Jphii, you will also need a small pump. As I was explaining Paul, resin tanks/cartridges need minimum flow/pressure throughputs in order to avoid channeling and optimize laminar flow down the bed. Channeling happens when there is not enough flow/pressure and the water flows down a narrow funnel path, using only a small portion of the resin and prematurely exhausting it, causing breakthrough. This is readily visible, as I had tanks channel on me when the customer gave me insufficient water flow/pressure.
The people at Aquatic Ecosystems are a competent staff and will be able to give you all the technical support you need. They flew me for an interview in Orlando back in May (but didn't hire me). Their technical manager, a civil engineer w/ a PhD, didn't know I was there and was forced to interview me on the spot. He started asking me questions about fluid mechanics, pumping systems design and stuff I have absolutely no knowledge of! Oh well, I didn't see me in call center 8 hours a day anyway...
The technical info I've given is not to brag, but necessary to understand and operate a little system like the one I recommend. Paul is right about gases--they will diffuse back into the water and make it "not ultrapure", especially CO2. The anion resin will be the first to exhaust, since CO2 hydrolyzes into carbonate, bicarbonate and carbonic acid (the water will tend to become acidic then). As the resin exhausts it will be unable to adsorb the heavier/more positively charged ions and will dump them, favoring the lighter/less charged ions.
This little system will be able to deliver water of a purity that's pretty close to that one used for nuclear reactors in submarines: they distill seawater and then run it through resins. Do not use any activated carbon, even if tempted. That will clean the water but load it with organic carbon compounds ( NO! ). When the system is started in needs to be flushed till water reaches proper conductivity/specs. At Beaver Balley nuke they use stationary & mobile equipment with the carbon/hydrazyne deoxygenating rig prior to the resin trailer and on a Monday it takes two-three hours of flushing to bring the organic carbon levels down to spec. In the mobile trailers I have used (fed with tap water) spec will usually be reached within 5 to 7 minutes. If using distilled water I'd give an educated guess of around 3 to 5 minutes. That means it's more practical to make smaller batches of demin water and fill them to the top, airtight. Using the system often and making small batches will prolong the service life of the resins.
Is it worth it? I think so. Doing a final rinse with ultrapure water will extract what's left on the record surface and the results will be more worthwhile than using this or that $700 power cord, for sure. I have talked about this with Jena Labs (Jennifer Crock) and she gets better results as the water gets purer and purer. On another note, once the record has gone through a two step cleansing an occasional cleansing with ultrapure water might be all that is needed if there's no fungal growth and/or fingerprints on the record surface.
Well Sean, that was a very short "self imposed vacation". Now you understand how I feel when you start getting technical and I state that I don't know how to read! I have no electrical/electronics knowledge but I *do* know my water. It takes all kinds...
