1. Cleaning and maintenance
External cleaning: After daily use, wipe the instrument casing and sample chamber with a soft dust-free cloth or a cloth dipped in a small amount of deionized water to prevent liquid from seeping into the interior.
Internal cleaning: Regularly inspect the lens of the sample compartment, gently wipe it with specialized lens paper or dust-free cotton swabs, and strictly prohibit the use of organic solvents or corrosive cleaning agents.
2. Laser management
Following the principle of "ready to use and on", turn off the laser when not measuring to extend its lifespan (such as the He Ne laser lifespan of about 10000 hours).
Avoid frequent power on and off to reduce the current impact on the laser.
3. Environmental control
Temperature and humidity: Maintain a stable laboratory temperature (20-25 ℃) and humidity of 45% -65% to prevent optical components from being affected by moisture or static interference.
Shock absorption and light avoidance: The instrument should be placed on a stable table, away from vibration sources and direct sunlight, to avoid light path deviation.
4. Operating standards
Before measurement, a benchmark check and optical path calibration are required to ensure data accuracy.
The sample should be fully dispersed to avoid large particles blocking the pipeline or bubbles interfering with the detection.
5. Component inspection and maintenance
Regularly inspect the waterway system, water pumps, and cable connections to ensure no water leakage or poor contact.
The injector and sample tank should be thoroughly cleaned after use to prevent residual contamination.
6. Other precautions
When it is not in use for a long time, it should be covered with dust-proof cloth and regularly powered on for maintenance.
If there are abnormal data (such as large particle peaks), repeated testing or electron microscopy verification is required.
