G-IDE222

Interdigitated Gold electrode (Aux.:Au; Ref.:Au) / 10 microns lines and gaps/ Glass substrate

PL1

These practical kits allow students with or without electrochemical experience to complement their academicprograms by an inquiry-based learning on research experiences. They are also useful for those researchers that are starting in the biosensing field.Most of the methods described for ascorbic acid determination are based on the ascorbic acid oxidation, therefore Cyclic Voltammetry (CV) is used to identify the oxidation process over screen-printed electrodes. CV is a powerful technique also to determine if the process is controlled by adsorption or diffusion and study the effect of pH variation on the ascorbic acid electrochemical behaviour. On a second step, Differential Pulse Voltammetry (DPV) is used for developing an electrochemical method for ascorbic acid detection. Its analytical characteristics are determined and measurement of the analyte in a real sample is carried out in batch and in flow-injection analysis.The kit contains:• The professor outline• The student outline• A box of suitable screen-printed electrodes (50 units)• The needed analyte

They are also useful for those researchers that are starting in the biosensing field.Characterization of uric acid oxidation process is done by Cyclic Voltammetry, including if the process is adsorption or diffusion controlled and if the accumulation time could affect the electrochemical signal. Once a calibration curve is defined, the quantification of uric acid in urine can be easily done by direct quantification or bystandard additions methods. Real samples can be analyzed in a simple and easy way.The kit contains:• The professor outline• The student outline• A box of suitable screen-printed electrodes (50 units)• The needed analyte

G-IDEAU10

Interdigitated Gold Electrode / 10 microns lines and gaps / Glass Substrate

PL3

These practical kits allow students with or without electrochemical experience to complement their academicprograms by an inquiry-based learning on research experiences. They are also useful for those researchers that are starting in the biosensing field.The determination method is based in the electrochemical oxidation of acetaminophen to N-acetyl-p-benzoquinone imine. The identification of the reduction-oxidation process is done by CV that also allows to define if the process is controlled by adsorption or by diffusion. After process characterization, Cyclic Voltammetry and Square Wave Voltammetry parameters and analytical characteristics of both methods are studied and defined. Comparison of the results obtained with both electrochemical methods can be done by determination of paracetamol in pharmaceutical preparations by direct quantification or standard aditions. Also, Amperometric Detection (AD) is optimized in a flow-injection analysis system, defining the hydrodynamic curve and allowing the measurement of different samples under flow conditions.The kit contains:• The professor outline• The student outline• A box of suitable screen-printed electrodes (50 units)• The needed analyte

G-IDEAU5

Interdigitated Gold Electrode / 5 microns lines and gaps / Glass Substrate

PL4

These practical kits allow students with or without electrochemical experience to complement their academicprograms by an inquiry-based learning on research experiences. They are also useful for those researchers that are starting in the biosensing field. Stripping analysis is widely used in metal analysis. This technique incorporates an electrolytic pre-concentration step before stripping performed by a voltammetry technique. Cyclic Voltammetry allows to characterize and define the oxidation and reducction processes on screen-printed electrodes, as well as the possibility of applying this electrolytic pre-concentration step. Square Wave Voltammetry is used for an enhancement of the electrochemical signal once frequency, amplitude, potential and time of deposition are optimized. Analytical characteristics are determined and measurement of copper in tap water can be easily carried out.The kit contains:• The professor outline• The student outline• A box of suitable screen-printed electrodes (50 units)• The needed analyte
