Temperature increase in capillary electrophoresis (CE) due to Joule heating is an inherent limitation of this powerful separation technique. Active cooling systems can decrease the temperature of a large part of the capillary but they leave "hot spot

We coin a term of milli-free flow electrophoresis (mFFE) to describe mid-scale FFE with flow rates intermediate to macro-FFE and micro-FFE (μFFE). Introduced decades ago, mFFE did not find practical applications. We revive mFFE, as we view it as a v

Electro-migration techniques, such as electrophoresis, are widely utilized in analytical sciences. If a single electrolyte is used, the field strength is typically assumed to be well-defined. Heat-associated field distortion (HAFD) has been suggested

Micro-free flow electrophoresis (microFFE) is a technique that facilitates continuous separation of molecules in a shallow channel with a hydrodynamic flow and an electric field at an angle to the flow. We recently developed a general theory of micro

A capillary or a narrow channel is an attractive medium for studying reactions. A capillary can serve as (i) a microreactor for carrying out a reaction in a nanoliter volume and (ii) a separation column to separate the reaction products prior to thei

Ionic electrophoretic mobilities determined by means of CE experiments are sometimes different when compared to generally accepted values based on limiting ionic conductance measurements. While the effect of ionic strength on electrophoretic mobility
