Hi experts of purified water,

Can anyone guide on using online TOC meters in purified water systems,
especially during installation. When offline systems were used from years,
definitely online systems are an advantage. Can it is installed in a system
just after UV system after generation in purified water, or it should be at
return loop.
What should be the PQ phenomenon and what should be the qualifications
criteria for and online system. Does it happen that A line meter shows high
conductivity and a low TOC. Both should be different meter at different
places or both should be measured by one unit. Can conductivity be
correlated with TOC.
