Q 2.2 Detectors used for quantitation with the HPLC method include electron capture and flame ionization.
False - GLC detectors
Q 2.3 The EMIT assay method involves quantitation using the measurement of radioactivity associated with the bound drug fraction.
False - Enzyme Reaction
Q 2.4 The point-slope method can be used to numerically integrate differential equations.
True
Q 2.5 The Laplace transform technique can be used to numerically integrate differential equations.
False - Analytical Integration
Q 2.6 The Laplace of a constant is the constant divided by s.
True
Q 2.7 Boomer can be used to calculate concentration versus time data using given parameter values or to find best values for parameters.
True
Q 2.8 When a substance emits light by fluorescence it is usually at the same wavelength as the excitation wavelength.
False - Wavelength is higher (lower energy)
Q 2.9 Spreadsheets are useful for calculating and graphing various equations related to pharmacokinetics.
True
Q 2.10 UV-visible absorption spectra exhibit sharp peaks because the absorption of light involves only electronic transitions and no transfer of energy via rotation or vibration.
False - broad peaks because of rotation and vibration
