Installation and Aging of Jena Graphite Tubes in Germany: Pre treatment Steps for Jena Graphite Tubes Before Use
Date: 2026-04-25Read: 1
Jena graphite tube from GermanyIt is the core component used for sample atomization in atomic absorption spectrometers. The standardization of its installation, the rationality of aging treatment, and the quality of pre-treatment before use directly affect the detection accuracy and the service life of graphite tubes. Proper pre-treatment steps before use can effectively remove impurities on the surface of graphite tubes, stabilize their performance, ensure smooth atomization process, and guarantee accurate and reliable detection results.
The pre-treatment of graphite tubes before use requires cleaning treatment. The surface of the new graphite tube may contain impurities and dust generated during the production process. If used directly, it will affect the atomization effect and detection accuracy. When cleaning, special finger cots should be worn to avoid direct contact with the graphite tube by hand and prevent contamination of the graphite tube by grease and sweat on the hands. Special cleaning tools can be used to gently wipe the inner and outer surfaces of the graphite tube to remove surface impurities. After wiping, rinse with clean reagents, air dry and set aside to ensure that the surface of the graphite tube is clean and free of impurities.
Secondly, air burning pretreatment is necessary, which is a key step to ensure the stability of graphite tube performance. Install the cleaned graphite tube correctly into the instrument, close the instrument door, set appropriate air burning parameters according to the instrument operating specifications, and perform air burning treatment. During the air burning process, residual impurities inside the graphite tube can be further removed, while making the temperature distribution of the graphite tube uniform, stabilizing its thermal performance, and avoiding the impact of temperature fluctuations on the atomization effect during formal testing. The number and duration of empty burning must comply with relevant requirements until the empty burning value reaches the specified standard, ensuring that the graphite tube can function normally.
During the preprocessing process, it is also necessary to checkJena graphite tube from GermanyThe installation status. During installation, it is necessary to ensure that the graphite tube is aligned with the graphite cone and has good contact to avoid installation deviation that may cause an increase in resistance and accelerate the aging of the graphite tube. At the same time, check the appearance of the graphite tube to confirm that there are no defects such as damage or cracks. If there are any abnormalities, replace the graphite tube with a new one. After the preprocessing is completed, the instrument needs to be debugged briefly to confirm that the graphite tube is running normally without any abnormal heating, noise, or other conditions before proceeding with the subsequent sample testing work. Standardized preprocessing steps can effectively extend the service life of graphite tubes and improve detection accuracy.
