Chapter 8 Non-opioid analgesics
2008, Handbook of Analytical SeparationsCitation Excerpt :HPLC procedures are most often used for the analysis of paracetamol. Common C18 or C8 packing materials for LC columns have been most widely used and can be recommended for separation of paracetamol [4,10,11,19,23,36,59,93–108]. Isocratic or gradient elution procedures using acetonitrile or methanol/buffered water mixtures or mixtures of solvents (acetonitrile, hexane, isopropanol) with phosphate or acetate buffers resulted in sufficient separation.

2005, Analytica Chimica ActaCitation Excerpt :This drug produces a relatively high allergy and chemical intolerance [1]. Dipyrone has been determined by titrimetric [2], UV-spectrophotometric [3–5], colorometric [6], and polarographic [7] methods, high performance thin layer chromatography (HPTLC) [5], gas–liquid chromatography (GLC) [8] and liquid chromatography (LC) [9]. Reversed phase LC is the seperation method of choice for most pharmaceutial compounds both hydrophilic and hydrophobic, due to the stable and reproducible nature of the LC columns, the largely aqueous composition of mobile phases and relative ease of reproducing the methods in different laboratories.
