In addition to the correct operation and the use of fully automatic Kjeldahl instrument, the maintenance of the instrument is also essential. For the maintenance of the automatic Kjeldahl instrument, in addition to daily maintenance, it also needs to be changed every week. With the need to do weekly maintenance work, let's briefly introduce the weekly maintenance method of the automatic Kjeldahl nitrogen analyzer.
The weekly maintenance of the automatic Kjeldahl instrument is divided into four major steps, the main content is inspection and cleaning, the detailed maintenance methods are as follows:
1. Check and clean the reagent tank. Check the reagent barrel for any residue. If necessary, clean it in time. Check the solution barrel for cracks. If there is any damage, replace it and check if there is any reagent crystallized to block the air hole of the lid. Clean the lid with warm water and check if the detector is normal. If it is damaged, it can be replaced properly.
2. Thoroughly clean the alkali pipeline To prevent the alkali crystallization from affecting the life of the alkali pipeline of the instrument, it is necessary to flush the alkali pipeline every week.
3. Cleaning the Boric Acid Pipeline To prevent the magazine in the boric acid from clogging the boric acid valve and pump, the boric acid pipeline should be cleaned weekly.
4. Clean the titration acid line and the syringe pump. Clean the residue in the syringe pump and titration acid line.
5, check the digestive tract Check the edge of the mouth of the digestive tube for cracks and cracks, to avoid leakage due to such damage caused by the digestive tube and the distillation head, resulting in loss of sample recovery. Check the bottom of the joke tube for cracks and cracks to avoid the bursting of the digestive tube distillation process, resulting in a great safety hazard.
The above is the introduction of the weekly maintenance method of the automatic Kjeldahl nitrogen analyzer. To ensure the good performance of the instrument and prolong the service life of the instrument, and to ensure safe and efficient use, it is necessary to do the maintenance work, the above fully automatic Kjelda The weekly maintenance method of the nitrogen meter is for your reference. I hope that it will be helpful for everyone to operate the instrument.
