Inductively coupled plasma-optical emission spectroscopy (ICP-OES) is a quantitative method fordetermining trace elements in liquid samples. ICP-OES and other methods of spectrochemicalanalysis are typically subject to errors due to the present of interferences. It had been reported thatICP-OES is significantly affected by spectral interference, but relatively less affected by thechemical interferences.(111)When analyzing Pb by utilizing ICP-OES, the presence of coexisting elements in thesample solution may lead to the ionization interference. Do you think the use of thefollowing elements: Cs, Na, and Ba can minimize the ionization interference caused by thecoexisting elements? Explain. Given that the first ionization energies for these elementsare: Cs (3.89 eV), Na (5.14 eV), Ba (5.21 eV), Pb (7.41 eV), respectively.

5.4.5 Chemical microanalysis5.4.5.1 Exploitation of characteristic X-raysElectron probe microanalysis (EPMA) of bulk samples is now a routine technique for obtaining rapid, accurate analysis of alloys. A small electron probe (100 nm diameter) is used to generate X-rays from a defined area of a polished specimen and the intensity of the various characteristic X-rays measured usingeither wavelength-dispersive spectrometers (WDS) or energy-dispersive spectrometers (EDS). Typically the accuracy of the analysis is š0.1%. One of the limitations of EPMA of bulk samples is that the volume of the sample which contributes to the X-ray signal is relatively independent of the size of theelectron probe, because high-angle elastic scattering of electrons within the sample generates X-rays. The consequence of this is that the spatial resolution of EPMA is no better than ¾2 µm. In the last few years EDX detectors have been interfaced totransmission electron microscopes which are capable of operating…
Explain why an internal standard is required during sample preparation in quantitative analysis when using atomic spectroscopy?
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
One dietary supplement capsule weighing 4.90 was ground into a fine powder. Two portions of the solid, both weighing 0.200 g, were dissolved in dilute acid, and transferred to 50-mL volumetric flask. To one of these, 5.00 mL of 40.0 ppm manganese ion was added, then both flasks were diluted to the mark with distilled water. When aspirated into the flame of an atomic absorption spectrometer set at a manganese absorption wavelength, the absorbances of the unknown and unknown plus standard were 0.300 and 0.650, respectively. What is the type of calibration method used? a) Standard Addition b) Internal Standard c) External Standard
Instrumental studies involve the calculation of the instruments' limit of detection (LOD) in addition to the calibration curve. a. What exactly is LOD? b. Why is it necessary to determine it? c. Hpw is it determined?
