5. Insert the acid dispensing probe when prompted.

6. When the titration is complete, a window appears to let you know that the analysis is complete. Click Ok.

   
   

   

7. A Gran-Method window appears with the results of the titration. Write the Alkalinity Cor value in the blue book. This is the result with the standard ratio applied to it. Click Ok/Save. This will upload the result to LIMS assuming the MUT uploader is active.
   
   

   When finished, clean vessel and the electrode.

   Click Ok/Save to save the results to the LIMS database. The value saved to LIMS and the value you need to note in the blue book is the “Alkalinity Cor” value. This is the value with the standard ratio applied to it.
