-What is your rough estimation of the concentration if you determine the absorbance
of a sample is 0.150?
Absorbance
1.0 ml of serum albumin (BSA) solution was precisely diluted to 100 ml with a buffer solution, and the absorbance at 280 nm was measured from this buffer solution at a distance of 1 cm from the light. The result was A=1.0. BSA is 0.1%(=0.1g/l). The absorptivity is e(0.1%)=0.667, so 1g/l solution gives an absorbance of 0.667.
What was the original protein content? Report in the result unit mg/ml with an accuracy of 0.1 mg.
In the spectrofluorometric analysis of quinine, which of the following statements/phrases can be considered a factor level?
A. Concentration of 2 ppm of iodide
B. Concentration of quenchers
C. The use of iodide
