1. A method for performing a cementing operation at a well site, comprising:
providing a liquid additive mixing apparatus that comprises a plurality of chambers containing additives, and further comprises a system for mixing the additives;
using the system for mixing the additives, mixing at least one additive with water to form a mixing fluid;
placing a first quantity of the mixing fluid in a first tank;
placing a second quantity of the mixing fluid in a second tank;
executing the cementing operation by mixing the mixing fluid supplied from the first tank or the second tank with a cement to form a slurry using a cement mixing unit;
using a capillary electrophoresis (CE) instrument to monitor at least one additive parameter of the mixing fluid in the first tank or the second tank, while the first tank or the second tank is fluidly connected to the liquid additive mixing apparatus, the cement mixing unit, and the CE instrument;
detecting at least one deviation from a predetermined tolerance for the at least one additive parameter using the CE instrument; and
taking corrective action to return the at least one additive parameter to the predetermined tolerance, wherein the corrective action comprises changing between the first tank and the second tank for supply of the mixing fluid to the cement mixing unit.
