A band from a column eluted at 0.66 mL/min has a width at half-height, w1/2, of 39.6 s. The sample was applied as a sharp plug with a volume of 0.40 mL, and the detector volume is 0.25 mL. a. Find the variances introduced by injection and detection. b. What would w1/2 be if the only broadening occurred on the column?

A spectrophotometer method for the quantitative analysis of Pb2+ in blood uses Cu2+ as an internal standard. A standard containing 1.75 ppb Pb2+ and 2.25 ppb Cu2+ yields a signal of 0.832 for Pb2+ and a signal of 0.351 for Cu2+. A sample of blood is spiked with the same concentration of Cu2+, giving a signal of 0.520 for Pb2+ and 0.289 for Cu2+. Determine the concentration of Pb2+ in the sample of blood.
A third spectrophotometric method for the quantitative analysis of Pb2+ in blood uses Cu2+ as an internal standard. A standard containing 1.75 ppb Pb2+ and 2.25 ppb Cu2+ yields a ratio of (SA/SIS)std of 2.37. A sample of blood is spiked with the same concentration of Cu2+, giving a signal ratio, (SA/SIS)samp, of 1.80. Determine the concentration of Pb2+ in the sample of blood.

3 to the kit manual 200uL of plasma was mixed with 2.8 ml of the dilution buffer, mixed well then 200 uL of the dilution mixture was pipetted in 0.9 ml of solution A and 0.9 mL of solution B and measured using a spectrophotometer, the concentration was 30. What is the final concentration of the sample after adjusting the dilution factor
0.1120 g of a solid sample containing copper was dissolved by acid and transferred to a 250.00 mL volumetric flask and volume was made up with distilled water. The solution was then diluted by a factor of 25. The final solution was analyzed by atomic absorption spectrophotometry and the concentration was found be 2.982 ppm, What is the weight percentage of copper in the original solid sample? Keep four significant figures in your final answer.

A graphite furnace atomic absorption spectrophotometer (AAS) was used to determine the arsenic (As) concentrations in drinking water. A large set of blank samples yielded an average blank signal of 0.013 and a blank standard deviation of 0.0030. The following data were obtained for a calibration curve. [As] (ppm) 2.0 4.0 6.0 8.0 10.0 Absorbance 0.17 0.28 0.48 0.53 0.72 Using a spreadsheet on an Excell, create a graph of the data using symbols only for the data points. Plot the line on the same graph and include the graph to this question. (a). What is the sensitivity of the method? (b). Calculate the LOD and LOQ for As. (c). A sample of water yielded an absorbance of 0.43. What is the concentration of As in the water?
In a thin layer chromatography experiment, a plate of length 8.67 cm was used and a horizontal line was made at 1.11 cm above the bottom of the plate. After running the experiment (developing and drying), a spot was observed at 4.59 cm from the bottom of the plate, and the solvent front was 7.56 cm from the bottom of the plate. What is the Rf value?
