Introduccion a La HPLC Quattrocchi

Sat Nov 30, 8: The method was applied to the determination of sulfamethazine in a veterinary commercial solution. Hello GuiHn If you are begining with hplc and you understand spanish I recommend: The solutions were protected from light with an aluminum foil wrapping and usually freshly prepared solutions were used.

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. Unknowns were applied as bands 3 times and references were applied as bands 2 times, each, and distribution of bands was done accordingly the data pair method.

Liquid-liquid extraction yields a good recovery of nifedipine from serum.

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. Nifedipine also may be used in the management of hypertension in patients with low-renin hypertension as black patientscoexisting angina, peripheral vascular-disease, or isolated systolic hypertension, and in geriatric patients.


Hashemi, Electroanalysis 24, Each solution was applied as bands 3 times. I’m sorry for my english, I’m Brazilian and I’m learning the language yet.

Karimi, Talanta And they are too old. For determination of nifedipine in blood, some methods using HPLC, voltammetry and spectrophotometry 39,40 have been reported. The volume of serum used was 2 mL. The analysis quattrochi fast, and the method allows a large number of samples to be measured simultaneously.

This range includes serum concentration found in literature 0.

Three replicates each were prepared and each replicate was applied as bands three times. Precision and accuracy Quality control samples spiked at three concentrations 0.

Standards used were at concentrations of 0. The migration distance was 8 cm and the migration time 12 min. Application of the method The nifedipine concentration ranged between 0.

A carbon paste electrode was modified with the ionic liquid 1-methyloctyl imidazolium hexafluorophosphate and it was applied for study the electrocatalytic oxidation and voltammetric determination of the drug sulfamethazine. In total there are 6 users online:: All chemicals and reagents were of analytical grade. Latest Blog Posts from Quattroccbi Science.


Working solutions were prepared at concentrations of 0. There is a list of some recommended books on our web site: Apologies for any authoring errors Inter-assay precision and inter-assay accuracy were calculated after repeated analysis in three different analytical runs.

The accuracy and precision did not exceed 4. The more common ways to evaluate the adherence of the patients with their medication are questionnaires about the daily administration of the drug, and pill counts, with the problem that the results can be true or false. Sun Mar 18, 1: This mixture was vortex-mixed for 1 min and then quattrocchj for 10 min at rpm. Med, The oxidation of sulfamethazine at the surface of intrduccion electrode occurs at lower potentials than that of an unmodified carbon paste electrode, and both an enhancement of the anodic peak current and a signal narrower and better defined with the modified electrode were observed.
