    Ricin possibly found in letter to US Senator

    Who knows if related or not to Boston event:

    Washington (CNN) -- An envelope that tested positive for the deadly poison ricin was intercepted Tuesday afternoon at the U.S. Capitol's off-site mail facility in Washington, congressional and law enforcement sources tell CNN.
    After the envelope tested positive in a first routine test, it was retested two more times, each time coming up positive, the law enforcement source said. The package was then sent to a Maryland lab for further testing.
    The envelope was addressed to a U.S. senator, though the sources would not say which one.
    Ricin is a highly toxic substance derived from castor beans. As little as 500 micrograms -- an amount the size of the head of a pin -- can kill an adult. There is no specific test for exposure and no antidote once exposed.
    It can be produced easily and cheaply, and authorities in several countries have investigated links between suspect extremists and ricin. But experts say it is more effective on individuals than as a weapon of mass destruction.
    Ricin was used in the 1978 assassination of Bulgarian dissident Georgi Markov. The author, who had defected nine years earlier, was jabbed by the tip of an umbrella while waiting for a bus in London and died four days later.

    • You have to wonder how they are testing now. The company that provides all the anthrax testing systems and disposables is Cepheid. The atomic weight is 32,000 and if Implant was using its mini spectrometer it could only detect up to 500 according to ION Metric's website.

      I think it takes a larger more sophisticate mass spectrometer to ID complex proteins.

      However if particulate containing ricin or anything else were ionized, degradation byproducts might be ID'd as the first alarm. Then the much slower Cepheid style polymerase chain reaction voodoo kicks in. This might be what they do now with other companies spectrometers as the first detector.

      Sentiment: Strong Buy

    • can imsc's products detect trace amounts of ricin?
