Application of ionic liquids and various carbon materials in reference electrodes with carbon paste-based transducers

In this article it is proved that carbon pastes with ionic liquids (ILs) are a promising material for transducers of reference electrodes, which favors their miniaturization. Two ILs were used: 1-(2-hydroxyethyl)-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (IL1) and 1-(2-methoxyethyl)-3-me...
