It would seem that Party #2 above would be an ideal candidate to forward his reactor to Deneum as they are unable to perform tests
I do not think Party #2 can do anything.
Deneum does not have a mass spectrometer. There is no point to trying to do this experiment without one. You are working blind with no idea whether sufficient purity has been achieved.
Let me restate this, as clearly as I can: People who are not skilled in the art cannot do cold fusion. People who do not have a complete set of instruments including a mass spectrometer, and who are not skilled in using these instruments, cannot do cold fusion. People who have to ask me or others how to set up the plumbing between the vacuum pump and the mass spectrometer, or what sort of plumbing to use, cannot do cold fusion. If you have to ask such things, you can't do it. That's what three top experts told me recently.
In my previous analogy I said this is like cooking an omelette compared to the 6-course meal that is the Fleischmann-Pons experiment. As you see, the latter takes months, or years, just to find a few good cathodes in a batch of 100:
(After a year you might find zero goods cathodes.)
Imagine you show up at an interview for a job cooking at a top restaurant. The head chef says, "okay, show me how you make an omelette." You say: "What temperature should I use? Should I use butter or oil? How many eggs?" You fail. You are not a cook.
