Capel®-205 is a new generation capillary electrophoresis system with advanced options and design. Its main features are:     
     

Extended autosampler capacity up to 59 positions, allowing to provide overnight analyses     

Standard centrifuge-type vials of 1.5mL volume (Eppendorf-type) closed with their original caps are used for all solutions     

Specially designed unit automatically opens vials just prior to their use, thus preventing evaporation and any kinds of cross-contamination     

New HV block provides voltage up to +/- 30 kV thus improving separation efficiency and decreasing analysis time     

Optionally – integrated unit to control the state of the inner capillary surface provides significantly improved migration time reproducibility especially when analyzing samples with complex matrices     
     
Thus Capel®-205 can be the very best choice not only for R&D and low-scale analyses but also for the customers dealing routinely with dozens of samples per day.     
     

PRINCIPLE OF OPERATION     
High performance capillary electrophoresis is based on the differential migration of components of aqueous samples within a narrow fused silica capillary driven by an electric field. Separated solutes are quantitatively detected at the capillary outlet by a high sensitive optical system based on direct or indirect UV absorbance.
