Before the final test, the team tested several concentrations to choose more accurate calibration curves. The second chip design was chosen for the final test because the calibration curves appeared more consistent than the first chip design. Below are the results of the preliminary testing, using three different calibration curves (noted by the dates of calibration). The binary values were recorded and converted to decimals. Then, the decimals were plugged into the calibration equations to find the concentration of fluorescein. The graph of the calibration curves can be found here.
Preliminary Test Results Using Second Chip
The second calibration curve was found to be the most accurate of both targets. However, the decimal readings were not very precise.
The team also conducted a preliminary test for the bonus chip. The calibration curves of this chip can be found here. The binary values were converted to decimals, and the concentrations were calculated using the calibration equations. Below are the results:
Preliminary Test using Bonus Chip
The concentration calculated using Trial 3 is the most accurate compared to other trials. Thus, this calibration curve is chosen for the final test.
