No, in every case I know of, enrichment was done by the mass spectroscopy experts themselves, with in house equipment. There are no self-made gadgets involved. Miles did nothing to the gas samples. He sent them out as collected. > Rothwell talks about 16 others besides Miles… > I did not mention the other studies. Storms lists them. You can read the papers describing many of them at LENR-CANR.org. Here is the mass spectrometer at the ENEA: http://lenr-canr.org/wordpress/?page_id=187#PhotosENEAFrascati It does not look cobbled together or self-made to me. > so which of them also has access to a putative ppb MS, and which has not > relied on enrichment? > Most of them do not need ppb level instruments. Most collect the gas for a longer duration than Miles, with a closed cell. That concentrates the helium more. I would not call that "enrichment" because it implies they took something away leaving helium. Miles had an open cell that can only collect a fixed amount of effluent gas, over a fixed time period. (1 hour 15 minutes). > Why does Rothwell not identify the manufacture of this magical MS device, > so we can cross-check with the published specs from the manufacturer ? > The literature published by Miles and by the labs describes all this in detail. Let me repeat this quote: "We completed 18 measurements of excess helium for experiments producing excess heat. These helium measurements were performed at three different laboratories: the University of Texas (References 14 and 15), Rockwell International (Reference 22), and the U.S. Bureau of Mines (References 24, 25, and 31)." http://lenr-canr.org/acrobat/MilesManomalousea.pdf See that document for refs. 14, 15, 22, 24, 25 and 31, which will lead you to still other references documenting the claims. See also the Hoffman book describing Rockwell's mass spectrometer. > Probably because he knows the published specs do not support ppb. > Beene has not read anything about the instruments at U. Texas, Rockwell, or the Bur. of Mines. If he had read something, he would not be asking me for information. Since he has read nothing, he knows nothing, and he has no basis for making these assertions. > We should ask – why not – or why did Roulette/Pons – who had access to MS > not test at all? > How do you know they did not test? I have no idea whether they did or not. In any case, their cells produced about a thousand times more power than Miles, and the cells were closed for 3 months, whereas Miles' was open and could only collect for an hour and 15 minutes. So if they collected and analyzed helium they would have found far more. They would not need parts per billion levels of precision. - Jed
