Glyphosate is widely used in herbicides and is toxic to organism. Therefore accurate detection of glyphosate content is important for public health and food security. In this paper, methods such as gas chromatography (GC), high performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC/MS), liquid chromatography-mass spectrometry (LC/MS), ion chromatography (IC), capilla...

conclusions this method could be feasibly used for purification of large quantities of allicin from garlic extract. results semi-preparative hplc yielded a distinct peak with a retention time of 12.28 minutes. the purity (≥ 95%) and biological activity (p > 0.05) of purified allicin were comparable to the standard allicin. purified allicin produced same peak areas compared to the standard allic...

High-temperature liquid chromatography (HTLC) is recognized today as a valuable technique in reversed-phase high-performance liquid chromatography (RP-HPLC). Column temperature can play a role in reducing analysis time, modifying retention, controlling selectivity, changing efficiency or improving detection sensitivity. The different effects of high temperatures on reversed-phase separations, t...

Determination of duloxetine by various methods from various matrices is reviewed in this paper. The methods used consist of spectrofluorimetry, ultraviolet (UV) spectroscopy, thin layer chromatography (TLC), and high-performance liquid chromatography (HPLC). These methods were used to determine the amount of duloxetine in bulk drugs, pharmaceutical dosage forms and biological matrix. HPLC with ...

The development of high-performance liquid chromatography (HPLC) in the years of 1965 to 1985 was undeniably a success story. However, an important limitation of the technique remained: in comparison to capillary gas chromatography the resolving power accessible in a reasonable analysis time is poor. The introduction of a range of miniaturized liquid phase techniques, exploiting either pressure...

HPLC, column and thin layer chromatography guided studies led to the isolation of seven different compounds in methanolic extracts of Podophyllum hexandrum. The isolated compounds were analyzed using LC-MS and High Performance Liquid Chromatography (HPLC) studies interfaced to mass spectroscopy. Isolated compounds were used successfully as chemical markers for the comparison of the twelve diffe...

in the present study, a comprehensive and systematic strategy was described to evaluate the performance of several three-way calibration methods on a bio-analytical problem. parallel factor analysis (parafac), alternating trilinear decomposition (atld), self-weighted alternating trilinear decomposition (swatld), alternating penalty trilinear decomposition (aptld) and unfolded partial least squa...

background: cattle can be considered as an important source for herbicides through nutrition. therefore, herbicide residue in animal products is a potential human exposure to herbicides causing public health problems in human life. triazines are a group of herbicides primarily used to control broadleaf weeds in corn and other feed ingredients and are considered as possible human carcinogens. to...
