Diffusion hydrogen analyzer is a special detection instrument used to detect hydrogen content in materials, widely used in the following fields:

Welding industry:

During the welding process, the presence of hydrogen may cause hydrogen embrittlement or hydrogen induced cracking in the weld seam, seriously affecting the welding quality. The diffusion hydrogen analyzer can accurately measure the diffusion hydrogen content in welding materials and welds, helping to optimize welding processes and avoid quality problems caused by hydrogen embrittlement.

Material research and development:

In the field of materials science, diffusion hydrogen analyzers are used to evaluate the diffusion behavior of different materials in hydrogen environments, study fundamental issues such as hydrogen diffusion mechanisms and hydrogen permeation rates, and provide key data support for the development of new materials.

Hydrogen energy technology:

In the field of hydrogen energy, diffusion hydrogen analyzer is used to evaluate the hydrogen permeation performance of key components such as fuel cells and hydrogen storage materials, ensuring the safety and efficiency of hydrogen energy systems.

Industrial material quality control:

The control of hydrogen content is crucial for the performance of special industrial materials such as aviation materials, oil pipelines, and chemical equipment. The diffusion hydrogen analyzer can monitor the hydrogen content of materials to prevent material failure caused by hydrogen diffusion.

Steps for using a diffusion hydrogen analyzer

Taking the glycerol diffusion hydrogen analyzer as an example, its usage steps are as follows:

Experimental preparation:

Determine the experimental plan: Select the appropriate testing method based on the testing requirements.

Preparation of samples: Pre treat the samples to ensure a smooth and clean surface.

Check the instrument: Confirm that all components of the instrument are connected properly, the carrier gas pressure meets the standard, and the cooling water system is turned on.

Prepare gas: Prepare the required gas according to the testing method.

Sample loading:

Place the test sample into a quartz sample tube and ensure that the tube is well sealed.

For the glycerol method, the sample needs to be immersed in glycerol and covered with a gas collector.

Calibration instrument:

Use the built-in calibration unit for calibration, using standard gases or certified mixtures as calibration gases to ensure instrument accuracy.

Set testing conditions:

Set measurement parameters through the operation interface, including temperature, pressure, hydrogen flow rate, etc.

Start measurement:

Start the measurement program, and the instrument automatically completes sample heating, hydrogen extraction, and detection.

During the heating process, hydrogen atoms diffuse outward from the inside of the sample, and the instrument calculates the hydrogen content in the material by detecting the amount of hydrogen gas released.

Data recording and analysis:

After the measurement is completed, the instrument generates a data report that meets international standards.

Users can save, print data, or conduct further analysis through network transmission.

Calculate the diffusion hydrogen content based on the data.

Subsequent processing:

Clean the surface of the instrument, infrared furnace, tube furnace, and quartz sample tube to remove dust and dirt.

Regularly inspect heating elements, detectors, connecting pipelines, and other components to ensure no damage or aging.

Establish maintenance logs to record the time, content, and issues discovered during each maintenance.
