Which of the following statements are true for chemical interference?
I Releasing agents are added to the sample to reduce chemical interference.
II Chemical interference occurs when a component of the sample reduces the extent of atomization of the analyte.
III Higher temperature flames will reduce chemical interference.
IV Chemical interference occurs when a component of the sample emits light at or close to the same frequency as the analyte.
V Releasing agents will preferentially react with the analyte,protecting the analyte from components of the sample that will ionize the analyte.
A)III,IV,and V
B)I,III,and IV
C)I,II,and IV
D)I,II,and III
E)II,III,and V

Question

Quizplus · Accepted Answer

I, II, and III are true statements regarding chemical interference. Releasing agents are indeed added to reduce chemical interference by reacting with interfering substances. Chemical interference can occur when a sample component reduces atomization of the analyte, and higher temperature flames can help reduce such interference by promoting more complete atomization. Statement IV is incorrect because it describes spectral interference, not chemical interference. Statement V is incorrect in its description of the role of releasing agents; they do not protect the analyte but rather bind with interfering agents.
