Scan each sample 3 times resulting in approximately 120 scans (40 samples x 3 scans each sample). Examine the matrix via SCiO Lab to determine if the scatter plot is accurate or has wide variance.
To examine the matrix:
- Select the attribute you want the model to be analyzed by and click Create Model.
- The first image below shows a good model, where the scatter plot is accurate.
- The second image below shows a poor model. Use the toggle buttons to see the scans from different perspectives and help you discover your invalid records, pinpoint the variances and outliers and help you find the problems preventing success.
- SCiO Lab provides suggestions for improvement on every model. Follow those suggestions to improve your model, or contact us at dev@consumerphysics.com if you need help with your analysis.
Good Model
Poor Model
Once you have a working model, try creating and extending the model by introducing variations such a different temperatures and lighting. The more variation on a successful model, the stronger and more stable it will be for developing your future applications.
What Next?
Once feasibility is proven, the next step is to create a larger database of samples. Larger data collections result in more stable chemometric models.
Tip: Remember that your chemometric model can only ever be as good as your source data, both spectrum and metadata.
