Total Organic Carbon Analyzer

I. Product Overview

Based on differential conductivity detection technology, this instrument is designed for TOC determination in high-purity water systems. It provides accurate TOC analysis and meets the requirements of the pharmacopoeia and related industry regulations, and can be widely used for water quality testing in the pharmaceutical, microelectronics and power industries.

II. Measuring Principle

The instrument is based on the differential conductivity method and photochemical oxidation technology. Water samples are irradiated with UV light of a specific wavelength, ultimately converting organic molecules in the water into carbonic acid, which causes a significant change in the conductivity of the sample. An internal algorithm model converts this change into the total organic carbon (TOC) content of the sample.

IV. Applications

Pharmaceutical industry: on-line monitoring and cleaning validation of purified water and water for injection (WFI), meeting pharmacopoeia requirements.
Microelectronics / semiconductor industry: ultrapure water quality monitoring.
Power industry: water quality control in nuclear power and ultra-high-pressure boiler make-up water systems.
Research laboratories: routine water quality analysis.

V. Key Features

1. Android 10 system with a 7-inch colour touch screen for integrated operation.

2. Dual-wavelength UV lamp for thorough oxidation of organic matter, with a stable oxidation efficiency above 99 %.

3. Differential conductivity detection system and proprietary signal processing algorithm with automatic temperature compensation, real-time baseline correction and background subtraction: high sensitivity and effective elimination of interference from common inorganic carbon (IC) and ions in water.

4. Three detection modes — single offline measurement, continuous online monitoring and timed intervals; a single measurement takes less than 12 min.

5. One-key maintenance with integrated cleaning, calibration and self-diagnostics, plus abnormal-status warnings.

6. Long-life core components and very low operating cost: annual operating cost is more than 60 % lower than with the traditional combustion method.

7. Three-level user permission management (administrator, operator, observer) and a complete audit trail, complying with GLP/GMP laboratory quality management requirements.

8. Built-in high-speed thermal printer for immediate printing of results, sample information and QR codes; data can also be uploaded by Wi-Fi to an enterprise LIMS or a dedicated cloud platform.

9. USB export in PDF, CSV and Excel formats.

10. The instrument can be upgraded remotely via the cloud.
