Abstract
The invention concerns a method which consists in performing for a time interval ranging between 1 ms and 10 ms a first turbidimetric measurement using a first light pulse originating from a first source (SL1) emitting in a first frequency range, a second measurement of intensity transmitted in response to a second light pulse originating from a second source (SL2) emitting in a second frequency range and, optionally determining the fluorescence of the sample. The invention is applicable to a biological analysis process as well as to hemostatic analyses.
