main features

Gas liquid separation:Advanced cold trap technology, using polytetrafluoroethylene material as the reaction tube,Make gas-liquid separation more thorough, without the need for any desiccant;

■Equipped with a water removal system, no desiccant is used during the entire analysis process;

■Equipped with an electronic pressure alarm system: in case of changes in carrier gas flow rate and pressure, orFault in the carrier gas system, automatic buzzer alarm and automatic shutdown of the injection and heating system, same asLock the software in real-time;

■ Automatic sampler:60Number of sample positions above, sample volume50ml；

■ Blow homogenization system： （Sample mixing device），Inject gas and stir, automatically remove get rid ofVOCWaiting for interference;

■When measuring ammonia nitrogen, Only one sample is taken, and the sample can be measured simultaneouslyAmmonia nitrogen and nitrite in the product Nitrate nitrogen content;

■Equipped with an integrated module for total nitrogen UV online digestion and dilution: achieving continuous self purification of total nitrogen Dynamic online digestion, with online dilution function and automatic configuration of standard curve;

■Having nitrate nitrogen/Automatic cleaning function during total nitrogen testing process;
