文档介绍：SMDE Stable surface Needle Capillary Tapper Hg drop DME Droplife New Drop Electrode types in Voltammetric Analysis Differential pulse voltammetry Signal E I Resulting i-E curve t E W1/2 E0 Differential pulse voltammetry Differential pulse voltammetry Currents will only be measured close to E0 W½ = mV if the pulse height is small Advantages over Normal Pulse Voltammetry Cancellation of (capacitive) background currents Ability to distinguish close/overlapping peaks Higher currents and higher selectivity
