Evaluation of portable Raman instrumentation for identification of beta-carotene and mellitic acid in two-component mixtures with halite
Original language description
Here we present the results of the analysis of halite/beta-carotene and halite/mellitic acid mixtures, performed by miniaturized Raman instrumentation equipped with 785 and 1064nm excitation. Various proportions of organics in the halite matrix were examined. The lowest concentration of beta-carotene detected using the 785 nm laser was 1 mg kg(-1), with slightly better signals observed with shorter exposure times compared with the bench instrument using the same excitation wavelength. Mellitic acid wasidentified at the concentration level 10 g kg(-1). The 1064 nm excitation provided a lower sensitivity towards low concentration when compared with the 785 nm excitation.
