2、 Test steps for wet laser particle size analyzer
Winner2009 wet laser particle size analyzer, as an intelligent fully automatic laser particle size analyzer, has relatively simple experimental steps, but it still needs to strictly follow the operating procedures to ensure the accuracy of measurement results. The following are the specific experimental steps:
1. Instrument preparation
Ensure stable working voltage and avoid voltage instability or pulse interference that may affect the instrument.
Check whether the instrument is placed steadily and firmly, avoiding vibration and knocking.
Connect the power supply of the instrument and preheat it to ensure that all measuring units of the instrument are in normal working condition and the laser power is stable.
Ensure that the laser particle size analyzer is properly connected to the computer and start the relevant analysis software.
2. Sample preparation
Select appropriate dispersants according to experimental requirements.
In a beaker containing a suspension, place an appropriate amount of the test sample and add a suitable dispersant.
Place the beaker into the ultrasonic cleaning machine to disperse the sample. Pay attention to the dispersion of the sample and adjust the liquid level appropriately to ensure uniform dispersion of the sample.
3. Parameter Settings
Open the software and set the parameters reasonably according to the requirements of the tested sample, including refractive index, analysis mode, sampling rate, testing times, etc.
Perform background measurements to ensure data accuracy.
4. Start measurement
Ensure that ultrasound, circulation, and stirring are all turned on.
After the data is basically stable, start recording the data. Generally, after recording more than ten pieces of data, take the average as the result.
Observe the laser opacity during the measurement process to ensure that it is within the set range.
5. data analysis
Record the stable measurement data and conduct further analysis.
To export and print data, relevant operations can be performed in the software.
6. Equipment cleaning
After the test is completed, rinse the sample tank with clean water or other liquid circulation to keep the equipment clean.
Turn off the instrument and computer in order, clean the cycle injector, and then turn off the injector power.
7. Instrument maintenance and upkeep
Regularly maintain and upkeep the instrument, including cleaning the optical path, checking the laser light source, updating software, etc.
Pay attention to environmental control and avoid environmental factors such as temperature and humidity from affecting the instrument.
Provide professional training to operators to ensure standardized operations.
