Looking for a TOC analyzer with international certifications? ERUN’s total organic carbon analyzers are CE, ISO 9001, and RoHS certified, delivering 1 ppb detection limits for pharmaceutical water, ultrapure water, and industrial wastewater applications—backed by 16 patents and a 4,500 m² manufacturing facility.
1. What Is a TOC Analyzer and Why Do You Need One?
A TOC analyzer (total organic carbon analyzer) is an instrument that measures the total amount of organic carbon in water samples. Organic carbon indicates contamination from industrial discharge, pharmaceutical residues, or natural organic matter. Regulatory standards such as USP 643, EP 2.2.44, and EPA methods require TOC monitoring for pharmaceutical water, drinking water, and wastewater discharge.
ERUN’s TOC analyzers simultaneously measure total carbon (TC), total inorganic carbon (TIC), total organic carbon (TOC), and non-purgeable organic carbon (NPOC) in a single run.
2. Certified Quality: CE, ISO 9001, and RoHS Compliance
ERUN’s TOC analyzers hold CE, ISO 9001, and RoHS certifications—essential for exporting to EU and global markets. CE certification confirms compliance with EU safety, health, and environmental protection requirements. ISO 9001 ensures consistent manufacturing quality. RoHS certification guarantees the absence of restricted hazardous substances.
Beyond these three core certifications, ERUN has also obtained ISO 14001 (environmental management), ISO 45001 (occupational health and safety), SIL4 certification, and UN38.3 transport safety reports for air and sea freight. With 16 patents, 18 software copyrights, and 42 trademarks, ERUN is recognized as a high-tech enterprise and technology-focused SME.
3. Precision Technology: UV Persulfate Oxidation + NDIR Detection
ERUN TOC analyzers use UV persulfate oxidation combined with non-dispersive infrared (NDIR) detection for accurate organic carbon measurement. One sample is oxidized with UV and persulfate to convert organic carbon to CO₂; another is acidified to convert inorganic carbon to CO₂. Both CO₂ streams are dehydrated and measured by the NDIR detector.
This dual-channel approach ensures precise differentiation between TOC and TIC. The portable ERUN-SP3-J3 achieves a detection limit of 1 ppb (0.1 μg/L) with a range of 0.1–1000 μg/L—ideal for ultrapure water and pharmaceutical applications. The laboratory ERUN-ST3-J3 covers 0–30,000 mg/L with automatic dilution for high-concentration samples.
4. Industry Applications
ERUN TOC analyzers serve pharmaceutical, electronics, power generation, environmental, and industrial sectors. Key applications include:
Pharmaceutical: Purified water, water for injection (WFI), and cleaning validation per USP 643 and EP 2.2.44
Electronics: Ultrapure water for semiconductor manufacturing
Power generation: Boiler water, condensate water, and cooling water
Environmental: Surface water, groundwater, seawater, domestic sewage, and industrial wastewater
Laboratory: Drinking water quality testing and research
The ERUN-SP3-J3 completes a single test in under 3 minutes with a 24-position auto-sampler for unattended operation.

8. Frequently Asked Questions
Q: What is the difference between TOC, TC, TIC, and NPOC?
A: TC is total carbon. TIC is inorganic carbon (carbonates). TOC = TC − TIC. NPOC is organic carbon remaining after purging, measured when volatile organics are removed.
Q: What detection methods does ERUN offer?
A: UV persulfate oxidation (portable and select online models) and high-temperature catalytic oxidation (laboratory models).
Q: Which industries need TOC analysis?
A: Pharmaceutical, electronics, power generation, environmental monitoring, food and beverage, and chemical processing.
Q: Is ERUN a manufacturer or a trading company?
A: ERUN is a direct manufacturer with in-house R&D, production, and quality control—not a trading company.
Q: What is the minimum order quantity?
A: Contact ERUN directly for MOQ and pricing based on your specific configuration needs.
