How is the AdBlue sample taken correctly?

General guidelines for AdBlue sampling

1. Be sure that the sampling point is clean. In case it’s not clean then rinse it with demin water.
2. Samples must be taken and kept in clean odorless containers made of HDPE or suitable materials such as HDPP. Metal jars may not be used for AdBlue due to the risk of contamination from metal. Samples must be protected from contamination prior to analysis. Devices used for sampling must be clean and suitable.
3. All samples must be representative of the entire batch and labeled in the following manner:
   • Product name
   • Customer name
   • Batch number of IBC / cannister
   • Date & time of sampling             
   • Address of the sampling location
   • Name of the person who took the sample
4. Take a clean plastic bottle of size 1 litre (preferred) or minimum 0,5 litre.
5. Place this plastic bottle under the sampling point and open the “valve” slowly. Fill the bottle half way and close the valve.
6. Close the bottle and shake the bottle carefully.
7. Open the bottle and pour out all of the AdBlue (in a waste bottle).
8. Repeat step 4 but now just fill the plastic bottle upto 90-95% max. Make sure no insoluble/dirt particles enter the bottle from the sampling point or valve.
9. Close the valve and be sure that the plastic bottle is closed tightly.
10. Put the bottle in a plastic bag and close it carefully to prevent any possible contamination. Label the sample bottle as well the plastic bag according to step 3.
11. Prior to the analysis, these samples must be stored according to the right conditions (temperature < 25°C and not under direct sunlight).
