What to do when the water quality analyzer is contaminated by external pollution, in fact, we can deal with it in a timely and correct manner, which is the key to ensure the accuracy and performance of the instrument. Here are some common ways to deal with external contamination:
1. Clean the surface of the instrument
Use an appropriate detergent and soft cloth to clean the instrument surfaces, including the instrument housing, operator panel, and display. Make sure the instrument is turned off and cleaned according to the recommendations.
2. Clean the optical components
If the instrument uses optical components such as light sources, detectors, lenses, etc., ensure that these elements are kept clean. Use specialized cleaning tools or follow the manufacturer's recommendations.
3. Protective measures:
Place protective measures around the instrument, such as a clear hood or shield, to prevent liquids, particles, or other contaminants from entering the instrument.
4. Avoid direct sunlight
Avoid exposing the instrument to direct sunlight, as sunlight may cause overheating or light and shadow on the surface of the instrument, affecting the accuracy of the measurement.
5. Avoid liquid spillage
When performing sample manipulation, make sure that the sample does not spill onto the water quality analyzer. If possible, use a protective shield or other protective measures.
6. Keep the operating room clean
If the instrument is placed in a laboratory or operator room, ensure that the overall cleanliness of the operator compartment reduces the likelihood of dust and particulate matter entering the instrument.
7. Use a special sample container:
Use clean, dedicated sample containers and avoid containers that may have dirt or chemical residues. Avoid using container materials that may corrode or contaminate the water quality analyzer.
8. Clean up the leakage in time
If a leak occurs during sample handling or instrument operation, clean it up promptly and ensure that the leak does not enter the instrument. Use appropriate absorbents and cleaning methods.
9. Regular maintenance:
Perform regular instrument maintenance, including cleaning, calibration, and replacement of aging parts. Follow the manufacturer's maintenance guidelines to ensure the instrument is kept in good working order.
When dealing with external contamination of water quality analyzers, special care should be taken to use appropriate cleaning agents to avoid damage to the instrument. At the same time, regular training of instrument operators to improve the awareness of instrument maintenance and protection will help reduce the impact of external contamination on the instrument.
