Hi Lou,
Titration will usually give you more precise results.
There are several ways to do to use titration:
- Autotritration with pH/potentiometer is an excellent choice for a tight
control, but is rather expensive.
- Manual titration with a burette and colour indicator is usually more then
sufficient.
- Drop kit system might be appropriate if you need to verify a gross
approximation on the spot, this methods can be as the operator level
but is prone to error due to complexity in calibrating the size of
the
drops.
Just my 2 cents,

Subject: [TN] Saponifier concentration measurement
Technetters, how do you measure saponifier concentration in a board assembly
cleaning machine? We've been using a refractometer to measure degrees Brix,
but this is appears to be a "legacy" method. I've been hearing titration
would be the way to do it. Please comment. Lou Hart QA manager, Compunetix
