About the SAT

The Smartphone-based Analysis Assessment Tool (SAT) is a structured, 100-point rubric for objectively evaluating analytical methods that rely on smartphone imaging. It converts qualitative judgements into a transparent, comparable score.

The four scoring categories

• Imaging Standardization (30 pts) — imaging box, white balance, imaging distance, lighting conditions and region selection.
• Analytical Performance (40 pts) — LOD, LOQ, recovery, precision (RSD%), linearity (R²) and statistical comparison with a reference method.
• Practical Applicability (20 pts) — sample size, analysis time, cost and real-sample application.
• Accessibility (10 pts) — availability of the analysis software.

How the grade is assigned

• 85 – 100: Excellent
• 70 – 84: Good
• 50 – 69: Acceptable
• Below 50: Poor
