Hi Harold,

We have had two Shimadzu TOC's over the last 18 years. We ran the
the first one daily for about 14 years when it gave up the ghost and
we decided to purchase another. We do not run brine samples as you
do, but I imagine that would just mean you will have to do more
washing of the catalyst - I wouldn't think it would be a big issue.

Cheers,
Kerry
