ADMIN NOTE: Hi All, a new topic for the discussion of the science from the SAM and Chemin instruments.
There has been a very important amendment to Rule 1.3 which is explained here. Please remember Rule 1.3 at all times when discussing matters in this section. |

The SAM results from EGU show significant differences to the previous ones. There are now 2 oxygen peaks rather than 1, and suggestions of a second oxidant, possibly hydrogen peroxide. The temperature of the CO2 release seems to have dropped, and it coincides with a dip in the O2. The team speculated that some carbon containing substance is being combusted by the O2 to produce CO2. There are also other possibilities.
The new results are from the same sample as the first ones were, so I don't know why the results are different. Maybe the heating was done differently. If combustion is the source of the CO2, then there is a lot of organic present, maybe 1% abundance. |
