Determination of Malathion and α-Endosulfan Residue in Khazar Rice Using Matrix Solid Phase Dispersion and HPLC
An extraction method based on matrix solid phase dispersion (MSPD) and high performance liquid chromatography with UV detection for quantification of two widely used pesticides (Malathion and α-Endosulfan) in Khazar rice from north of Iran were investigated. The ratio of solid phase (adsorbent) to sample, types of eluting solvent and its volume were optimized to achieve the highest recoveries f...
متن کاملMatrix Solid Phase Dispersion and Online Coupling for the Analysis of Environmental Samples
This licentiate thesis is based on two papers that describe two original methods for analysing environmental pollutants. In both cases samples were extracted by onor off-line Matrix Solid Phase Dispersion (MSPD), then target analytes were separated from potentially interfering matrix components and analysed by Liquid Chromatography–Mass Spectrometry (LC-MS). Hot water and a small volume of meth...
متن کاملMatrix solid phase dispersion (MSPD).
A review of the many uses of matrix solid phase dispersion (MSPD) in the extraction and analysis of a variety of compounds from a range of samples is provided. Matrix solid phase dispersion (MSPD) has found particular application as a somewhat generic analytical process for the preparation, extraction and fractionation of solid, semi-solid and/or highly viscous biological samples. Its simplicit...
متن کاملUltrasonic-Assisted Matrix Solid-Phase Dispersion and High-Performance Liquid Chromatography as an Improved Methodology for Determination of Oleuropein from Olive Leaves
In this study, ultrasonic-assisted matrix solid-phase dispersion (UA-MSPD) as a new sample preparation method for natural product analysis was developed. Influential parameters of the UA-MSPD method was optimized using oleuropein content of olive leaves as a model analyte. Main parameters of the proposed technique such as ultrasonic time, amplitude and pulse, sorbent material, the ratio of samp...
متن کامل[Determination of benzo[a]pyrene in vegetable oils by HPLC coupled with matrix solid phase dispersion].
Determination of benzo(a)pyrene in vegetable oils was carried out using aluminium oxide for clean-up followed by reverse phase high performance liquid chromatographic (HPLC). A quantity of oil was dissolved in petroleum ether and added to an aluminium oxide column which retained the lipids. Benzo(a)pyrene in the oil was eluted from the column with petroleum ether and the collected eluate was co...
