摘要: Abstract This work presents a flow analysis method for direct quantitation of calcium carbonate in cement without pretreatment the sample. The is based on online vaporization CO 2 gas following acidification sample inside small chamber that has acceptor solution passing around it. Solubilization into stream changes conductivity causing an increase signal at capacitively coupled contactless detection (C 4 D) placed outlet chamber. adaption from previous reported ‘membraneless vaporization’ (MBL-VP). can be used quality control production mixed cement. These materials usually have contents high concentration range (e.g., 33–99% (w/w) CaCO 3 ). Analysis samples by this and convenient as it requires no pretreatment. low-cost with satisfactory accuracy acceptable precision.
