Yep, TEX, it can be done as described.
I had so posted previously. One needs a standard mixture that can be signatured.
What Valimed will not do is determine if the mixture is contaminated, unless the contamination is such to effect (change) the signature of the sample under test.
Quite simply, it can only compare the sample in question with a known and signatured sample.
It cannot identify an unknown and unsignatured, and report what it is.
If one gets a fail to pass read out, other methods have to be used to determine why it failed. But Valimed cannot tell them that.
This may be very important to the pharm lab.. they need to know what the heck happened.
