Analysis of cholesterol in mouse brain by HPLC with UV detection
(Public Library of Science, 2020-01)
We describe a sensitive high performance liquid chromatography (HPLC)-based method for the determination of cholesterol in brain tissue. The method does not require the derivatization of the analyte and uses separation and ...
Comparison of Impurity Profiles of Lipiblock (R) vs. Orlistat using HPLC and LC-MS/MS
(Colegio Farmaceuticos Provincia de Buenos Aires, 2012-02-01)
Comparative HPLC-UV and LC-MS/MS studies of impurity profiles of a reference sample (Xenical (R), F. Hoffmann La Roche Ltd., Switzerland) vs. generic (Lipiblock (R), EMS Sigma Pharma, a generic drug) were carried out with ...
CHEMICAL DEGRADATION OF ESFENVALERATE AND HPLC-UV-PAD DETECTION OF INTERMEDIATES AND BY-PRODUCTS
(TAYLOR & FRANCIS INCPHILADELPHIA, 2012)
The impact of pyretroids, their by-products and degradation products on humans and the environment is recognized as a serious problem. Despite several studies regarding esfenvalerate toxicity and its detection in water and ...
BIOEQUIVALENCE OF NORFLOXACIN BY HPLC-UV METHOD
(Sociedad Chilena de Química, 2010)
The Cramer’s rule for the parametrization of phenol and its hydroxylated byproducts: UV spectroscopy vs. high performance liquid chromatography
(Springer Science and Business Media Deutschland GmbH, 2020-10-02)
A linear algebra theorem like Cramer’s rule was used for the analysis of a system of equations obtained from UV spectroscopy, and results were compared against those obtained from HPLC analysis. This parametrization allowed ...
Comparison of Impurity Profiles of Lipiblock (R) vs. Orlistat using HPLC and LC-MS/MS
(Colegio Farmaceuticos Provincia de Buenos Aires, 2012-02-01)
Comparative HPLC-UV and LC-MS/MS studies of impurity profiles of a reference sample (Xenical (R), F. Hoffmann La Roche Ltd., Switzerland) vs. generic (Lipiblock (R), EMS Sigma Pharma, a generic drug) were carried out with ...
Absorbance detector for high performance liquid chromatography based on a deep-UV light-emitting diode at 235 nm
(2017-08-25)
In this communication, we describe a flow-through optical absorption detector for HPLC using for the first time a deep-UV light-emitting diode with an emission band at 235 nm as light source. The detector is also comprised ...
Voltammetric behaviour of ketorolac and its HPLC-EC determination in tablets
(Taylor and Francis Inc., 1997)
Ketorolac is an antiinflammatory-analgesic agent that is oxidizable at the glassy carbon electrode. The voltammetric oxidation produces two well resolved pH-dependent peaks, that are overlapped at pH>10. Using this ...
Dereplication of terpenes and phenolic compounds from Inga edulis extracts using HPLC-SPE-TT, RP-HPLC-PDA and NMR spectroscopy
(2020-01-01)
Inga edulis is traditionally used as anti-inflammatory and antidiarrheal and has been investigated as potential sources of biologically active natural products. In this study, dereplication strategy using HPLC-SPE-TT, ...
