TRN1500 fully automatic soil nitrogen analyzer Introduction: The TRN1500 fully automatic soil nitrogen analyzer is independently developed by Shanghai Beiyu Analytical Instrument Co., Ltd., dedicated to the determination of ammonia nitrogen, nitrite nitrogen, and nitrate nitrogen in soil. It integrates online extraction and testing functions of soil samples as a fully automatic integrated instrument. working principle: According to HJ_634-2012 Soil Determination of Ammonia Nitrogen, Nitrite Nitrogen, and Nitrate Nitrogen - Potassium Chloride Solution Extraction - Spectrometric Method, soil samples were extracted with potassium chloride solution, and the extracted clear solution was determined using gas phase molecular absorption spectroscopy. One extraction supports the simultaneous determination of three items: ammonia nitrogen, nitrite nitrogen, and nitrate nitrogen, without the need for separate measurements based on different items; Instrument features: 1. Accurate control of a 20 ℃ constant temperature water bath, with a temperature error of less than 0.3 ℃, ensuring extraction efficiency; 2. Automatic intelligent variable speed magnetic stirring, making the sample and extraction liquid mix more evenly; 3. There is no need to replace the container throughout the entire process to avoid container contamination; 4. The entire process of extraction, precipitation, and other measurements is automated, without the need for manual operation; 5. Support up to 30 sample measurements; 6. High concentration samples can be diluted and measured online. 7. Detection limit: Ammonia nitrogen 0.10mg/Kg Nitrite nitrogen 0.10 mg/Kg Nitrate nitrogen 0.20 mg/Kg
