The present invention discloses a device and a rapid nondestructive methodology for the detection and quantification of components from their binary mixtures (e.g. methanol-ethanol). The developed device acquires the in-elastically scattered photons from the sample and predicts the concentration of a component in the mixture through data processing and analysis as sequenced in the algorithm. In particular, the device can automatically predict the relative percentage of the components in binary mixtures. The analysis methodology includes a unique mathematical model based on the characteristic peak intensity/area ratios of components present in the binary mixture. Algorithm for determining the component concentration in mixture has been developed to analyse and implement in a mathematical model for automatically predicting the composition.
