WebApr 4, 2024 · Together with bioavailability (F), the mean absorption time (MAT) can be used to define the rate of bioavailability, i.e., the rate of drug absorption. Previous results suggest that F may depend on MAT. Estimates of F and MAT were obtained from the input function (sum of two inverse Gaussian functions) used to model the oral absorption process. http://www.u.arizona.edu/%7Egwatts/azcc/InterpretingSpec.pdf
WebYou can derive this equation from Beer's law (Absorbance = e L c) C 1 / C 2 = A 1 / A 2 (ONLY for absorbances that are measured/predicted at the SAME Wavelength) Therefore, C 1 = (A 1 / A 2) * C 2 Substitute all the values as follow: A 1 = 0.37; A 2 = 0.43 & C 2 =0.14M Thus, C 1 = 0.12M Graphing Example Web1 Frequency distribution and mean comparisons of red light absorbance-transmittance of the e1 leaf sectors of five pipeline maize hybrids during early grain filling in subtropical winter Precision of chlorophyll meter measures Nav Raj Adhikari1*, Surya K.
