Chromatographic assays

Exchanges between pharmacopoeias are co-ordinated by the Pharmacopoeial Discussion Group (PDG) (International Harmonisation 1995) and it is frequent that one pharmacopoeia participates in a collaborative study organized by another pharmacopoeia, or that several pharmacopoeias share the same batch of reference substance to be used in their respective monographs nevertheless, in this case the reference substance can not be considered as harmonized. A new batch of erythromycin was shared between the United States Pharmacopoeia and the European Pharmacopoeia and was established in a common coEaborative study both for the microbiological assay (used in the USP for formulations) and the liquid chromatographic assay (used in the Ph. Eur. and USP for bulk material). [Pg.192]

A gas liquid chromatographic assay for determining the quantity and composition of fatty acids is based on conversion of the acids by means of CDI with methanol, ethanol, trifluoroethanol, pentafluoropropanol, or heptafluorobutanol into the corresponding esters. The alcohols in question were chosen because of the short retention times of their esters.1333... [Pg.413]

Rajagopalan et al. [72] described an electron-capture gas chromatographic assay method for the determination of primaquine in blood. The method involves deriva-tization with heptafluorobutyric anhydride to form the diheptafluorobutyramide derivative after a single extraction at alkaline pH. The derivatives are quantitated by electron-capture gas chromatography. Blood levels of primaquine as low as 8 ng/mL can be measured with good precision. [Pg.187]

Today, most modern data systems provide a comprehensive array of quantitation methodologies. In general, chromatographic peaks may be quantitated using area, height, % area, and % height. Within these basic techniques, the chromatographic assay may also require the use of an Internal Standard to help correct for injector variability or sample-prep... [Pg.587]
