Explain chromatographic analysis

Reference no: EM13273582

A solution containing 3.45 mM of p-xylene (analyte) and 6.86 mM of nonane (standard) gave peak areas of 13587 and 14769 respectively, in a chromatographic analysis. then 1.5 mL of 6.86mM nonane solution was added to 5 mL of an unknown sample containing p-xylene. This solution gave peak areas of11875 and 10765 for p-xylene and nonane.

(A)calculate the response factor for the analyte.

(B)find the concentration of the standard (mM) in the mixed solution

(D) find the concentration of p-xylene in the original unknown sample
