I am testing Acid number in Avalure AC 315, using Phenolphthalein as an indicator and 0.10N NaOH as titrant..it is giving me the results out of spec, towards lower end. i talked to the vendor and they used auto titrator with electrode without any indicator. My question is can i use pH electrode to get the end point?, rather than Phenolphthalein. Only problem is I dissolved the Avalure polymer in 49:1 (acetone:H2O), so any recommendation for organic solvent electrode
which would be appropriate for the organic solvent matrix. please let me know. Thanks
