Simple Beer’s law calibration model
Table 1 shows the response of the univariate simple Beer’s law
calibration model in different regions of the spectra by applying
different measurement criteria like peak height, peak area, baseline
correction either with two points or without baseline correction.
The results with peak height and peak area are comparable to
each other and are acceptable to same extent. The different regions
containing almost all the prominent bands were selected and
tested in TQ Analyst. The region 1800–1000 cm1 with two point
baseline correction and peak area was found to be the best region
for the accurate and precise recovery of up to 99.96% by using simple
Beer’s law model having linear regression (R2) 0.9994 as given
in Fig. 4.
