aeoneal writes "According to Science Daily, mass spectrometry is no longer limited to what can be taken to the lab. Purdue researchers have created a device they liken to a tricorder, a handy 20-lb. device that combines mass spectrometry with DESI (desorption electrospray ionization), allowing chemical composition to be determined outside of a vacuum chamber. Purdue suggests this could be useful for everything from detecting explosive substances or cancer to predicting disease. Researcher R. Graham Cooks says, 'We like to compare it to the tricorder because it is truly a hand-held instrument that yields information about the precise chemical composition of samples in a matter of minutes without harming the samples.'"

smells like ... the future (Score:5, Funny)
In 1992 Harry Harrison (of SF fame) and Marvin Minsky (of AI fame) collaborated on The turing option [amazon.com], trying to merge Minsky's ideas about how an artificial mind could work with a SF story. Wasn't exactly a masterpiece, but there was an astonishing twist: In the book a brilliant scientist creates the first true AI and embeds it into a sort of fractal robot, whose arms are split into more arms like branches on a tree, ending with thousands of autonomous arms with their own vision each. And the first place this system is used (after being stolen): in agriculture, picking up bugs.
So I will predict the first mass use of Purdue's Tricorder: Japanese toilets!!! [wikipedia.org]. It can already recognize "biomarkers" in urine, so someone will build a cheap version of it into a toilet and every time you take a dump it will tell you what you should not have been eating, how sick you will be tomorrow and that if you continue that way your insurance won't cover your therapy. It will save the health systems billions.
.Oh, and I'm serious about the toilet part.

The first use will be counterterrorism/counterinsurgency, the second law enforcement. In the law enforcement context they will analyze the air around you when they stop you to chat, pull you over, etc. The molecules leaving your body/clothing/car will enter the public domain atmosphere and be fair game for analysis. It think there is precedent from having dogs sniff the exterior of a car at a border crossing, the pot smell entered the public domain, the trained dog signaled, instant probably cause for a search. Similar justifications will be safety related. "I need to interview you, but first for your safety and mine, I need to scan you."

A related note, a lot of money on the also has measurable levels of meth.
I don't think the point to this how much money is involved in drug trade, but rather how inter-connected out money is, and how good our analytical chemistry techniques are.
Although... a terrorist would probably be using money that hasn't been in wide circulation - perhaps we could spot them by seeing if too much money any individual is carrying is devoid of drugs.

What a great logical conclusion. I can just see a politician/cop/prosecutor thinking this. Clean money = terrorist. Dirty money = drug user. Lockem up!

Must be the ST:TOS version. At 20 lb, I would imagine that a shoulder strap is mandatory wear. Thanks, but I'll wait until the ST:TNG version hits.

Sergeant: Sir, according to this device, the cartoon character is made of plastic. If I remember my extensive training at community college correctly, bombs can be made of plastic explosives. I recommend we shut down the city and destroy all the cartoon characters at great expense to the taxpayers.
Mayor: Sergeant, why waste all the taxpayer's time and money on a few lamps?

but is there a real need for mass-produced mass spectrometers?
Never get ripped off buying blow again! Yeah!
Also, the next cop who busts me might find it useful for testing my 'stash' without destroying it. Farmers could do soil tests out in the field. Ambulance crews could use it for quick diagnosis. A school could have one to transfer between the science classes. And of course Homeland security will buy these by the dozen (* as long as there is a couple good Republican donors on the company's board)
Re: (Score:3, Insightful)
Police, airport security, and military applications spring to mind easily. The article did point out that they could detect cocaine residues. Other drugs, and explosives are just as easy I'm sure. I wonder what the range is?
