RT Journal Article SR Electronic T1 Empirical Calibration of Light Blockage Sensors JF PDA Journal of Pharmaceutical Science and Technology JO PDA J Pharm Sci Technol FD Parenteral Drug Association (PDA) SP 9 OP 11 VO 46 IS 1 A1 Russell, A. W. YR 1992 UL http://journal.pda.org/content/46/1/9.abstract AB The intent of this note is to describe in more detail the calibration process for these sensors with particular emphasis on the method of obtaining the best calibration curve from the raw data. A new method of assessing the accuracy of the calibration curve is also described.
