- What are the 5 important characteristics of spectrophotometric methodsWhat is the significance of the max of a spectrum? What are the other uses of the spectrophotometer?Label the graph with the correct axes for a standard curve used in a spectrophotometry experiment. y X Answer Bank Concentration (M) % Transmittance Sample # Absorbance Density (g/L)
- Identify and provide either an concise explanation of the concept signal-to-noise ratio (SNR), in the context of chemical analysis.A 600 MHz NMR has a signal to noise ratio of 1000 for a proton standard. The 400 MHz NMR has a signal to noise ratio of 200 for a proton standard. If it takes 20 minutes to get an acceptable signal to noise ratio for a sample on the 600 MHz NMR, how long will it take you to achieve the same signal to noise ratio on the 400 MHz NMR?The validation process comprises four main steps that are : hardware validation, software validation, method validation and system suitability. To evaluate a spectrophotometer’s accuracy by measuring absorbance, a solution of 60.06 mg/L K2Cr2O7 in 0.0050M H2SO4 was carefully prepared together with a 0.0050 M H2SO4 as a reagent blank. If the spectrometer’s signal is properly calibrated, it has been reported that this solution should provide an absorbance of 0.640 +- 0.010 at wavelength 350 nm. Which one of the validations mentioned above had been involved in this process? Explain your choice
- The standard graph contains absorbance values greater than 1.00 Is there a positive error, negative error, no effect, or error could not be determined In terms of the Linearity of the standard curve?A standard curve was performed using an Absorbance spectrophotometer, and the equation of that line was determined to be y = .1563x + .025. The absorbance of an unknown was measured at .35. Calculate the concentration of the unknown according to the standard curve.3. Fill in the following for the correspondence between % transmittance and absorbance: 100.0 % T = 0.0 absorbance 1.00 absorbance = (0.0 % T 25.0 % T = absorbance 0.25 absorbance = % T
- what parameters and quality control measures are needed in spectrophotometer?Compare and contrast Flame Emission Spectrophotometry and Atomic Absorption SpectrophotometrySuppose a student is preparing a set of standard solutions for use in a spectrophotometric study. If percent transmittance, %T, were measured in the standard solutions before the color had a chance to fully develop, the measured value would be compared with solutions that have allowed the color to fully develop.
