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.

Q6. (a) Describe the differences between a linear TOF mass spectrometer and an orthogonal
TOF instrument? What are the advantages and limitations of these two geometries? *
(b) What function does the ICP torch have in ICPMS?
(c) Why has ICPMS become an important and widely used analytical method?

Expert Solution

Step 1

Time-of-flight (TOF) mass spectrometers are widely used for their high resolution and sensitivity. Linear TOF and orthogonal TOF are two different geometries of TOF mass spectrometers. Linear TOF has a linear flight tube, while orthogonal TOF has an orthogonal ion source and flight tube. The advantages and limitations of these two geometries depend on the specific applications and analytical goals.

Exactly 5.00 mL aliquots of a solution containing analyte X were transferred into 50.00-mL volumetric flasks and the pH of the solution is adjusted to 9.0. The following volumes of a standard solution containing 2.00 µg/mL of X were then added into each flask and the mixture was diluted to volume: 0.000, 0.500, 1.00, 1.50 and 2.00 mL. The fluorescence of each of these solutions was measured with a fluorometer, and the following values were obtained: 3.26, 4.80, 6.42, 8.02 and 9.56, respectively. ii. Using relevant functions in Excel, derive a least-squares equation for the data, and use the parameters of this equation to find the concentration of the phenobarbital in the unknown solution.

An impurity in water has an extinction coefficient of 3.45 * 103 M-1 cm-1 at 280 nm, its absorption maximum(A Closer Look, p. 576). Below 50 ppb, the impurity is not a problem for human health. Given that most spectrometers cannot detect absorbances less than 0.0001 with good reliability, is measuring the absorbance of a water sample at 280 nm a good way to detect concentrations of the impurity above the 50-ppb threshold?
