There are several types of automatic nitrogen analyzers, and they are distinguished mainly by the technique used to measure nitrogen content. These types include the following:
Kjeldahl Nitrogen Analyzer
This device measures total nitrogen by digesting a sample in acid and recording ammonia. The amount of ammonia indicates total nitrogen concentration. Automatic Kjeldahl nitrogen analyzers accelerate the process to improve efficiency. These tools are widely used in the food and agricultural industries since they measure total nitrogen in protein content.
Leco Nitrogren Analyzer
Users hold the nitrogen analyzer from Leco in high regard. The company’s analytical instruments have served for decades, in particular, the nitrogen analyzer. This device utilizes a method of combustion in pure oxygen to record the amount of nitrogen that is gas released. The exclusive aspect of this nitrogen analyzer is that it combines speed with accuracy. It is a favorite in industries such as metal, chemical, and coal, where quick and precise nitrogen content analysis is required.
Auto-Catalytic Nitrogen Analyzer
Users of the Auto-Catalytic Nitrogen Analyzer heat their samples while in a flow of oxygen. This releases nitrogen that is available from the sample. A catalyst that is employed in this analyzer speeds up the reaction, making the process more effective. For this reason, it is often used in petrochemical and refining processes where fast results are essential.
Chromatographic Nitrogen Analyzer
The chromatographic nitrogen analyzer works by separating gases including nitrogen and measuring it using gas chromatography. This analyzer can also be used to evaluate and simultaneously measure trace amounts of nitrogen in several atmospheric gases.
Infrared Nitrogen Detector
Infrared Nitrogen Detectors work by identifying nitrogen gas based on the absorption of infrared light. This is a non-destructive approach. This detector is useful in the monitoring and analysis of emissions, particularly in the field of environmental analysis.
Chemical Industry
Nitrogen is a crucial measurement in chemicals such as fertilizers and explosives. Automatic nitrogen analyzers are useful in quickly and accurately measuring nitrogen content in raw materials and finished products. These guarantees quality control and product compliance with regulations.
Pharmaceutical Industry

These helps to make certain adherence to strict regulatory standards.
Food and Beverage Industry
Users conduct nitrogen analysis in the food and beverage industry to measure protein content in foods and essential nutrients like amino acids in dietary supplements. They also evaluate the quantity of protein in animal feeds. Automatic nitrogen analyzers are used to determine the protein content in food. These are faster and more accurate than the traditional Kjeldahl method.
Agriculture Industry
Users conduct nitrogen analysis in the agricultural sector to improve crop yields. Automatic nitrogen analyzers are useful in measuring nitrogen content in soils and fertilizers. These helps farmers to make informed decisions on fertilizer application and soil amendment. This consequently optimizes growth and productivity of the crops.
Petroleum and Petrochemical Industry
In petroleum and petrochemical industries, nitrogen content analysis in crude oil and natural gas is vital in quality control and process optimization. Automatic nitrogen analyzers are used to measure nitrogen concentration. These gives result faster and more accurately than older methods.
Environmental Monitoring
Scientists in their quest to improve environmental conditions employ automatic nitrogen analyzers to measure nitrogen levels in water and air. These levels usually increase due to industrial activities. The increase promtes pollution and the degradation of ecosystems. Automatic nitrogen analyzers help give accurate and timely data for environmental monitoring and management.
When looking for an automatic nitrogen analyzer suitable for industrial needs, buyers have to consider the following:
Method of Analysis
Automatic nitrogen analyzers use various methods to analyze nitrogen content. They include the Kjeldahl method, combustion method, and the infrared absorption method. Each method suits specific industries and requirements. Users should choose the method that is most appropriate for their application. For instance, the Kjeldahl method for food and agriculture, while the combustion method for quick analysis in industrial settings.
Accuracy and Precision
Accuracy and precision are crucial to analyzers since they affect product quality and compliance with the regulations. Therefore, users should ensure that the nitrogen analyzer they are settling for meets the required standards for their industry. It is important to look for devices that have been verified for accuracy and go for those with the least margin of error.
Sample Types and Sizes
Automatic nitrogen analyzers are designed to work with specific sample types and sizes. Therefore, users should choose analyzers that handle the types of samples they are dealing with. For instance, samples in the food industry may be complex matrices that require digestion before analysis. On the other hand, a sample in the chemical industry may be pure substances that need simpler analytical methods.
Throughput and Speed
In industries where large volumes of samples are analyzed, the throughput and speed of the nitrogen analyzer are important considerations. In such scenarios, users should look for high-throughput analyzers that can analyze large numbers of samples in the shortest time possible. High throughput ensures efficiency in testing and reducing bottlenecks in the operations.
Ease of Use and Automation
Modern nitrogenn analyzers are designed with ease of use in mind. Many of them incorporate automated features that reduce the need for manual intervention, which is a good thing. Automation comes with advantages. For instance, it minimizes human errors. It also reduces labor costs.
Maintenance and Calibration
It is worth noting that even the most sophisticated instruments ever made require maintenance and calibration to ensure continuous accurate performance. Industries should consider the maintenance requirements of the nitrogen analyzer they want to purchase. In particular, how frequently they will need to be serviced and whether the manufacturer's support is readily available in case of problems.
Cost and Budget
Cost can be a determining factor when purchasing an automatic nitrogen gas analyzer. Various automatic analyzers are available in the market with different price tags as well as numerous budget considerations. Buying one of them does not need to cause a financial strain. A cost-effective approach helps keep the overall production costs down as well as provides good returns on investment.
Here are some important product specifications and maintenance practices to consider:
Key Features
Automatic nitrogen analyzers usually incorporate a number of key features. They include:
Electrical Requirements
Automatic nitrogen analyzers come with different electrical requirements. Knowing these requirements helps with proper installation and operation. Most automatic nitrogen analyzers normally work with standard electrical outlets. Some may require dedicated circuits for optimal performance.
Installation
Proper installation of automatic nitrogen analyzers is key to ensuring their effectiveness and accuracy. As mentioned before, each analyzer has its own specific requirements for installation. Therefore, users should carefully follow the manufacturer’s installation guidelines. They should also ensure that the analyzer is placed in a stable environment with minimal vibrations and extreme variations in temperatures.
Calibration
It is important to ensure that automatic nitrogen analyzers deliver accurate results. Most nitrogen analyzers provide manufacturers' recommended calibration frequencies. Regular calibration usually helps maintain accuracy over time and ensures compliance with industry standards. It also reduces the likelihood of obtaining erroneous results, which can be costly in terms of time and resources to rectify. Thus, users should adhere to the calibration schedule provided by the manufacturer.
