Shimadzu TOC-L Analyzer + ASI-L Autosampler (Refurbished)

The Shimadzu TOC-L series is a high-performance Total Organic Carbon (TOC) Analyzer designed for precise and reliable carbon analysis in various water samples, ranging from ultrapure water to highly contaminated water. Utilizing the 680°C combustion catalytic oxidation method with NDIR detection, it offers a wide measurement range and high sensitivity, making it suitable for industries including pharmaceuticals, environmental monitoring, food & beverage, and water treatment facilities.

The ASI-L Autosampler complements the TOC-L by enabling automated, high-throughput sample analysis. It supports various vial capacities and provides efficient sample handling with features such as magnetic stirring to prevent sedimentation. This integration ensures streamlined workflow and enhanced analytical accuracy.

The system provides compatibility with additional units such as the TNM-L for Total Nitrogen (TN) measurement and the SSM-5000A for solid sample combustion analysis, enhancing its versatility.
