Which of the following statements is less appropriate to consider when conducting bioanalysis?
The presence of other compounds that are also identified due to structural similarity
Using a standard reference of the active pharmaceutical ingredient in a formulation to analyze the concentration of a prodrug's metabolite
The decomposition of the drug in the sample due to enzymatic reactions
The hydrolysis process of conjugated drug forms during metabolism
Most synthetic drugs exist in racemic form
Sample preparation for bioanalysis is an important step due to several aspects below, except:
Eliminating the potential interfering components from the sample matrix
obtaining more accurate results
Concentrating the sample to enable detection
Protecting the analytical instrument from potential damage
Speeding up the detection process of the components to be analyzed
The following statements are correct regarding the accelerated solvent extraction technique in bioanalysis, except
Using a small amount of solvent
Can be used for solid and semi-solid biological samples
Minimizes sample exposure to solvents
Uses Soxhlet extraction or sonication in the process
Utilizes heating with an oven
The following statements are consistent with ion exchange separation techniques for bioanalysis, except:
The bond between the analyte and the sorbent is weak, making it easy to be eluted
pH changes can be used in the separation process
Analysis is based on the interaction between the sorbent and the sample in a solution with different charges
Hydrophobic contaminants can be removed using an organic solvent
The analyte to be analyzed must be in its ionic form
The following are types of sorbents commonly used in ion-exchange chromatography:
1.aminopropyl
2.sulfonic acid
3.diethylamino
4.carboxylic acid
5.cellulose
Which one can be used for cation-exchange chromatography in bioanalysis?
1 and 2
3 and 4
1 and 5
4 and 5
2 and 4
The interactions between the sorbent in SPE and the analyte commonly found are as follows, except:
van der Waals force
hydrogen bond
electrostatic attraction
polar interaction
covalent bond
