Mixing cell calorimetry

Mixing Cell Calorimetry (MCC) The MCC provides information regarding the instantaneous temperature rise resulting from the mixing of two compounds. Together, DSC and MCC provide a reliable overview of the thermal events that may occur in the process. 

Where the consequences of combining two or more materials under given conditions of temperature, confinement, etc., are unknown and cannot be predicted with certainty, testing may need to be performed to screen for potential incompatibilities. Two common test methods used for this purpose are differential scanning calorimetry and mixing cell calorimetry (described later in this section). 

Stripping is simple, rapid, and greatly expands MCA for these kinds of compounds. Microbial stripping of this kind likely would be helpful in analytical methods other than calorimetry but oddly this has not been developed. Table I summarizes the main points from numbers of plots similar to Figures 5a and 5b. The conditions were 5 x 1010 cells/ml, 6 to 8 x 10-3 mg compound to be stripped/ml, 30 second mixing. Glucose was stripped from 15 x 10-3 mg glucose/ml.
