Portable water activity measurement for low water content samples
A portable water activity measurement system utilizing a USB-connected probe for rapid and accurate determination of water content in small biological and environmental samples, ideal for low water content measurements.
Overview
This innovative solution offers a portable water activity measurement system designed to quickly and accurately determine the water content in small biological and environmental samples. Utilizing a USB-connected probe, this system is especially valuable for low water content samples, providing rapid assessments from a minimal quantity. It is particularly useful in fields such as microbiology and food sciences, where understanding the desiccation level of a sample is crucial.
Technical specifications
- Portable measurement system: Utilizes a small chamber that can be temperature controlled or operated at room temperature.
- USB-connected probe: Connects easily to a PC or laptop, facilitating direct data collection and analysis.
- Sample size flexibility: Capable of measuring samples as small as a few grams to approximately one hundred milligrams.
- Measurement range: Delivers water activity readings from 0 (completely dry) to 1 (fully saturated), allowing for precise moisture content analysis.
Technology readiness level
This technology is currently at TRL 4, indicating that it has been validated in a laboratory setting. Future validation involves further testing with specific sample types, such as potato samples, to confirm its applicability in real-world scenarios.
