XHP-01 Automatic Kjeldahl Nitrogen Analyzer

Kjeldahl method is a classical method to determine nitrogen content in soil, food, livestock, agricultural products, feed and other nitrogen-containing compounds. Using this method to determine samples involves a three-step approach: Digestion, distillation and titration.

Kjeldahl nitrogen analyzer is the product with the largest sample quantity (40 positions), the highest degree of automation (no need to transfer tubes manually), can equip with supporting equipment (optional 40-hole digestion furnace).

★ Automatic sample injection system can be placed with 40 digestive tube racks at the same time to meet the requirements of automatic batch analysis.

★ The rectangular design for sample storage allows the sample to be loaded directly onto the machine after digestion together with the digestive tube racks, convenient and fast. Compared with round sample storage plates, the digestive tubes do not have to be transferred for the second time.

★ There are two modes for automatic injection: "Continuous injection" and "individual injection”.

★ Reagent drum equipped with liquid level sensor is disposed in the sample injection system to make the workplace cleaner.

★ One-click button for 1-40 samples: Automatic injection, automatic operation of cooling system, automatic distillation, automatic calculation of blank value, automatic analysis, automatic deduction of blank value, data storage, automatic sample replacement, etc.

★ The main control system adopt 10 inch color touch screen, which can be used to control the " host, sample injection system and cooling system" without using multi-socket, convenient, simple and safe.

★ Three-level authority management, electronic records, electronic tags and traceability system meet relevant certification requirements.

★ The system automatically shuts down when left unattended for 60 minutes, energy-saving and safe.

★ Automatic statistics, calculation, import and deduction of 0-6 blank values, easy to operate. It is perfect "automatic analysis".

★ The instrument has a built-in protein coefficient query table for users to access, query and for system calculation. When the coefficient = 1, the analysis result is" nitrogen content". When the coefficient>1, the analysis result is automatically converted to" protein content". The results can be displayed, stored and printed.

★ The titration system uses R,G,B coaxial light sources and sensors with wide range of colors and high accuracy.

★ Automatic RGB light intensity adjustment system can be used for analysis of boric acid solutions with different formulas and samples with different concentrations.

★ Titration speed can be set freely from 0.05ml/s to 1.0ml/s and the minimum titration volume can reach 0.2ul/step.

★ Germany ILS 10mL and 25mL syringes and 0.6mm linear motor form the high-precision titration system.

★ The titration solution concentration is calibrated internally to eliminate systematic errors, highly accurate and convenient.

★ Titration cups are exposedly loaded for easy observation of the titration process and cleaning.

★ Titration while distillation mode can save analysis time and reduce power consumption by ineffective distillation.

★  Distillation time can be set freely from10s to 9990s.

★ Steam flow can be adjusted freely from 1%-100% for samples with different concentrations.

★ Waste liquid is automatically discharged from the digestive tubes to reduce work intensity of operators.

★ Alkaline lines are automatically cleaned to prevent blockage and ensure liquid supply accuracy.

★ Up to 1 million data can be saved for users to consult.

★ 5.7 cm thermal printer with automatic paper cutting function.

★The standard cooling system saves a large amount of water. It is energy-saving and environmental-friendly.

★ Unique "automatic upload of sample weighing data to the data package", no need to record one by one,  thus reduce input errors and improve work efficiency.

★ The steam system is made of 304 stainless steel, safe and reliable.

★ The cooler is made of 304 stainless steel for fast cooling and stable analysis data.

★  Current Leakage protection system ensures the safety of operators.

★  Safety door and alarm system ensure personal safety.

★  Digestive tube protection system prevents reagents and steam from hurting people.

★  Water shortage alarm of the steam system warns the operator to stop the instrument to prevent accidents.

★ Over-temperature alarm of the steam boiler warns the operator to stop the instrument to prevent accidents.

★ Steam over-pressure alarm warns the operator to stop the instrument to prevent accidents.

★ Sample over-temperature alarm warns the operator to stop the instrument to prevent sample temperature rising from affecting analysis data.

★ Low liquid level alarm of reagent drum and titration bottle.

★ Cooling water flow monitoring system prevents sample loss caused by insufficient water flow to affect analysis results.

★ The system does not work if the injection system door is not opened to prevent the digestive tube rack from moving out to hit the door.

★ Double-station detection of digestive tubes to prevent instrument damage caused by stuck.

★ Automatic 1-40-hole sample injection system can be placed with 2*20-hole digestive tube rack.

★ The rectangular design for sample storage allows the sample to be loaded directly onto the machine after digestion together with the digestive tube racks, convenient and fast. Compared with sample storage plates, the digestive tubes do not have to be transferred for the second time.

★The steam system is made of 304 stainless steel, safe and reliable.

★The cooler is made of 304 stainless steel for fast cooling and stable analysis data.
