Claims (2)

Claims (all) which will not appear on the classifieds page:------10/09/2020------(OCR) 1.Electrochemical device for histamine detection. Mean using a graphene electrode consisting of a transparent sheet (1) as the base of the device to support screen printing of the electrode is characterized by an active electrode (2) with a graphene composition. It is screen printed on transparencies (1) which are the oxidized electrodes of estamine. The active electrodes monitor the changing electric current within the system which varies with the estamine concentration. The reference electrode (3) with silver/silver chloride (Ag/AgCl) composition is screen printed on the transparencies (1), acting as a comparative electrode which allows the determination of the sensitivity. The electrode potential difference (4) graphene-containing auxiliary electrodes are screen printed on transparencies (1) to help complete the electrical system. 2. Method for detecting estamine by electrochemical method using electrochemical device according to claim 1 with the following steps: Step 1 cut off the electrochemical device for Eestamine measurement. Tamine using graphene electrodes to size and connected to a portable potentiostat with clip-on wires Step 2 Prepare the estamine standard solution. In a 0.2 molar sodium hydroxide solution, acting as a step 3 electrolyte solution, 100 µL of estamine standard solution was applied to the electrode face. Covering all 3 poles as shown in Fig. 3, step 4. The amount of estamine was measured by electrochemical method by measuring the current using square-wavevoltammetry, SWV scans for potentials from 0.0 to +0.8 V using an amplitude of 0.075 V, a steppotential of 0.020 V and a frequency of 0.075 V. ) equal to 25 hertz. Step 5 for the quantification of estamine was done by constructing a standard graph using the measured current in microamperes (uA) as the y-axis and the amount of istamine concentration in ppm unit In the x-axis, it was found that the standard graph for the determination of estamine was in the concentration range of 5 to 100ppm--------------Page 1 of Page 1 Claims. 1.Electrochemical device for the determination of histamine using screen-printed graphene electrodes on a transparencies base comprising 1.1)transparent plates for device base (1)1.2)active electrodes with Graphene composition (2) 1.3) Silver/silver chloride-containing reference electrode (Ag/AgCI)(3)1.4) Graphene-containing auxiliary electrode (4) 2.
