An echelle monochromator is typically used for atomic emission spectroscopy. What are the two main reasons for this?
Homework Answers
- The main reason for this is that the earlier models had a very low throughput, of f/10 – f/12. However, with changes in echelle designs, f/6 and lower are also now available.
- Given their ability to capture large bandpass spectral coverage of approximately 750nm and simultaneously provide high resolution of 0.04nm (at 200nm).
- Theses can prove to be extremely handy and flexible tools for varied types of spectroscopy research in laboratories.

Would atomic emission spectroscopy be a useful technique for determining the oxidation state of arsenic in a water sample? Why or why not? (Bonus, what would an analyst have to do to determine oxidation state? (otherwise referred to as "speciation")) List two reasons why the excitation bandwidth using a hollow cathode lamp is much narrower than the emission bandwidth for atomic spectroscopy? Use an equation in your answer (hint, think Doppler).

Atomic emission spectroscopy and the method of standard addition are used to determine the Nat concentration and its uncertainty in an unknown sample. Increasing amounts of a 1.75 μg/m standard Na+ solution are added to a series of volumetric flasks containing 15.00 mL of the unknown 200.0 mL. Atomic emission spectroscopy is then used to measure the emission intensity of each solution. solution. The volumetric flasks are then diluted to a final volume of Unknown volume Standard volume Final volume...

25 mL of a serum sample is to be analyzed by atomic emission spectroscopy for silver (Ag) metal. After thorough mixing, a student transferred 2.5 mL of this serum sample to a 100 mL volumetric flask followed by the addition of 10 mL 0.5 M sulfuric acid to the sample. He then diluted it to volume in the volumetric flask with deionized water. After setting up his...

The emission line used for zinc determinations in atomic emissionspectroscopy is 214 nm. If there are 6.00×1010atoms of zinc emitting light in the instrument flame at any giveninstant, what energy (in joules) must the flame continuously supplyto achieve this level of emission? (Answer must be inJoules)
