4. Conclusion
The use of a smart phone application was successfully applied to the analysis of colourimetric products to obtain analytical data for quantitative analysis. Methamphetamine concentrations in seized Yaba samples analyzed using this method showed very good correlations to accurate GC-FID data. This demonstrates a significant potential to develop an accurate, rapid, real-time, on-mobile quantitative test for the analysis of controlled substances.
