Question on DSC

  1. Dec 14, 2009 #1
    My baseline for the DSC goes past zero (below 0 W/g) why would the instrument be doing this?

    This may be obvious, but: Bad calibration?

    it goes relative to the initial value you put in. the absolute number does not mean much.

    Perhaps you converted from one polymorph to another and a little energy was released? Have you run the same sample twice and noticed the negative value again?
