warren "Sorry, I've been coding. Some more thoughts: In the graph I posted of the basic, upgraded, and hi-res spectra, I realize it's hard to say what's m..." | Read more » over 9 years ago

warren "I love this test - the possibility of distinguishing mixed oils, even in a basic sense, is amazing. Have you done a 1:2 mix test for comparison? " | Read more » over 9 years ago
warren "For #4-6, I'm not sure I agree. The rigidity of the attachment of the Oil Testing Kit to the spectrometer itself only has an effect on amplitude, a..." | Read more » over 9 years ago
warren "Hi, Dave - thanks for the input, as always. As to #1, absolutely, as even a small movement can change the position of a spectrum. Do you feel that..." | Read more » over 9 years ago
warren ":-/ whoa! you have extras, right? And if not, they are sold in the PL store. Be careful! I don't know that type of laser -- how much does it cost? " | Read more » over 9 years ago

warren "Great, thanks. I think we could relatively easily find a heavier material to make this work. Would you be able to post the picture of your sleeve p..." | Read more » over 9 years ago
