Kjeldahl nitrogenizer can achieve colorless and transparent

Shanghai Xinzhuang Instrument Co., Ltd. is a leading manufacturer of high-quality analytical instruments, known for its innovative and environmentally friendly products. The company's flagship product, the Klein Nitrogen Analyzer (LNB), is designed with energy efficiency in mind, offering superior performance and reliability. With a dedicated team of skilled professionals and advanced technology, Xinzhuang ensures top-notch quality and cost-effective solutions for customers worldwide. The Kjeldahl method, which is widely used in nitrogen analysis, involves the digestion of organic compounds with sulfuric acid to convert nitrogen into ammonium sulfate. To enhance the boiling point during this process, potassium sulfate is typically added. After the digestion, a small amount of sodium hydroxide is introduced, causing the solution to change color from dark to clear. This indicates the completion of the reaction, after which ammonia is distilled and captured in boric acid. The total nitrogen content is then determined through back titration, using methyl orange as an indicator and sodium carbonate to neutralize any excess acid. The final result is calculated by multiplying the titration value by a specific conversion factor. The Xinzhuang Nitrogen Analyzer offers a user-friendly interface with one-button operation and multilingual support, making it easy to use for operators of all skill levels. It is equipped with a comprehensive safety system, including optical and acoustic alarms that detect issues such as incorrect placement of the digestion tube, an open safety door, or low reagent levels. These features ensure safe and efficient operation. The instrument also includes a programmable control system, allowing users to customize reaction and distillation times, adjust steam power between 40% and 100%, and choose between automatic or manual addition of sodium hydroxide. With a measurement range of 0.1 to 200 mg, a nitrogen recovery rate of 99.5%, and a repeatability of ±1%, the analyzer delivers precise and consistent results. Additional features include a standby distillation function, an independent cleaning program, and an intuitive design that enhances overall usability. At Shanghai Xinzhuang, we are committed to providing reliable, high-quality solutions that meet the needs of our global customers. Our dedication to innovation, integrity, and customer satisfaction has earned us a strong reputation in the industry. Whether you're looking for precision, ease of use, or long-term value, our products are designed to exceed expectations. Trust in Xinzhuang — where quality meets excellence.
