    New test for caffeine

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    This will be a neat tool to have once its available:

    Jack Ladenson is one of thousands of Americans bothered by caffeine. The older he gets, he says, the more he switches to decaf coffee.

    The problem is he never trusts what hes getting in coffee bars or restaurants. So Ladenson, a chemist, is working on a dipstick that would measure levels of caffeine on the spot.

    It will be interesting to see how they market this. While it would be a very simple and easy test to conduct and interprert in a lab Im afraid most average joes would be at a loss as to how to interprert the test results.

    Tests of this type give you a concentration level of the chemical theyre looking at, in this case caffeine, usually given as ppm (parts per million). A meaningless number to the nonchemists out there.

    Because the stick does not know the volume of the drink it cant tell you directly how many mgs of caffenie there are in it.

    The data from the stick whether given as x number of bars or as a color or what-ever is going to have to either be run through a formula or more likely in the case of a test for the general public cross referenced with a chart to actually tell you how much caffeine is in the drink.

    Having observed the problems people have with a simple ph test strip it would be entertaining, not to mention painful, to watch them try and figure out how to use and then interprert the results of this test.

    Notwithstanding the requirement to be able to interpret the results correctly, it would be an interesting tool for those of us interested in caffeine levels and consumption. But ultimately it would also depend on the cost.

    And some guidelines on what is considered the medically accepted range would be interesting also....

    But then most of us seem to have some idea of what is a reasonable consumption for us as individuals, and the time of day, etc.

    Hmm, sounds like a bit of fun for a while.

    yum yum..

    who wants to dip a stick coated in llama or camel antibodies into their latté?

    can you just imagine waiting 2 minutes for the strip to register while your coffee goes cold and all those beautiful oils evaporate.. egads!

    give me my coffee quick and go heavy on the caffeine thanks!
