This approach is based on two optical methods: UV–vis spectrophotometry and laser granulometry. Heterogeneity of fractions, especially related to particle size, increases difficulty to perform an analytical approach over a large particle size scale. Methodology is developed on model mixtures in order to highlight limitations, either for a qualitative or a quantitative control, in so far as quantification efficiency could depend on mass transfer phenomena. %G English %2 https://imt-mines-ales.hal.science/hal-03181048/document %2 https://imt-mines-ales.hal.science/hal-03181048/file/study-of-heterogeneous-suspensions.pdf %L hal-03181048 %U https://imt-mines-ales.hal.science/hal-03181048 %~ INSTITUT-TELECOM %~ EM-ALES %~ AGROPOLIS %~ INSTITUTS-TELECOM
