A standard sample contains 15.0 mM of analyte and 25.0 mM of internal standard. The analysis of the standard sample gives peak areas for the analyte and internal standard of 1.782 and 3.539, respectively, in a chromatography analysis. Then sufficient internal standard is added to a sample to make its concentration 10.0 mM. The analysis of this new sample yields peak areas for the analyte and internal standard of 0.894 and 2.981, respectively. Name the calibration method and report the analyte's concentration in the new sample. (e)

A new method is proposed to simultaneously detectand separatefour foodadditives by reversed-phase liquid chromatography. The data were obtained using theliquid chromatographic column with a flow rate of 0.5 mL per min and with the followingparameters: Pore size 100 A Particle Size 3.5 Internal diameter 4.6 mm Length 150 mm The food additives found in the sample resulted in the following data: ( see image for table) a.Calculate the number of plates from each peak. b.Calculate the plate height for the column. c.Retention factor for each peak.
How can you ensure “good quality” peak separation in high performance liquid chromatography (HPLC)?
Chloroform is an internal standard in the determination of the pesticide DDT in a polarographic analysis in which each compound is reduced at an electrode surface. A mixture containing 0.500 mM chloroform and 0.800 mM DDT gave signals of 15.3 µA for chloroform and 10.1 µA for DDT. An unknown solution (10.00 mL) containing DDT was placed in a 100-ml volumetric flask and 10.2 ul of chloroform (MW = 119.39, density = 1.484 g/mL) were added. After dilution to the mark with solvent, polarographic signals of 29.4 and 8.7 µA were observed for the chloroform and DDT, respectively. Find the concentration of DDT in the unknown.
