Use of germanate as a background electrolyte for capillary zone electrophoresis.
The possibilities of using germanate as a background electrolyte (BGE) in capillary zone electrophoresis (CZE) were investigated. Germanate can be obtained with spectral purity and, due to its two pKa values, possesses higher buffer capacity and can be used in a wider pH range than borate. The advantages and disadvantages of germanate among other polyanions for use as a background electrolyte for CE analysis are discussed.
