State the analysis wavelength

15. Suppose that you are a QC technician working for Ocean Spray Corporation and you were asked to determine the concentration of iron in 100\% apple juice using ICP-OES and multipoint internal standard method. The current nutritional label on the juice bottles being shipped to grocery stores for iron states 250mg/10floz. Answer the questions below ensuring that you footnote and reference all sources used. a. State the analysis wavelength that you should use such that the other analyte elements do not spectrally interfer. mass of primary standard grade (NH4)2Fe(SO4)2(H2O)6 that you would need to weigh. c. Calculate the Fe2+ concentration in ppm that is stated on the apple juice label. d. Assuming that you need to make a 2/25 dilution of the juice sample for ICP-OES analysis of iron using the information from part c., calculate the Fe2+ concentration in ppm for this dilution. e. Based on the diluted Fe2+ concentration for juice sample in part d., STATE an appropriate concentration range (LDR) that you would use when preparing calibration standards for the analysis of iron. Assume that the LOL is 100.00ppm for potassium. E XP T 117 f. Assuming that you are preparing 5Fe2+ calibration standard solutions directly from the 1000.0 highest calibration standards using 50.00mL volumetric flasks. Show the two calculations. List the other 3 volumes in a table along with the two calculated volumes and corresponding concentrations in the same table
