Total Organic Carbon (TOC) Analysis

 

Carbon-centric precision for comprehensive monitoring of organic contaminants.
 

Total Organic Carbon (TOC) provides a direct measurement of the carbon content within organic molecules in a water sample. At Weshin Inspection Tech , we utilize state-of-the-art combustion and UV-oxidation technologies to deliver high-resolution TOC analysis, ranging from parts-per-billion (ppb) levels in ultrapure water to high-load industrial effluents.

 

The Critical Importance of TOC Monitoring

 

TOC is recognized as the most reliable indicator for modern water quality management:
 

  • Ultrapure Water (UPW) Integrity: In semiconductor and display manufacturing, TOC levels are critical to yield; we provide the sensitivity needed to monitor UPW loops.

  • Rapid Environmental Screening: Offering faster results than BOD (5 days) or COD (2 hours), TOC is ideal for real-time process control and early spill detection.

  • Pharmaceutical Compliance: Meeting the stringent TOC requirements (typically < 500 ppb) set by USP, EP, and JP for Purified Water and Water for Injection (WFI).

  • Industrial Wastewater Management: Quantifying the total organic load to evaluate the performance of oxidation and carbon adsorption treatments.
     

Our Analytical Capabilities

 

Weshin Inspection Tech employs advanced automation to ensure reproducible data:

  • High-Temperature Catalytic Combustion: Optimized for complex matrices and industrial wastewater containing particulates or salts.

  • UV-Persulfate Oxidation: Delivering superior precision and sensitivity for low-concentration samples and high-purity water systems.

  • Non-Purgeable Organic Carbon (NPOC) Analysis: Effectively removing Inorganic Carbon (IC) interferences through automated acidification and sparging.
