Consider that a single sample was analyzed using two different spectrometric instruments. One has 1.0% stray light at the assay wavelength, the other effectively no stray light. What relative error in the concentration would the 1.0% stray radiation cause if, on the better instrument, the samples had T= 0.40, T= 0.10, and T= 0.05? (This is another reason that in order to achieve the best precision, the middle absorbance range- A = 0.3 - 0.7-should be used if possible.)

An analyst needs to evaluate the potential effect of an interferent, I, on the quantitative analysis for an analyte, A. She begins by measuring the signal for a sample in which the interferent is absent and the analyte is present with a concentration of 15 ppm, obtaining an average signal of 23.3 (arbitrary units). When analyzing a sample in which the analyte is absent and the interferent is present with a concentration of 25 ppm, she obtains an average signal of 13.7. What is the sensitivity for the analyte? What is the sensitivity for the interfering? What is the value of the selectivity coefficient? What is the maximum concentration of interferent relative to that of the analyte (i.e. interferent/analyte), if the error in the analysis is to be less than 1%?
Derive the Scatchard equation for a reaction system 2P + X ↔ P2X, in which only P and P2X have measurable absorbances at the chosen wavelength. Based on this equation and the data given below, determine the values of Keq and ??2? (epsilon P2X).

The velocity selector in the problem prior to this one is used in a mass spectrometer. Protons(with zero neutrons) are the most common hydrogen nuclei. Some hydrogen isotopes, however, haveeither one or two neutrons in addition to the proton. If a beam of hydrogen nuclei is shot into amagnetic eld of strength 2.0T and the nuclei do a u-turn after which they strike a detector, how farapart will the three isotopes be on the detector surface? Assume both protons and neutrons have amass of 1:67 10?27kg and e = 1:60 10?19C.Cont.
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?
