FT-IR calibrations
For the calibration purpose, a data set of 18 paracetamol
standards ranging from 0.005 mg to 1 mg paracetamol in KBr were
prepared to formulate uniform pellet of 100 mg weight each time.
In order to formulate homogenous pellets and get reproducible
results same pressure was applied. Then all the standards spectra
of various concentrations in the above mentioned range were analyzed
in TQ Analyst program 7.3 (Thermo Electron) to develop
developing a calibration model using a straight line equation. Then
area under peak for all standard spectra was computed by selecting
specific region for the quantification of paracetamol in solid tablet
and capsules.
