Coulometric determination of sulphisomidine, sulphamethoxydiazine and sulphamoxole
(Journal of Pharmaceutical and Biomedical Analysis, 1991)
Predicting liquid chromatography−electrospray ionization/mass spectrometry signal from the structure of model compounds and experimental factors; case study of aripiprazole and its impurities
(Elsevier Inc., 2023)
A priori estimation of analyte response is crucial for the efficient development of liquid chromatography–electrospray ionization/mass spectrometry (LC–ESI/MS) methods, but remains a demanding task given the lack of knowledge ...
Analytical method development supported by DoE-DS approach for enantioseparation of (S,S)- and (R,R)-moxifloxacin
(Elsevier B.V., 2023)
In this paper, method for enantiomeric purity testing of fourth-generation fluoroquinolone, moxifloxacin hydrochloride, was developed and validated. Exceptional enantioselectivity for this assay was achieved using cyclodextrin ...
Fluorodensitometric determination of conjugated estrogens in raw material and in pharmaceutical preparations
(Elsevier, 1989)
A simple, rapid and reproducible fluorodensitometric method for the determination of conjugated estrogens has been developed. The proposed procedure includes the following steps: extraction, hydrolysis of sodium sulphate ...
Densitometric determination of metoprolol tartrate in pharmaceutical dosage forms
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
This paper describes a simple densitometric method for the determination of metroprolol tartrate in tablets and ampoules. After separation on silica gel GF254 plates, using acetone-methanol-triethylamine as the mobile phase ...
Quantitative analysis of analgoantipyretics in dosage form using planar chromatography
(Pergamon-Elsevier Science Ltd, Oxford, 2001)
In the therapy of pain of weaker genesis, frequently used drugs usually represent a mix of analgoantipyretics of different chemical structures, mostly derivatives of salicylic acid, pyrazolone and p-aminophenol as well as ...
Spectrophotometric determination of desoximetasone in ointment using 1,4-dihydrazinophthalazine
(Pergamon-Elsevier Science Ltd, Oxford, 1996)
The proposed method is based on coloured hydrazone formation with 1,4-dihydrazinophthalazine as a reagent. Heating at 85 degrees C for 2 h was found necessary to ensure optimal hydrazone formation in the presence of ...
Determination of anti-secalin antibodies in sera from coeliac patients by ELISA-based assay
(Elsevier, 1998)
Coeliac disease (CD) is a permanent intolerance
to dietary prolamins (alcohol soluble protein fraction of cereal gluten) from selected cereals (wheat,
rye, barley and oats) resulting in small intestinal
villus atrophy ...
