Pulse melting thermal conductivity nitrogen analyzer

Pulse melting thermal conductivity nitrogen analyzerIt is an instrument used to determine the nitrogen content in a sample. It uses pulse heating technology to quickly heat the sample to a high temperature state, and then measures the nitrogen content in the sample through the principle of thermal conduction. This instrument has the advantages of high sensitivity, good accuracy, and easy operation, and is widely used in metallurgy, chemical engineering, building materials, and other fields.

The working principle is to use the thermal conductivity characteristics of the sample at high temperatures to determine its nitrogen content. Specifically, when the sample is heated to a high temperature, the nitrogen inside will react with oxygen to form nitrogen oxides, which will recombine into nitrogen gas as the sample cools. Due to the low thermal conductivity of nitrogen, the nitrogen content can be determined by measuring the thermal conductivity of the sample at different temperatures.

It mainly consists of the following parts:

Heating system: including heating elements, heating chambers, and other parts, used to heat the sample to a high temperature state.

Control system: including temperature controller, timer, etc., used to control heating time and temperature.

Sensor system: including thermocouples, thermistors, and other components, used to measure the thermal conductivity of samples at different temperatures.

Data processing system: including data acquisition card, computer and other parts, used for processing and analyzing measurement data.

Operation steps

Preparation of samples: Grind and mix the test sample according to the requirements to achieve a certain particle size and uniformity.

Installation of samples: Place the processed samples into the sample tray and seal and secure them as required.

Set parameters: Set heating temperature, time, and other parameters as needed, and start the control system.

Start testing: When the sample reaches the set temperature, begin measuring the thermal conductivity.

Data processing: Input the measured data into the data processing system for calculation and analysis, and obtain the nitrogen content in the sample.

Result output: Output the analysis results to a monitor or printer for users to view and save.

Pulse melting thermal conductivity nitrogen analyzerWidely used in metallurgy, chemical industry, building materials and other fields, mainly used in the following areas:

Metallurgical industry: used to determine the nitrogen content in metal materials such as steel and aluminum to evaluate their quality and performance.

Chemical industry: used to determine the nitrogen content in chemical products such as fertilizers and synthetic resins to evaluate their purity and quality.

Building materials industry: used to determine the nitrogen content in building materials such as cement and concrete to evaluate their strength and durability.

In the field of environmental protection, it is used to measure the nitrogen content in the atmosphere, water bodies, and other environments to evaluate their pollution level and treatment effectiveness.

Food industry: used to determine the nitrogen content in food to evaluate its nutritional value and safety.
