There have been several technologies for non-invasive blood glucose monitoring, like light, raman spectroscopy and whatever but afaik none of them delivered reliable data. So I'm a bit sceptic if this emission spectroscopy could work.
Please, read some articles about accuracy of measurements based on emission spectroscopy. And youll find out that it is one of the best method, especially, when youre working with small concentrations of gases.
