having built the system and analysis method behind an absorption photospectroscopy (IR&#x2F;VIS&#x2F;UV) based device to measure a specific set of rigorously prepared and filtered bio-analytes, i would strongly advise against accepting this devices claims. Spectroscopy is a wonderful tool, but it&#x27;s not a new one, and far more sophisticated machines have tried and failed at this consumer level device&#x27;s claims. caveat emptor.
