As shown by the equations below, the slope can be written as a “Cell
Factor” to multiply the pressure reading by to directly obtain percent-
ages of Calcium Carbonate and Dolomite.
As described above Slope = 20 PSI for a 1g sample therefore

% Dolomite =
or
% Dolomite = 4.6 × (Total Pressure - CaCO
