Sievers M9 TOC Analyzer

The Sievers M9 TOC Analyzer is a high-performance Total Organic Carbon (TOC) analysis instrument developed by Sievers, a brand under Veolia. Designed specifically for water quality monitoring, it delivers exceptional analytical performance, flexible configuration options, and broad industry applicability, making it a reliable tool for pharmaceutical, microelectronics, power generation, and environmental protection sectors in water quality control and cleaning validation.

🧪 Core Technology & Performance

The Sievers M9 TOC Analyzer utilizes a combination of ultraviolet (UV)/persulfate oxidation and membrane conductivity detection technology. Its workflow is as follows:

1. Oxidation: UV light and persulfate completely oxidize organic matter in the sample into carbon dioxide (CO₂), which reacts with water to form carbonic acid (H₂CO₃).

2. Detection: A high-sensitivity membrane conductivity cell measures the change in conductivity before and after oxidation to accurately calculate the TOC value.

This technology effectively avoids interference from impurity ions, ensuring superior accuracy and precision.

Key performance specifications:

• Wide dynamic detection range: 0.03 ppb to 50 ppm

• Accuracy: ±2% or ±0.5 ppb (whichever is greater)

• Precision (repeatability): <1% RSD

⚡ Efficiency & Intelligent Operation

The Sievers M9 TOC Analyzer delivers fast analysis speeds:

• Standard mode: ~2 minutes per analysis

• Optional Turbo mode: Reduces analysis time to just 4 seconds, ideal for real-time monitoring and rapid feedback in online applications (e.g., recycled water monitoring).

The instrument features multiple automation functions to enhance efficiency and minimize human error, including:

• Automatic calibration, validation, and data analysis

• Automatic reagent adjustment (optimizes flow rate for each sample)

• Method storage and streamlined operation protocols

Additionally, it requires minimal maintenance—typically only a few hours of preventive maintenance per year—and has a 12-month calibration stability period, significantly reducing long-term operational costs.

🧰 Flexible Configurations & Applications

The Sievers M9 TOC Analyzer is available in three main models to suit different application scenarios:

1. Laboratory Model (Lab)

   • Ideal for batch sample testing in labs

   • Compatible with autosamplers (up to 120 sample positions)

   • Compact design (24.6 cm width) saves bench space

2. Online Model (On-Line)

   • Designed for continuous water system monitoring

   • Wall-mountable with IP-45 protection rating (suitable for harsh environments)

   • Dimensions: 54.9 cm (H) × 45.0 cm (W) × 26.5 cm (D)

   • Weight: 15.8 kg

3. Portable Model (Portable)

   • Lightweight (9.4 kg) and compact (39.5 cm H × 22.9 cm W × 46.4 cm D)

   • IP-21 protection rating

   • Easily transportable for on-site testing and troubleshooting

Additionally, the Lab and Portable models offer an optional feature—simultaneous conductivity detection, allowing users to measure both TOC and Stage 1 conductivity in a single analysis. This simplifies compliance testing for pharmaceutical water per pharmacopeia requirements.
