Coooool
A tip of the hat to Bones McCoy. :-D
The "tricorder" meme has seriously damaged the chemical analysis instrument business. The only things the funding agencies offer grants for these days are "handheld diagnostics", which are simply not possible with any technology available today. And perhaps not ever. See "lab on a chip"......which has NOT materialized in any useful form.
Note that the system in this article ONLY does physical measurements or signals that are directly electrical/magnetic.
It "is" possible today to have a system that is about the size of a shoebox, but nobody is interested in that approach, simply due to the fictional "tricorder" meme.
