Document Summary
Chmb16fall2012 lecture 5: quality assurance and calibrating methods (chapter 5) False results: false positive: false result is higher/greater than actual value, false negative: false result is lower than actual value. Should not give you a result, but if it does then once again it is due to interference. Spike recovery: also called fortification recovery refers to the addition of known concentration of analyte to the solution, whether the percentage of recovery is acceptable or not depends on what is listed as acceptable in your specifications. Because eliminated matrix effects: matrix: everything in the unknown except the analyte, matrix effect: a change in what is being measured caused by something in the sample that is not the analyte. 2021o you can then use that formula to calculate unknown concentrations. Q-test: detection of gross errors: note: in exams, he will say whether to use g test or q test g test is usually.
