The operation process of a portable ammonia nitrogen analyzer mainly includes preparation work, sample collection, sample measurement, measurement process, result recording, cleaning and maintenance, shutdown and storage, etc. The specific operations are as follows:
1. Preparation work:
Ensure that the instrument is calibrated and the required battery is fully charged.
Prepare necessary sample containers, sample collectors, reagents, and standard solutions.
2. Sample collection:
Use appropriate methods to collect samples and ensure that they meet the required standards and sample preparation procedures.
Some samples may require filtration to remove particulate matter.
3. Sample measurement:
Turn on the instrument and wait for its initialization.
Use the menu on the operation panel or screen to select the ammonia nitrogen detection mode.
Add reagents to the sample and wait for reaction.
Place the sample after the reaction into the instrument for testing, or place the ammonia nitrogen electrode in the water sample to be tested.
4. Measurement process:
Wait for the instrument to measure the concentration of ammonia nitrogen in the sample, and the results will be displayed on the screen after the detection is completed.
5. Result recording:
Record or print measurement results, including measurement values, measurement date and time.
If necessary, store the results in the instrument memory or export them to a computer or data recording device.
6. Cleaning and maintenance:
After completing the measurement, carefully clean the electrodes or sample containers to ensure they are not contaminated.
7. Shutdown and storage:
Turn off the instrument to protect its battery life and storage status.
Store the instrument in a dry environment that avoids extreme temperature and humidity.
