PHC 262: PHARMACEUTICAL ANALYTICAL CHEMISTRY‑II

(2 + 1)

 

 

Prereqisite:  PHC 261

 

Course Description

 

The course furnishes a broad basis for instrumental analysis which comprises, colorimetry, UV‑spectrophotometry, fluorometry, IR‑spectrometry, flame photometry, atomic absorption, spectrophotometry, polarimetry, refractometry, conductiometry and potentiometry. Furthermore, nuclear magnetic resonance (NMR), mass‑spectrometry and high‑performance liquid chromatography (HPLC) will be briefly introduced.
