Paste solids measurement in real time |
摘要 |
A real-time method of determining paste solids includes: correlating the refractive index of a paste with solute concentration in a solvent using a plurality of paste solids concentrations, typically including at least two paste solids concentrations greater than about 5 percent; submersing a fiber optic refractometer sensor into a sample and allowing it to equilibrate for a period of from about 30 seconds to about 20 minutes prior to measuring refractive index of the sample; measuring the refractive index of the paste sample with the fiber optic refractometer sensor; and determining the concentration of solute in the sample using the correlation. |
