The AOX-WK-3 Halogen Analyzer is specifically 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 Papers" and "GB/T 22904-2008 Pulp, Paper, and Board—Determination of Total Chlorine and Organic Chlorine." It features high cost-effectiveness, ease of use, and efficiency. The AOX-WK-3 Halogen Analyzer includes an AOX combustion furnace, offering lower costs and simpler, more efficient operation compared to ion chromatographs. It serves as an ideal alternative to imported halogen analyzers for AOX determination.

Application Areas:

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

The AOX-WK-3 Halogen Analyzer operates on the Windows platform, featuring a user-friendly interface that enables analysts to perform operations more conveniently and quickly. 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: For purchases of the "AOX-WK-3 Halogen Analyzer" produced by our company, we provide installation and operational reference materials with illustrations, along with one on-site installation and calibration service.
