Analyzer is a benchtop, high-temperature combustion-based analytical system engineered for precise, trace-level quantification of carbon species in aqueous matrices. It operates on the principle of catalytic high-temperature oxidation (up to 950 °C) followed by non-dispersive infrared (NDIR) detection—a method validated and widely accepted under U.S. EPA Methods 415.3, 9060A, and Standard Methods 5310C. The instrument simultaneously determines Total Carbon (TC), Total Inorganic Carbon (TIC), Total Organic Carbon (TOC = TC − TIC), and Purgeable Organic Carbon (POC) through programmable, sequential acidification, sparging, and combustion steps. Its robust architecture supports routine analysis of complex, high-carbon-content samples—including wastewater, seawater, industrial effluents, and pharmaceutical process water—without matrix-induced carryover or memory effects when operated per manufacturer-recommended maintenance protocols.
Key Features
- High-temperature combustion furnace with platinum catalyst, adjustable from 200 °C to 950 °C in 1 °C increments
- NDIR detector with 11 cm optical path length flow cell, optimized for sensitivity and long-term stability
- Multi-range detection capability: 25 ppb to 10,000 ppm C (as carbon), with method-dependent calibration linearity
- Precision performance: ≤2% RSD for TC/TIC/TOC at concentrations from 100 ppb to 5,000 ppm; ≤3% RSD for POC
- Flexible sample introduction: Fixed-volume quantitative loops (25, 50, 100, 200, and 400 µL), syringe aspiration, or optional 14- or 40-position autosampler (Model 1051)
- Dual-gas system: Ultra-high-purity oxygen (≥99.998%, <1 ppm CO₂/CO/THC, 550 mL/min) for oxidation; UHP nitrogen (same purity specs, 70 mL/min) for POC sparging
- Acid reagent delivery: Automated 5% v/v phosphoric acid (H₃PO₄) dosing (0.2 mL per sample)
- Compact footprint: 43.2 cm H × 34.3 cm W × 55.9 cm D (17″ × 13.5″ × 22″)
Sample Compatibility & Compliance
The 1020A accommodates aqueous samples containing suspended solids up to 400 µm in diameter, provided filtration or centrifugation is applied prior to analysis where particulate interference is suspected. It complies with key regulatory frameworks governing environmental and pharmaceutical water quality testing, including U.S. EPA 40 CFR Part 136, ASTM D5903, ISO 8245, and USP . When configured with audit-trail-enabled WinTOC software and operated under documented SOPs, the system supports GLP and GMP environments. Data integrity is reinforced through secure user access controls, electronic signature support, and full 21 CFR Part 11 compliance readiness—subject to site-specific validation and configuration review.
Software & Data Management
Controlled via WinTOC—a Windows-based application—the 1020A delivers comprehensive method setup, real-time signal monitoring, peak integration, calibration curve generation, and automated report export (CSV, PDF, or printer-ready formats). The software supports multi-point calibration, bracketing standards, blank subtraction, and drift correction algorithms. All acquisition parameters, calibration history, operator logins, and result metadata are time-stamped and stored locally with configurable backup intervals. RS-232-C serial interface enables integration into LIMS environments; parallel port output supports legacy dot-matrix printers for hard-copy audit trails.
Applications
- Regulatory compliance testing of municipal and industrial wastewater (EPA NPDES permits)
- Monitoring of purified water (PW) and water-for-injection (WFI) in pharmaceutical manufacturing
- Carbon load assessment in desalination and membrane filtration systems
- Research-scale carbon cycling studies in marine and estuarine environments
- Validation of cleaning-in-place (CIP) efficacy in biopharmaceutical facilities
- Leachate characterization from landfill and remediation sites
FAQ
Is this unit fully refurbished and tested prior to shipment?
Yes. Each 1020A undergoes full functional verification at SpectraLab Scientific’s ISO 9001-certified refurbishment facility, including furnace temperature calibration, NDIR zero/span verification, gas flow validation, and multi-point TOC recovery testing using certified reference materials.
What documentation accompanies the instrument?
You receive a Certificate of Inspection, complete service history, updated firmware version log, and a 6-month limited warranty covering parts and labor for defects in materials or workmanship.
Can the system be upgraded with modern data security features?
While the base hardware does not support embedded electronic signatures, WinTOC v3.2+ (included) meets 21 CFR Part 11 requirements when deployed on validated Windows OS platforms with domain-level authentication and encrypted network storage.
Are consumables and spare parts available?
Yes. We maintain inventory of critical spares—including quartz combustion tubes, NDIR cells, catalyst beds, and acid reagent kits—as well as OEM-compatible autosampler components and tubing sets.
Does the analyzer require annual recalibration?
Per O.I. Analytical recommendations and ISO/IEC 17025 guidelines, annual performance verification is advised; we offer remote-assisted or on-site calibration services with NIST-traceable standards.
