Examples of use:

• Mercury drop electrode as working electrode for electrochemical investigations
  
  Advantage: constantly renewable metal surface both as static drop and continuously dripping
• Polarography for the trace detection of electroactive organic molecules and various metal ions, e.g. for quality control of an analyte
• Determination of redox potentials e.g. in the degradation of ascorbic acid

Device configuration:

• Investigations on a continuously renewable drop of mercury
• 3 modes available
  • CGME: Continuous growth of a mercury drop, computer controlled by a pulse sequence
  • DME: Constant drop growth/lifetime controlled by gravity
  • SMDE: Static mercury drop
• Integrated magnetic stirrer with speeds of 50–800 rpm
• Integrated gas purging with nitrogen
