It is simple and efficient to use, requiring only a sample boat or quartz carrier in conjunction with an ion chromatograph or microcoulometer to obtain experimental results.

Detailed Information:

Application Areas:

Drinking water, surface water, groundwater, sewage, effluent, wastewater, tap water, saline water, treated water, pulp effluent, soil, sediment, sludge, and waste oil

AOX Analysis Principle

Using the column adsorption method, activated carbon is employed to adsorb organic halogens in water. After high-temperature combustion, the sample enters a bubble absorption tube, and data is read on an ion chromatograph or microcoulometer.

AOX-C Combustion Furnace

The AOX-C Combustion Furnace features a ceramic fiber inner liner for energy efficiency and high performance. It consists of two semi-circular furnace liners embedded with high-temperature resistance wires, combined to form the furnace. The high-temperature resistance wires generate heat, with air cooling and a metal outer shell. The AOX combustion furnace is characterized by fast heating speed, an openable furnace body function, and rapid cooling.

The control system uses an LTDE programmable instrument with adjustable heating rates. The PID + SSR system ensures synchronous and coordinated control, enabling consistency and reproducibility in any test or experiment. It features automatic temperature control and time control functions, with secondary over-temperature protection for reliable control and safe use. It is specifically designed for rapid and accurate analysis of various liquid and solid samples, making it an ideal instrument for organic halogen analysis in laboratories. It fully complies with the testing standard "Standard (HJ/T83-2001) Water Quality—Determination of Adsorbable Organic Halogens (AOX)," particularly suitable for laboratories requiring continuous analysis throughout the day. It is simple and efficient to use.
