Norepinephrine can be analyzed in human urine. A fixed amount of DHBA was added to each sample and standard in a fixed concentration. Please explain the analytical function of adding DHBA. To the 1 mL of urine sample, small amounts of 1 µg/mL norepinephrine standard is added and the following results were obtained. What is the concentration of the norepinephrine in the urine sample with uncertainty?
Glucose levels are routinely monitored in patients suffering from diabetes. The glucose concentrations in a patient with mildly elevated glucose levels were determined in different months by a spectrophotometric analytical method.

In replicate analyses, the carbohydrate content of a glycoprotein (a protein with sugars attached to it) is found to be 12.6, 11.9, 13.0, 12.7, and 12.5 g of carbohydrate per 100 g of protein. (a) Find the mean of the measurements. (b) Find the standard deviation (s). (c) Find the 90% confidence intervals for the carbohydrate content. (d) If the mean and s are unchanged, but there are 10 measurements (N=10) instead of 5, what would be the confidence interval? (e) How does increasing the number of replicate measurements affect the reliability of measurements? Explain your answer. (Hint: better precision gives smaller confidence intervals)

In the technique of high performance liquid chromatography (HPLC) the peak area response for a particular analyte is directly proportional to concentration Analgesic tablets typically consist of aspirin and caffeine as the active ingredients, the remainder made up of inert binding material. The concentrations of aspirin and caffeine may be routinely monitored using HPLC, whereby the peak areas obtained from a solution of the tablet are compared with those obtained from standard solutions of the analytes. In an analysis to determine the concentration of caffeine in such a tablet, the following data were recorded: Solutions Analysed: Tablet Sample: Mass of tablet (dissolved in 250 cm methano): 0.523 g Caffeine Standard: Mass of caffeine (diessolved in 500 cm methanol) 0.105 g HPLC results: Solution Peak Area (catfeine) 1.
