2. Integration of Blood Plasma Separation and Reciprocation
Design and operation of the integrated CD (inset on the bottom demonstrate the orientation of the fluidic network on the CD). Sequence of process steps include: loading of the whole blood into the sample chamber; spin at 3800 rpm for 4 minutes to separate red blood cells into the RBC chamber from the plasma in the reciprocation chamber and air compression chamber; spin at 6000 rpm to compress the air in the air compression chamber; reduction of the angular velocity to 3800 rpm to push part of the plasma to the reciprocation chamber; repeated switching of the disc speed between 6000 rpm and 3800 rpm. Red color in the illustrations indicates the presence of red blood cells, while the gray color indicates plasma free from red blood cells.
