Separation Techniques Flashcards
True or false. The goal of analytical separation is to remove either the analyte or the interferent from the sample’s matrix
True
Identify the basis of separation of the following:
A. Filtration
B. Dialysis
C. Size-exclusion chromatography
Based on size
Identify the basis of separation of the following:
A. Distillation
B. Sublimation
C. Recrystallization
Based on change in physical state
Identify the basis of separation of the following:
A. Precipitation
B. Electrodeposition
C. Volatilization
Based on the change in chemical state
Identify the basis of separation of the following:
A. Extraction
B. Chromatography
Based on partitioning between phases
Identify the basis of separation of centrifugation
Based on mass and density
Separation technique based on size and charge
Electrophoresis
Separation technique that remives small unwanted compounds from macromolecules in solution by diffusion through a semi-permeable membrane
Dialysis
Separation technique that separates the component of liquid mixture through selective evaporation and condensation
Distillation
Separation technique that uses selective partitioning of the analyte between two immiscible phases
Extraction
Ratio of the solubility of the solute in the organic and aqueous phases
Partition coefficient
True or false. Large value of Kd indicates that extraction of solute into the aqueous phase is favorable.
False
Used to evaluate an extraction’s efficiency since the solute’s total concentration is considered in each phase
Distribution ratio
