the Man -Post 345:
You quote advice from Duke University. I have checked with the makers of this instrument, and they see nothing wrong with using a 1200 grating instead of 2400, but the resolution will be halved. Someone ought to perform independent, and very careful, measurements: Mills would supply the hydrinos “in a bottle” on request. Actually bound to gallium oxide, released by heating above 900 °C. But this forum is not the best place to make such a suggestion: you are all having so much fun.
