The Allende meteorite is the largest carbonaceous chondrite ever found on Earth. It fell on February 8, 1969, near the village of Pueblito de Allende in the state of Chihuahua Mexico. The original stone is believed to have been approximately the size of an automobile traveling towards the Earth at more than 10 miles per second. After breaking up in the atmosphere, it produced thousands of fusion crusted individuals and an extensive search for pieces was conducted which led into what is often described as "the best-studied meteorite in history". The Allende meteorite contains about 4% carbonaceous chondrites. The subject or organic compounds in meteorites was investigated by several authors [1-3] and for example the organic compounds of the Allende meteorite were analyzed by photoionization combined with TOF-MS and some PAHs compounds such as phenanthrene and pyrene were found [3].
Allende Meteorite sample was provided to Prof. Aviv Amirav by Prof. Richard Zare from Stanford University during the Isranalytica 2010 meeting in Tel Aviv in January 2010. The meteorite small stone was broken with a clean tweezers into small (about 1 mm diameter) stones and it was analyzed via the use of ChromatoProbe sample introduction device for intra injector thermal extraction followed by 5975-SMB GC-MS with Cold EI analysis.
