You run the chromatography system with paper as the stationary phase and 70% isopropanol as the mobile phase. You determine the Rf  of a polar analyte to be 0.40. If you use 100% isopropanol (a less polar solvent) instead of isopropanol as the mobile phase what would you expect to happen to the Rf  value? No value effect on Rf higher  lower could be higher or lower

11. Order: Ticar (ticarcillin disodium) 1 g IVPB q6h, infuse in 50 mL D5W over 45 minutes. The instructions for the 1 g vial state to reconstitute with 2 mL of sterile water for injection yielding 1g/2.6 mL. At what rate in mL/h will you set the pump?

You obtained the following raw data when setting up a Bradford standard curve: BSA (mg/ml) Absorbancy 595nm 0 0.155 1 0.287 2 0.420 3 0.523 4 0.651 5 0.756 6 0.878 7 0.918 8 0.954 9 10 0.982 0.990 After blanking against a bradford-dH2O sample, the protein concentration of an unknown sample was determined using the same method and an absorbancy of 0.566 was obtained. Set up a standard curve, excluding outliers (experimental and statistical) and determine the protein concentration in the unknown sample in mg/ml (up to 3 decimal places).
