Consistent calcimetry methods and systems utilizing combinations of calcimeters and laboratory shakers

A method of determining carbonate content in rock samples, comprising:

• connecting a calcimeter to an acquisition system or an integrated central processing unit system configured for recording and/or receiving measured pressure values, wherein the calcimeter comprises a reaction chamber and at least one pressure sensor;
• placing a rock sample and HCl into an acid cup;
• placing the acid cup in the reaction chamber of the calcimeter;
• externally shaking the calcimeter with the acid cup or performing a shaking process in an integrated part of the calcimeter;
• recording, with the at least one pressure sensor, a first pressure value at or after a first time duration of shaking, wherein the first pressure value is indicative of first gas pressure within the reaction chamber at or after the first time duration of shaking;
• and
• recording, with the at least one pressure sensor, a second pressure value at or after a second time duration of shaking, wherein the second pressure value is indicative of second gas pressure within the reaction chamber at or after the second duration of shaking.
