Acquisition and Manipulation Methods

Note much of this may be covered by just quoting the apparatus used. 

The results may be reported directly as mass of the sample varying with temperature or time, i.e. as m versus T. Thus a mass loss appears as a downwards curve. Instead of mass in mg, the scale may be converted into percent of the original mass. An alternative is to convert the results into a percentage mass loss. The scale is sometimes presented in molecular mass units, useful if the mechanism of decomposition is being studied. Particularly in the study of kinetics, another type of presentation is used the fraction reacted a. If the original mass is m, the final mass after the reaction has finished is and the mass at any time is m, then a fraction reacted may be defined as  

The fraction will be between 0 and 1. It should be noted that, if a
