The HTTNS-3000 Sulfur and Nitrogen Analyzer uses the ultraviolet fluorescence method to determine total sulfur content and the chemiluminescence method to determine nitrogen content. This enhances its ability to resist impurity interference, avoids the cumbersome operation of the titration cell in the coulometric method and the resulting unstable factors, and greatly improves the sensitivity of the instrument. Key components of the system adopt imported devices, ensuring reliable overall performance of the instrument. Application fields: environmental protection, chemical industry, biological industry, petroleum, energy.
