Statistics, morphology, abundance - using an internal reference

3 Statistics, morphology, abundance - using an internal reference 

Twenty representative samples from two manufacturers were placed in a matrix, along with three pure component samples, resulting in a sample area of 9 x 7 cm2. The optics were configured so that each of the 81 920 pixels measures an area of 275 x 275. im2, and data from the entire sample matrix can be collected simultaneously. Data were collected from 1100 to 2450 nm at 10 nm increments with 16 frames coadded at each wavelength and take 5 min to acquire. 

The results show that group A abundance estimates more closely track the values reported on the label, whereas the group B estimations are further from reported values. Because the individual tablets comprise a single dataset, this difference is not due to experimental or data processing anomalies, as the data were 

Summarizing the information across tablet groups enables the overall blend uniformity between samples A and B to be compared, and these results are presented in Table 2.4. 

The results show that the acetaminophen and aspirin components for group A are relatively homogeneous when compared with the caffeine values for these tablets.
