Consider a solution containing 3.70 mM of an analyte, X, and 1.99 mM of a standard, S. Upon chromatographic separation of the solution peak areas for X and S are 3979 and 10035, respectively.
Determine the response factor for X relative to S.
F=?
To determine the concentration of X in an unknown solution, 1.00 mL of 8.42 mM S was added to 5.00 mL of the unknown X solution and the mixture was diluted to 10.0 mL. After chromatographic separation, this solution gave peak areas of 5737 and 4719 for X and S, respectively.
Determine the concentration of S in the 10.0 mL solution.
S=?mM
Determine the concentration of X in the 10.0 mL solution.
X=?mM
Determine the concentration of X in the unknown solution.
X=?mM
