Total Nitrogen/Sulfur/Chlorine Analyzer


The TSHR Total Nitrogen/Sulfur Analyzer, model TN/TS 7000, is the most sensitive simultaneous analyzer to detect fast and accurate trace level sulfur and nitrogen concentrations by one single analysis. The analyzer supports a wide range of petrochemical and refinery applications such as liquids and LPG/Gas sample types.

Combined with excellent uptime, matrix independence, exceptional linearity and enhanced performance, the TN/TS 7000 is the ideal solution for both demanding and routine applications.

The TN/TS 7000 model makes use of vertical sample introduction and high temperature oxidation followed by UV-Fluorescence (TS-UVF) and chemiluminescence (TN-CLD) detection.

The TSHR Total Chlorine Analyzer, model TX 7000, is especially designed for customers with a variety of applications and high sample throughput. The design of the analyzer with a vertical positioned furnace tube provides customers a small bench space Total Chlorine analyzer microcoulometric solution with high performance and most accurate results.
