The co-surfactant bridges the oil and water interface and further reduces the surface tension of the system to zero. Figure 1 provides a schematic of the emulsion droplet showing the short chain alcohol, SDS, the octane droplet and the sodium ions surrounding the droplet. This flow is relatively rapid and is towards the cathode situated near the detector. The surfactant-coated oil droplets are negatively charged and therefore attempt to migrate towards the anode when the voltage is applied. However, the EOF is sufficiently strong to eventually sweep the oil droplets through the detector to the cathode.
P are determined to generate calibration graph or migration index.
Figure 3b shows the migration time data for these solutes plotted against their log P values. Proteins are generally too large to partition into a micelle but can partition into the microemulsion droplet which has a larger volume. Acids Hop bitter acids are present in the hops used to manufacture beer. The levels and composition of these acids affects the quality of the hop quality and is therefore tested before the hops are used in beer manufacture. Resolution of the 6 major hop acids was achieved within 10 minutes with separation efficiencies in the order of 280-480,000 theoretical plates.
