Ensuring Laboratory-Grade Reliability
The CDR CoffeeLab® system utilizes advanced calibration curves developed through extensive analysis of both green and roasted coffee matrices. To ensure the utmost robustness of these measurements, systematic recovery tests were conducted, and comparative studies were performed involving the results obtained with CDR CoffeeLab®, the University of Florence, and independent external laboratories.
Furthermore, to validate the system's performance, the results were benchmarked against High-Performance Liquid Chromatography (HPLC), the industry standard for quantitative chemical analysis. This comparison demonstrates the reliability of the CDR CoffeeLab® as a rapid, on-site alternative to traditional, time-intensive chromatographic methods, offering laboratory-grade data with significantly increased efficiency.

Conclusion
The comparative analysis across all key parameters, Chlorogenic Acids, Malic Acid, Citric Acid, Lactic Acid, and Caffeine, demonstrates a high degree of correlation between the CDR CoffeeLab® system and the HPLC reference method.
The experimental data, collected from a diverse range of samples including Green Robusta, Green Arabica, and various roasted profiles, consistently show a high correlation coefficient (R2). The near-identity of the values obtained confirms that the CDR CoffeeLab® provides an analytical response perfectly aligned with traditional chromatography.
In conclusion, this study validates the CDR CoffeeLab® as a robust and reliable analytical tool. By delivering laboratory-grade accuracy through a simplified, user-friendly interface, it successfully bridges the gap between complex chemical analysis and the production floor. This makes high-level quality control accessible to non-specialized operators, allowing for rapid, informed decision-making throughout the coffee supply chain without the need for intensive training or sophisticated laboratory infrastructure
