Preparation of Simulated Blood Plasma
Draw a small amount of yellow food coloring into a Pasteur pipette and squirt it out again. Rinse the pipette with deionized water and dilute the rinsings to about 10 mL. Add a few drops of this colored solution to the volumetric flask, in which the analyte sample is being prepared, to approximate the pale yellow color of blood plasma.
