Interpretation:
The ICP plasmas should be compared to microwave plasmas with respect to their advantages and disadvantages.
Concept introduction:
ICP plasmas or Inductively Coupled Plasmas are a high-temperature source of ion and they ionize, atomize, and decompose the samples. It uses inductively coupled plasmas to produce or form excited ions and atoms which help in emitting
Plasmas generated by microwave are known as microwave plasmas. The magnetrons which generate plasmas are settled outside the plasma. With the help of quartz window, the radiation gets irradiated into the vacuum chamber.

Principles of Instrumental Analysis
- Provide brief definitions of fluorescence and phosphorescence, with aid of a Jablonski diagram.arrow_forwardA Knudsen cell was used to determine the vapour pressure of germanium at 1000 °C. During an interval of 7200 s the mass loss through a hole of radius 0.50 mm amounted to 43 μg. What is the vapour pressure of germanium at 1000 °C? Assume the gas to be monatomic.arrow_forwardUse the Jablonski diagram to explain why the narrower the band-gap is, the lower the fluorescence efficiency(fluorescence quantum efficiency) in general.arrow_forward
- Discuss the differences between fluorescence and phosphorescence. Draw the jablonski energy diagram. Explain about intersystem crossing and quenching of fluorescence.arrow_forwardAnswer with stepsarrow_forwardUnder what conditions does the extended Debye-Huckel law, equation 8.52, become the Debye-Hckel limiting law?arrow_forward
- Discuss how X-rays suitable for macromolecular studies are generated “in-house”. What are the advantages of using synchrotron radiation for macromolecular studies?arrow_forwardHow is the behavior in general regarding the absorption and emission spectra of fluorescence and phosphorescence?arrow_forwardWhy can UV or higher energy radiation not be used for non-destructive spectroscopy of polymer structure ? Why is resolution limited by wavelength?arrow_forward
- It is observed that the critical micelle concentration of sodium dodecyl sulfate in aqueous solution decreases as the concentration of added sodium chlordie increases. Explain this effect.arrow_forward16.2 Consider 1.00 x 1022 4He atoms in a box of dimensions 1.0 cm x 1.0 cm x 1.0 cm. Calculate the occupancy of the first excited level at 1.0 mK, 2.0 K, and 4.0 K. Do the same for ³He. What conclusions might you draw from the results of your calculations?arrow_forwardCovalent bonds in a molecule absorb radiation in the IR region and vibrate at characteristic frequencies. Note: Reference the Fundamental constants and Unit conversions for derived SI units tables for additional information, Part 1 of 2 A molecular vibration absorbs radiation of wavelength 219. um. What frequency corresponds to that wavelength? Round your answer to 3 significant figures. 0.9 X G Part 2 of 2 A molecular vibration has a frequency of vibration of 9,490x 10 Hz.
