So Deionized water has high ion concentrations, never knew that.

We have inherited the need to monitor saponifier concentration and would like to avoid the need to perform titration testing and would obviously like to introduce continuous monitoring if possible. Is refraction commonly used as a measurement method

How do yall monitor the concentration of yer saponifier? [NOTE: This is a BIG chance for NC flux-types to make smart remarks in retribution for remarks made about removing solder balls in an aqueous cleaner.]

Another measurement tool is a refractometer to measure light refraction. The saponifier will have a specific refraction property is measure agianst an index.

I concur with Pete. We use a refractometer to measure soponifier concentration.It is simple fast and straight forward. Cal

Dunno, but if I had to guess, your DI is corroding the stainless. But then again, some saponifier concentrations can be overly caustic

I like the idea of a bulbous sucking device - can I get one with large cups instead of small?

Yes, it is quite common. Does it [refraction] provide adequate resolution? => Depends on: * What you mean by �adequate�. * When during the process [cleaning solution life] you make the measurement. Is the [refraction] measurement affected signifi

Saponifier effect on Al pad

Electronics Forum | Fri Jan 07 10:27:07 EST 2011 | patrickbruneel

Hi, Detergent/saponifiers have indeed the potential to tarnish aluminum. This is due to the high alkalinity of the chemistry (pH 10-12). Things you can do to minimize the effect is: A) Limit the exposure time of the Al with the chemistry. B) Reduc

We use a Hach digital titrator. You can buy a digital titrator kit, hydrochloric acid, phenolphthalein indicator powder pillows, turkey baseter (or some bulbus sucking device) and a couple small measuring cups. We do tests twice per shift (more is
