Sampled DC polarography

  "id": "MLC-T-CHM-010501",
  "term": "Sampled DC polarography",
  "field": "Chemistry",
  "definition": "A variant of direct current (DC) polarography where the current is measured only for a brief period at the end of the drop life of a dropping mercury electrode. This technique minimizes the contribution of capacitive current, which can obscure the faradaic current. It offers improved sensitivity and detection limits compared to conventional DC polarography.",
