though im not familiar with the technique mass/spec technique you describe. Frankly, when confronted with resolving microscale composition (quantitatively, not just analytically) on a "thick" surface you have to use some form of ion beam scanning/electron microprobe but, obviously, the sampling volume is way over the scale of even the largest QDs (about 100nm, and that is the scale of lateral resolution one needs, not sure if the ablation technique can achieve this resolution, the "best" laser spot size you can achieve optically is bout 2 um, also way too large by a factor of at least 20...).In this case the easiest way would be to make cryo-sections (audiophiles would like that very much :-) of the sample and use scanning TEM/EDX and diffraction for analysis....or dissolving the matrix phase (most polymers have a solvent) to extract the QDs, re-deposit, aggregate..etc., ect. Even though the weasels that manufacture the chip could simply sputter coat those at some limited cost/chip. I suspect they operate under the assumption that, we, audiophiles, are fools (good assumption???)
you know the most amazing thing is that The Chip has taken such a hold, on this forum..its like weed, it won't die...im amazed at the tolerance for non-sense some can display.
