Application of the response surface methodology for RP-HPLC analysis of lidocaine and cetrimonium bromide: [PDF]

, 2004
The successful analysis of drugs in complex pharmaceutical formulations by reversed-phase high performance liquid chromatography (RP-HPLC) relies upon the optimization of the chromatographic conditions, the sample preparation and post-column detection. HPLC separation of mixtures depends on a large number of factors.

Controlling foodborne pathogens in irrigation water: the effectiveness of zeolite modified with cetrimonium bromide [PDF]

Revista Facultad Nacional de Agronomía Medellín
Recurring foodborne outbreaks, attributed to Escherichia coli O157:H7, Salmonella sp., and Listeria monocytogenes, have identified irrigation water as a potential source of contamination, and creating the necessity for safe irrigation water in produce cultivation, as emphasized by the Food Safety Modernization Act (FSMA). In response to this imperative,
