Purdue Unveils a Tricorder 177

Posted by kdawson from the beam-me-up dept.
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.'"

    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.

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.

        I had a colleague who was testing out a new mass-spec machine (probably similar to the one in TFA) to verify cleanliness between campains at a plant site. The machine had been developed for use in airports, and the software already contained the profiles for a number of drugs and explosives. Apparently, as the sibling points out, coke is on a lot of our money. Most of the time it is in the ppb level, which could be transfer from money that was with money that was with money that was with coke. Occasionally however a bill would show 100 - 1000x the typical amount, we concluded that those were bills that made it into peoples noses.

One of these would allow for rapid trace chemical analysis in the field instead of collecting samples and taking them back to the lab (or to what before counted as "portable," an MS that could fit in a van).
