Purdue Unveils a Tricorder

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.'"

Take a good look..

Remember what calculators and computers looked like 20 years ago? In a couple of decades we'll be looking at these pictures and laughing ourselves silly at the description 'portable'.

First use will be military, second law enforcement

So I will predict the first mass use of Purdue's Tricorder: Japanese toilets!!!. 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.

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."
