Overview
The Tailin HTY-WOT100 Total Organic Carbon (TOC) Analyzer is a laboratory-grade instrument engineered for precise, reliable quantification of organic carbon content in aqueous samples—primarily used in pharmaceutical water systems (PW, WFI, PW), environmental monitoring, municipal wastewater compliance, and research laboratories requiring regulatory-grade data integrity. It employs the well-established non-dispersive infrared (NDIR) detection principle, coupled with dual-mode oxidation (UV/persulfate), to ensure complete mineralization of refractory and labile organic compounds into CO₂, which is then quantified via high-stability NDIR sensors. This architecture delivers consistent performance across diverse sample matrices—including purified water, surface water, groundwater, and low-conductivity process streams—without interference from inorganic carbon species when operated with integrated inorganic carbon (IC) removal and subtraction protocols.
Key Features
- Regulatory-compliant software architecture: Tailin’s proprietary workstation software is designed and validated to meet FDA 21 CFR Part 11 requirements, including role-based user authentication, electronic signatures, audit trail logging (with immutable timestamps and operator attribution), and secure data storage.
- Wide dynamic measurement range: Capable of quantifying TOC concentrations from sub-ppb to 100 mg/L without manual intervention, enabled by an integrated auto-dilution module that maintains linearity and precision across low-, mid-, and high-range applications.
- Modular automation compatibility: Designed for seamless integration with Tailin’s ASE-series autosamplers (e.g., ASE-18C, ASE-24, ASE-70C), supporting unattended batch analysis, multi-point calibration, and scheduled system suitability testing.
- Robust oxidation efficiency: Dual oxidation—comprising 185/254 nm UV irradiation and catalyzed persulfate addition—ensures >95% oxidation efficiency for recalcitrant organics such as humic acids, surfactants, and pharmaceutical residuals, as verified per ISO 8245 and USP .
- Compact benchtop footprint: With dimensions of 550 × 450 × 530 mm, the HTY-WOT100 fits standard laboratory fume hoods or QC workstations while maintaining full internal reagent management and waste handling capabilities.
Sample Compatibility & Compliance
The HTY-WOT100 accommodates liquid samples with conductivity ≤5 µS/cm and total suspended solids (TSS) <1 mg/L. It complies with multiple national and international standards, including Chinese Environmental Protection Standard HJ 501–2009 (determination of TOC in water by persulfate/NDIR), metrological verification regulation JJG 821–2005, and aligns with pharmacopeial methodologies (USP , EP 2.2.44, JP 2.59). Its design supports GLP and GMP environments through hardware-enforced data integrity controls and configurable report templates compliant with ISO/IEC 17025 documentation requirements.
Software & Data Management
The embedded Windows-based control software provides real-time chromatogram visualization, method parameterization (oxidation time, injection volume, dilution factor), and automated calculation of TC, IC, and TOC (TC − IC). All raw sensor outputs, calibration logs, system suitability results, and user actions are stored in encrypted SQLite databases with SHA-256 hashing. Audit trails are exportable in PDF/A-1b format and support third-party LIMS integration via OPC UA or CSV batch export. Software validation documentation (IQ/OQ/PQ protocols) is provided upon request for regulated users.
Applications
- Pharmaceutical water system monitoring: Routine TOC verification of Purified Water (PW), Water for Injection (WFI), and Clean Steam condensate per FDA and EU GMP Annex 1.
- Environmental compliance: Monitoring of drinking water sources, effluent discharge, and reclaimed water per EPA Method 415.3 and China’s GB 3838–2002.
- Research & development: Quantitative assessment of organic load in bioreactor feeds, leachables studies, and cleaning validation swab extracts.
- Academic laboratories: Teaching and method development for carbon cycle analysis, aquatic chemistry, and oxidation kinetics studies.
FAQ
Does the HTY-WOT100 support 21 CFR Part 11 compliance out-of-the-box?
Yes—the system ships with pre-configured electronic signature workflows, audit trail activation, and password-protected access levels. Full validation support packages (including URS, FRS, and test scripts) are available for installation qualification.
Can it analyze high-salinity or seawater samples?
Not directly; samples exceeding 500 mg/L total dissolved solids (TDS) require offline pretreatment (e.g., acidification and sparging) to minimize chloride interference and sensor fouling. A dedicated marine water application note is available upon request.
What maintenance intervals are recommended?
NDIR cell cleaning every 3 months; UV lamp replacement annually or after 8,000 hours; persulfate reagent cartridge replacement every 200 injections. Preventive maintenance logs are auto-generated and included in audit trail exports.
Is remote diagnostics supported?
Yes—via secure TLS-encrypted VNC connection (enabled only upon customer authorization) and optional SNMP-based alerting for pressure, temperature, and flow anomalies.
How is calibration traceability ensured?
Calibration uses NIST-traceable potassium hydrogen phthalate (KHP) and sodium bicarbonate standards. Certificate of Analysis (CoA) with uncertainty budget is supplied with each certified reference material batch.
