First, check the USB-C type cable to ensure it is properly connected. Then, go to the PC settings and open the Control Panel. Navigate to "Ports (COM & LPT)" and check if the USB drive is recognized. If it is not showing up or is listed under "Other Devices" as FT232R USB UART, try to install the appropriate driver provided in the Pen drive along with the instrument.

The dummy test cell provided with MedPstat is primarily used for calibrating instruments and checking the current ranges. So, we provide a 1K resistor, which allows for easy testing of the instruments. If you encounter any issues or have doubts about the readings, simply connect the instrument to the dummy cell and run one Linear Sweep Voltammetry (LSV) from -1 to 1 V. In the result plot window, observe that the current range is displayed from -1 mA to 1 mA.

The choice between SPEs and three-electrode systems depends on experiment or application. Both offer benefits. The "better" system will vary depending on the experiment's design and requirements. SPEs over conventional 3-electrode system: Convenient and user-friendly. Cost-effective because all the 3 electrodes are integrated on a single substrate. As a result, no requirement for individual counter, working, or reference electrodes. Cleaning is not mandatory in between experimental trials they are disposable and hence time-saving. Minimal area for the experimental setup. Better sensitivity and ease of modification. Point of care and on-site analysis.

Applications of SPE based electrochemical sensors: Electrochemical sensors based on SPEs are more efficient and convenient in performing point of care analysis using electrochemical techniques compared to traditional benchtop experiments. Food industries – To examine the ageing, sulphites level, and allergenic protein in wine samples. Environmental monitoring - Organic, inorganic, and biological pollutants can occur in soil and water. SPE based sensors are employed in the detection of pesticide and herbicide contamination in soil as well as the monitoring of heavy metals such as Hg2+, Pb2+, Cu2+, and Cd2+ in water. Forensic Electrochemistry – SPE based sensors are used to...

The most often and convenient method to clean SPE is using an H2O2 solution and performing multiple Cyclic Voltammetry cycles at a low sweep speed. Carbon-based SPE electrodes are washed with ethanol followed by soaking it in 0.01 M hydrochloric acid solution. For cleaning Gold and platinum-based SPE electrodes, the negative sweeping method is preferred as it increases the roughness of the electrode surface. [Reference: 10.3390/pr10040723]

Different techniques are used to clean SPE, depending on SPE surface type and level of contamination. The cleaning may be further divided into three types: Chemical cleaning methods (using solvents). Piranha solution (owing to strong aggression, not preferred). Aqua regia Thermal cleaning method: UV ozone cleaning Electrochemical cleaning methods (using cyclic voltammetry (CV) and Electrochemical Impedance Spectroscopy (EIS) technique) KOH sweep method. Potential cycling using H2SO4 or HCl. CV sweeping using potassium ferricyanide. Taking negative sweeping potential (using CV technique). [Reference: 10.3390/pr10040723]

The Counter Electrode (CE) in SPE is made up of carbon ink because of the low cost and inertness. The main purpose of the CE is to maintain electrical neutrality and it helps to complete the circuit. The Working Electrode (WE) is usually made up of silver, gold, or other metals inks based on the application or target analyte as it must be sensitive to analyte concentration. Silver and silver chloride mixture ink is commonly used to print Reference Electrodes (RE) because of their low cost and easy availability. These silver/silver chloride inks are good conductors and it is very...

Screen Printed Carbon Electrodes are used only in aqueous regions and their thermal stability ranges from 10°C to 80°C depending upon the substrates used such as plastics since they are of low cost. Whereas, Gold and platinum screen-printed electrodes are used in both aqueous and non-aqueous regions and their thermal stability ranges from 10°C to 200°C since they are fabricated on ceramics.

Screen Printed Electrodes (SPE) are fabricated by printing on non-conductive materials like alumina, ceramic, and plastic which serves as the electrode's support. It consists of three electrodes namely, the working electrode (WE), Counter electrode (CE), and Reference electrode (RE), and these electrode surfaces are coated with various conductive inks like, WE (carbon, platinum, or gold inks) CE (Carbon ink) RE (silver/silver chloride ink) The electrochemical performance, selectivity, and sensitivity of the SPE based sensors are determined by different conductive inks like Platinum, Gold, Silver, and Carbon.

In general, inert nature of the platinum does not result in contamination, and washing with distilled water post-experimentation is sufficient. However, contamination can occur over time in the presence of strong acidic or alkaline solutions. In such cases, Piranha solution can be used to clean the contaminated platinum electrode. It is a mixture of sulfuric acid and hydrogen peroxide (1:3). Another method used to clean the counter electrode is to immerse the electrode in 10% nitric acid solution.

Platinum or Carbon as counter electrode material is preferred because both require low maintenance and don't easily get oxidized or reduced. Platinum: Platinum, due to its inertness and electrical conductivity, is found to be one of the best counter-electrode materials. Platinum electrodes are available in different forms such as - mesh, foil, wire, and tip. Based on experimental requirements, different forms of platinum electrodes are employed and a mesh kind of platinum electrode is widely used due to its high surface area and porous nature. Limitations: Cost-effective Carbon (graphite rods): Graphite rods are more affordable than platinum, have higher corrosion...

The counter electrode must be made up of inert metals like gold, platinum, or carbon species. It should have a large surface area, to enable a high current flow even with low potentials. Also, in general, counter electrode size is maintained slightly larger than the working electrode as it enhances measurement accuracy, minimizing the energy losses and the influence of electrolyte resistance.

The Counter Electrode serves two crucial roles, it completes the circuit and maintains electrical neutrality and it protects the reference electrode from any other potential changes. The main function of CE is to promote electron flow while minimizing any undesirable polarisation effects.
