Hi there,

We were looking into KF titrators in order to monitor the dryness of the solvents that comes off our solvent system.  We were shocked at their price.

Is there no simpler/cheaper way to determine the dryness of your solvents...?

If not, recommend any specific type of KF titrator?


Thanks!

K-F is really the best.  If you're feeling up to it, you could try titrating the solvents manually, but that really sucks.  Sometimes you can send a sample of your solvent off to someone who already has a K-F titrator and they will run it for you.

Hi!
there are a lot of methods for drying solvent.
1. you can you CaH2 in order replace KF
2. You can you Dean-stark trap, it is very good and safe, i was successsful with my experiment.
3. you can dowloat furification solvent book for answering your question.
good luck!!!

In most of the cases (hexane, toluene, ...; of course there are some exceptions) the best system, for drying solvents, is Ph2CO + Na (or even alloy NaK), and than reflux it at least one or a few days. Of it has to be done in inert atmosphere (I suggest using of N2, the cheapest one, but not in all cases the best).

Mettler Toledo titrators are usually cheaper. Or you might buy a used one.
