Question 7 Which of the following statements is true regarding liquid liquid extraction for sample's preparation. O In liquid liquid extraction, the analyte is separated from the sample matrix using a chromatography stationary phase. The analyte sticks to the column and the water wash removes all species that do not adhere to the column. O Two solvents differe in their polarities are used where the analyte is extracted into the similar (close in polarity) solvent. The solid and liquid phase heterogenous mixture is centrefuged prior to sample measurement and analysis.
For quantitative analysis with gas chromatography: O the area of a peak reported by the instrument for a compound is proportional to the quantity of that compound.
