Here's how these new reference standards were characterized.

The Canadian National Research Council?s Institute for Marine Biosciences (NRC-IMB) has signed an agreement with AB SCIEX that will enable researchers worldwide to benefit from the insitute?s experience in the detection and identification of marine and freshwater biotoxins and the creation of certified reference materials.

In 1958 the University of Chicago zapped a simulated primordial earth atmosphere with a series of electrical discharges to demonstrate the way in which organic compounds may have been originally synthesized on Earth. Archived and unreported samples have recently been uncovered and submitted to modern analytical techniques, which have revealed even more abundant amino acid and amine yields than previous experiments.
