Continuous deionization of latex suspensions

A new, fast, and reproducible method of preparing ordered colloidal suspensions at very low salt concentrations is reported. Preparation times are reduced by 2 orders of magnitude compared to those for the usual methods. Particle concentration and salt contents can be monitored and controlled by optical and conductivity measurements. Transient effects appearing during continuous deionization of the sample are reported, and qualitative explanations of these effects are suggested
