A scanner that scans for colors can only read what it sees.
If the container is clear - it reads through the container into the sample. If the sample is clear - it reads through the sample into the background behind the sample.
Absolute black is the only surface that should not reflect back any light - however absolute black is not readily available although some paints and materials can get close to absolute black.
From my view of the product, the video and the promotion does not take into account for the container factor.
This is not a problem if you are scanning opaque solid or opaque liquids.
I see the scanner's usefulness within industry to compare material qualities that are controlled. It does not matter what the background is if you always use the same background. So I could compare powders, or liquids in a laboratory environment without any problems.
However, a universal ChromeID is more difficult when you suggest that the company will provide a reference sample comparative. The container of the reference sample and the container of the customer sample would have to match.
The ChromeID is also a problem in mixed solutions - such as oil and water or (salt and pepper mixtures). It can't separately identify the components out without separating them first. So while the company suggests that the scanner might be used for water quality, how are they going to identify the components in water? If they can separate oil and dirt particles from the water with a centrifuge, then you can identify the oil separately from the water. Again, this needs to be done in a lab.
Please do not make statements that do not make sense and add the disclaimer - 'just my understanding'.
