Dong, Talanta 76, Detection and quantification limits Serum spiked with nifedipine standard to obtain concentrations of 0. Liquid-liquid extraction yields a good recovery of nifedipine from serum.
Mon May 16, 8: High performance thin layer chromatography HPTLC is a technique carried out within a short period of time, as allows for the analysis of a large number of samples simultaneously. Quattroccgi Mar 18, 1: GentlemanCologne best place on net for men’s cologone.
Best luck Mucha suerte Fernando. Iowa State University Press, Densitometry readings were carried out using the Camag system described before, and with a deuterium lamp as the radiation source. Chromatography Chromatography was carried out on HPTLC glass backed plates 10 x 10 cm and 20 x 10 cm precoated with silica gel Flayer thickness 0.

Med, Nifedipine is a 1, 4-dyhydropiridine-derivative calcium-channel blocking agent Figure 1. Nifedipine is used alone or in combination with other classes of antihypertensive agents in the management of hypertension.
Both accuracy and precision values were very acceptable, and the peaks of nifedipine and of the internal standard carbamazepine were well resolved.
Application of the method. Therefore, the principal advantage of HPTLC is a fast analysis, with a high selectivity, accuracy, sensitivity nanograms in UV absorbance mode and picograms in fluorescence mode and precision.
Chromatographic chambers were previously saturated with solvent mixture for 20 min. But, I will read this book too, thanks. And they are too old. Bioanalytical Method Validation, U. No other method using HPTLC was found in the literature, for the quantification of nifedipine in human serum neither in human plasma.
Six patient volunteers who were using nifedipine mg once daily as treatment for hypertension participated in this study. Inter-assay precision and inter-assay accuracy were calculated after repeated quattorcchi in three different analytical runs.

No registered users and 6 guests. Each solution was applied as bands 3 times. Thank you guys, I’ll try to find them to buy, here in Brazil we do not have many options, only a couple of books by local authors, but they treat the basics only. Selectivity The selectivity of the method was examined by preparing and analyzing checked by analyzing human serum samples spiked with nifedipine and the internal standard carbamazepine.
Application of the method The nifedipine concentration quattroccchi between 0.
Is an excellent book for beginners, the only drawback is that is rather old. Antimicrobial therapy in veterinary medicine, 2nd qhattrocchi. Separation Science offers free learning from the experts covering methods, applications, webinars, eSeminars, videos, tutorials for users of liquid chromatography, gas chromatography, mass spectrometry, sample preparation and related analytical techniques.
Chailapakul, Talanta 79, Tue Aug 17, 7: The sampling was carried out under extremely subdued light and all tubes and syringes were wrapped in aluminum foil because of the photolability of nifedipine. Resolution R S between both peaks was 3. intrlduccion
High performance thin layer chromatographic determination of nifedipine in human serum after liquid-liquid extraction. Standards used were at concentrations of 0. Acta6 This mixture was vortex-mixed for 1 min and then centrifuged for 10 min at rpm.
