TY - JOUR T1 - Empirical Calibration of Light Blockage Sensors JF - PDA Journal of Pharmaceutical Science and Technology JO - PDA J Pharm Sci Technol SP - 9 LP - 11 VL - 46 IS - 1 AU - A. W. Russell Y1 - 1992/01/01 UR - http://journal.pda.org/content/46/1/9.abstract N2 - 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. ER -
