In this short 30 minute webinar we dive into understanding the common titration application known as TAN or "total acid number", also known as,  ASTM D664.  As part of our titration webinar series we have a fun and uncomplicated talk about this titration application known as "total acid number".  

In this short but informative webinar we explore:

- What is TAN, total acid number, ASTM D664?
- Why do we test for it?
- How do we test for it?
- How do you set up the titration application?
- What are common problems you need to avoid?
- Best practices you should know about and try to follow

It only takes a few seconds to register for this highly interactive webinar (recorded).  You will be able to watch, send us emails with questions, download various application resources including the application notes, electrode prep tips, and more.

This is a valuable tool for seasoned experts and first timers.
