pH measurement of dyes
Thread Content
Experts, does anyone know how to measure the pH of disperse dyes or solvent dyes? Are there any national or industry standards?
What is the medium you want to measure? Is it the aqueous phase or the organic phase that dominates? It is possible to choose pH probes with special applications. Could you please introduce the medium conditions and process parameters? It’s probably online measurement.
Our products are disperse dyes, all of which are insoluble in water. It’s not a test done online; rather, it’s to determine the pH value of the dye after it has been produced. I’m not sure if there are any standard guidelines for testing disperse dyes.
Just follow the procedures for testing; there are analysis procedures available for this
Do you have the analysis procedure for this? Can it be sent out?
I’m sorry, I don’t have it. However, it should be available in laboratories in the same industry. If you know the code for the analysis procedure, you can also get a copy from the local technical supervision bureau.
