Spectroanalytical Methods

Spectroanalytical methods measure the wavelength and intensity of radiations that are either emitted or absorbed by a molecular or atomic species. These methods are useful for evaluating the electronic or atomic arrangement of the molecules of a given analyte.

Inductively coupled plasma–optical emission spectrometry (ICP-OES) was used for the determination of cadmium using indium as an internal standard. A solution containing 2.15 ppm Cd2+ and 5.76 ppm In3+ gave signals of 19,291 and 37,190 counts for cadmium and indium, respectively. A 0.01652 g sample was dissolved in acid and quantitatively transferred to a 250.0 mL volumetric flask. A 1.00 mL aliquot of 264.5 ppm In3+ was added and the flask was diluted to volume with deionized water. ICP-OES analysis of the sample solution gave signals of 31,109 and 118,941 counts for cadmium and indium, respectively. What was concentration of the Cd2+ in the sample? Give answer all questions with explanation

A. a conventional mass spectrometer does not use a spectrophotometric detectorB. a conventional mass spectrometer does not always require high purity samplesC. a mass spectrum shows no signals due to uncharged speciesD. a conventional mass spectrometer uses high energy UV radiation
In the determination of Pb in a contaminated fishmeal, 5.08 g of sample was weighed. Digestion with acids was applied and brought to dryness. Then it was made up to 10 mL and the absorbance was measured, obtaining a value of 0.013. The concentrations of the calibration curve made in ug/L are: 0.011; 0.022; 0.042 and 0.084 and the absorbances are: 0.001; 0.004; 0.009 and 0.020. Calculate the concentration of Pb in the sample in ug/kg and the % of Pb in the fishmeal.
Quinine in a 1.553-g antimalarial tablet was dissolved in sufficient 0.10 M HCl to give 250 mL of solution.A 10.00-mL aliquot was then diluted to 50.00 mL with the acid. The fluorescence intensity for the dilutedsample at 347.5 nm provided a reading of 196 on an arbitrary scale. A standard 100-ppm quinine solutionregistered 125 when measured under conditions identical to those for the diluted sample. Calculate the massin milligrams of quinine in the tablet.
