Shuorui Technology Total Organic Carbon Analyzer SR-TOC-01A

The following is a maintenance and upkeep guide for an online total organic carbon analyzer:

1. Daily maintenance

Check the operating status: Regularly check the operation status of the instrument every day, including whether the display screen data is normal, whether there are alarm messages, etc. Ensure that the instrument is in normal working mode and all indicator lights are displaying normally.

Cleaning the casing: Gently wipe the casing of the instrument with a clean soft cloth to remove dust and stains from the surface and keep the appearance of the instrument clean. Be careful to avoid using corrosive cleaning agents to prevent damage to the surface of the instrument.

Check pipeline connections: Carefully inspect the various pipeline connections of the instrument for firmness, looseness, damage, or leakage. Especially for the parts connected to the instrument such as the injection tube and the discharge tube, it is necessary to ensure good sealing to prevent sample or reagent leakage.

Cleaning the sample pool: If the instrument is equipped with a sample pool, it needs to be cleaned regularly. When the instrument stops running, carefully remove the sample tank, rinse it with clean water to remove any remaining samples and impurities in the tank, then dry it with clean gauze and reinstall it.

2. Regular maintenance of online total organic carbon analyzer

Calibration instrument: Regularly calibrate the TOC analyzer according to the operating manual requirements of the instrument. Generally speaking, calibration should be conducted at least once a week to ensure the accuracy of measurement results. During the calibration process, standard solutions should be used and the calibration steps should be strictly followed to record the calibration data and results.

Replace consumables: Regularly replace consumables such as injection needles, filter cartridges, pump tubes, etc. according to the frequency of use of the instrument and the manufacturer's recommendations. These consumables will gradually wear out or become contaminated during use, affecting the performance and measurement results of the instrument. Timely replacement of consumables can ensure the normal operation and measurement accuracy of the instrument.

Cleaning the flow cell: The flow cell is one of the key components of the TOC analyzer and is easily affected by impurities and pollutants in the sample. Regular cleaning of the circulation pool can improve the sensitivity and accuracy of the instrument. When cleaning, an appropriate cleaning solution can be used, and the cleaning operation should be carried out according to the requirements of the instrument's operating manual. Be careful not to damage the internal structure of the flow cell.

Check the electrical system: Check the electrical system of the instrument every month, including whether the power cord, plug, socket, etc. are normal, whether there is any damage or aging. At the same time, check the internal circuit board and electronic components of the instrument to ensure that they are working properly without looseness, overheating, or abnormal noise.

3. Long term maintenance

Deep maintenance: Conduct comprehensive deep maintenance on the instrument at regular intervals (such as six months or one year). This includes lubricating the internal mechanical components of the instrument, cleaning and calibrating the optical system, and testing and evaluating the overall performance of the instrument. Deep maintenance can extend the service life of instruments, improve their reliability and stability.

Storage management: If the instrument is not used for a long time, proper storage management is required. Firstly, empty the samples and reagents inside the instrument and clean all components thoroughly. Then, store the instrument in a dry, ventilated, and non corrosive gas environment, avoiding direct sunlight and moisture. During storage, regularly perform power on checks on the instrument to ensure its performance is not affected.
