Chemical characterization studies for medical devices rely on extract preparation techniques such as liquid–liquid extraction to render the more amenable instrumental analysis. Considering these are generally non-targeted, effect of full range potential analytes must be considered. However, there is currently no workflow evaluating impact non-targeted extractables. Herein, we present a framewor...
a user-friendly and inexpensive ionic liquid-based single-drop microextraction (il-sdme) method was developed to preconcentrate trace amounts of aminophenol isomers (aps) from human urine, hair dye and water samples prior to analysis by high performance liquid chromatography-ultraviolet spectrophotometry detection (hplc-uv). under optimum conditions (i.e., 3.5 µl of 1-hexyl-3-methylimidazolium ...
a validated hplc method was developed to determine doxorubicin concentration in a small volume of rat plasma (60 µl) with convenient fluorescence detection. sample preparation includes a simple one-step liquid-liquid extraction using minimum amount of organic solvent, with extraction recoveries more than 95%. the analysis was accomplished using perfectsil c18 column maintained at 35 °c and a mo...
Background:Extraction of drugs is one of the biggest concerns and the most important part of preparation and determination in forensic medicine. The lack of an easy, efficient and fast extraction method is the most important and most difficult problem despite the development of forensic centers and their being equipped with new diagnostic devices. In the present study, a comparison was conducte...
abstract polycyclic aromatic hydrocarbons (pahs) are classified as persistent and carcinogenic organic pollutants. pahs contamination has been reported in water. many of relevant regulatory bodies such as eu and epa have regulated the limit levels for pahs in drinking water. in this study, 13 priority polycyclic aromatic hydrocarbons (pahs) were determined in tap water samples of tehran and wat...
