Today I finished preparing my new calibration standards, as well as preparing another sample set. I am running the calibration standards for both the calibration and as a sample, so this should help me investigate how the calibration process is working. The new sample set should help to see if the calibration is helping to reduce the error. I am also trying to use a nonlinear fit for the calibration, to see if that helps. I am in the middle of analyzing the data now, but it is unclear whether I have been successful yet or not.
