Figure 5From: The effects of instrument parameters and sample properties on thermal decomposition: interpreting thermal analysis data from Mars Onset temperature vs. flow rate for Iceland spar calcite (<53 μm particle size) with N 2 (black squares) and He (blue circles) carrier gases. Higher flow rates (shorter evolved gas residence time) leads to lower decomposition temperatures for a particular carrier gas because the decomposition reaction takes place at a faster rate.Back to article page
