YOUR SCANNING TECHNOLOGY IS RIGHT THERE IN THE MAIN BOOK ON PP. 254-255.
NO, IT'S NOT!
If you read the description on pg. 254 the chem sniffer tests the air for elements of the compounds in question. This works completely differently but often results in the same information.
It's like a different solution to the problem of "I want some of this guy's brains out of his head." You can walk up to him with a .44 magnum revolver and blow a hole into his head with a 240-gr boat-tail slug. You can also hook a hand valve up to a high-pressure vacuum system and spike a probe through their skull to suck some of it out. Same problem solved, just different methods.
A chem-sniffer takes an air sample and then runs the sample through a filter that is in turn tested for recognized compounds.
This machine uses a series of EM waves, not just millimeter-wave radar, to bounce energy from, not only an object, but also the
contents of an object to determine it's shape, composition, and density.
A chem sniffer can say, "This stuff is explosives"
only if residue, fumes, etc. of the explosives are getting into the surrounding air that the chem-sniffer is sampling. A cyber-scanner
only says, "Hey, that's not biological, is a weapon based on it's shape, or (if it's in the database) a cyberware implant based upon it's shape".
This new machine can scan a solid object that is
hermetically sealed and say, "There's explosives inside that" based upon it's combined EM return. It can also tell you what the casing around it is made of if you ask for this information and it's in the database. Cyberware? Sure, it can find it and it can also tell you what brand it is not only by shape but by the carbon content in the stainless steel or other materials based upon it's EM return, and shape, and configuration.
Yeah, this new-fangled do-dad does the same end result but it also does it better, more accurately, while providing a lot more information in more difficult circumstances, and for a whole hell of a lot more money.
