General information

Short Summary
A Spanish research group offers electrochemical sensor capable of performing in-situ sampling to determine simultaneous concentrations of sulphur compounds and 4-ethylphenol.

The research group is looking for commercial and/or research and development cooperation agreements.
Full Description
The Spanish research center has successfully developed various chemical devices. The main objective of this group is to design and construct cutting-edge tools that can contribute to advancements in the food industry.

This technology is based on an electrochemical sensor designed for the simultaneous detection of mercaptans and 4-ethylphenol in wines. The sensor utilizes dual-screen-printed carbon devices where the working electrodes are modified with cobalt phthalocyanine (CoPh) and fullerene (C60). The electrode modification enhances the conductivity, sensitivity, and selectivity of the sensor.

The detection method is conducted in the gas phase, avoiding direct contact of the sensor with the wine sample. This is crucial for maintaining product quality. The four electrodes (two working, the auxiliary, and the reference) are coated with a gelified polymer film composed of a mixture of polyvinylidene fluoride, 1-methyl-2-pyrrolidone, and 1-methyl-3-octylimidazolium hexafluorophosphate, which acts as a supporting electrolyte.

An additional advantage of this technology is its ability to efficiently and cost-effectively conduct preventive diagnostics of critical compounds without direct contact with the sample. This enables early detection of defects in wine and the implementation of corrective measures before they significantly impact product quality, providing an innovative and effective solution for the wine and food industry.

The research center is interested in contact with different partners. Commercial agreements are sought and partners for research cooperation agreements are welcome as well.
Advantages and Innovations
• Increased Analysis Efficiency and Sensitivity: The ability to simultaneously detect mercaptans and 4-ethylphenol in wines in the gas phase significantly improves analysis efficiency. Evaluating both critical compounds at the same time saves time and resources compared to traditional methods.

• Preserved Product Quality: Non-contact detection with the liquid sample is a key advantage, ensuring that the wine is not affected or contaminated during the analysis process. This is essential for preserving the quality and integrity of the final product.

• Early Diagnosis of Defects: The capability for routine and on-site analysis allows for early detection of defects in wines. This is crucial for taking corrective measures preventively and avoiding issues that may impact product quality.

• Cost-Efficient: The ability to conduct preventive diagnostics with minimal cost is a significant advantage. It enables wineries and food companies to control the quality of their products without incurring excessive expenses.

• Ease of Use: The capability for on-site analysis and the user-friendly nature of the technology makes it accessible for a wide range of users, from small wineries to large food companies.

This innovative electrochemical sensor technology, designed for simultaneous detection of mercaptans and 4-ethylphenol in wines, offers increased analysis efficiency and sensitivity. Utilizing dual-screen-printed carbon devices with electrode modification, it enhances conductivity and selectivity. The gas-phase detection method avoids direct contact with the wine sample, preserving product quality. Coated electrodes with a gelified polymer film enable cost-efficient preventive diagnostics, allowing early defect detection. Additionally, this device is characterized by its low cost, compact size, and user-friendly design. It has undergone laboratory testing with validated results and is now ready for commercialization.
