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 the mixing fluid in a tank;
executing the cementing operation by mixing the mixing fluid 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 in the tank, wherein the tank is fluidly connected to the liquid additive mixing apparatus and the cement mixing unit, and wherein the CE instrument is disposed in the tank;
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.
