What are the similarities between capillary electrophoresis and high-performance liquid chromatography (HPLC)?

Both CE and HPLC offer high separation efficiency, allowing for the complex mixtures to become individual components. Both techniques are also highly sensitive and capable of detecting and quantifying molecules at low concentrations. Another similarity is that they both require minimal sample preparation, which simplifies the process for analysis. Additionally, CE and HPLC are widely used in various fields, including pharmaceuticals and clinical diagnostics.
