The AOX-WK-3 Halogen Analyzer is a specialized instrument designed for the rapid and precise detection of organic halogens in various household papers. It complies with the standards "GB/T 34845-2017 Determination of Adsorbable Organic Halogens (AOX) in Household Paper" and "GB/T 22904-2008 Pulp, Paper, and Board—Determination of Total Chlorine and Organic Chlorine." It offers high cost-effectiveness, ease of use, and efficiency. The AOX-WK-3 Halogen Analyzer includes an AOX combustion furnace. Compared to ion chromatographs, it has lower costs, is user-friendly, and highly efficient. It can serve as an ideal replacement for imported halogen analyzers and is an excellent instrument for AOX determination.

Application Areas:

Determination of AOX in various papers produced from wood fiber or non-wood fiber raw materials, including toilet paper, tissue paper (paper napkins, paper towels, paper handkerchiefs), hand towels, kitchen towels, crepe paper, and other household papers, as well as various pulps, paper, and paperboard.

The AOX-WK-3 Halogen Analyzer operates on the Windows operating system, featuring a user-friendly interface that makes it more convenient and efficient for analysts. During system analysis, operating conditions, analytical parameters, and results are displayed directly on the screen. Parameters and results can be saved and printed as needed for future reference and archiving.

Note: When purchasing the "AOX-WK-3 Halogen Analyzer" from our company, we provide installation and operational graphic reference materials, along with one on-site installation and calibration service.
