Yesterday we went to the TU Delft ChemLab, these results will be posted soon. But we also did some experiments with our own third prototype. We tested the fluids shown on the image below plus a control test:
We used a normal light bulb to send light through a sample into our spectrometer. Then we used online software to generate a result. The software can be found here: spectralworkbench.org/capture.
Below our results are shown:
Sweet white wine
Dry white wine
Some results are very clear, like Cassis & Sisi. Some results are not so clear, like Coke & Red wine. But most results can be very useful in differentiating between different fluids. Sometimes the differences are very slim, but they are there and that means you can test, at home, whether you have olive oil or sunflower oil in that unlabeled jar. And we think that is very interesting and also a lot of fun!
