Solid-Phase Extraction (SPE): Principles and Applications in Food Samples.
Solid-Phase Extraction (SPE) is a sample preparation method that is practised on numerous application fields due to its many advantages compared to other traditional methods. SPE was invented as an alternative to liquid/liquid extraction and eliminated multiple disadvantages, such as usage of large amount of solvent, extended operation time/procedure steps, potential sources of error, and high ...
متن کاملPlate-to-plate fluorous solid-phase extraction for solution-phase parallel synthesis.
A commercially available Argonaut VacMaster-96 plate-to-plate solid-phase extraction (SPE) station equipped with 24 FluoroFlash cartridges is employed for parallel purification of fluorous reaction mixtures. Each cartridge charged with 3 g of fluorous silica gel has the capability to produce up to 100 mg of purified small molecules. The 24-well receiving plate has a standard footprint that can ...
متن کاملRecycling of a perfluoroalkylated BINOL ligand using fluorous solid-phase extraction{
The fluorous biphase system has been applied successfully to a wide range of homogeneous catalyses with excellent catalyst recovery and reuse being reported. However, it is unlikely to be exploited commercially because of intersolvent leaching problems, the prohibitive expense of the perfluorocarbon solvents and concerns about their environmental persistence. An alternative approach, designed b...
متن کاملOne-step solid-phase extraction procedure for F(2)-isoprostanes.
brovascular occlusive disease, or from peripheral arterial occlusive disease. As shown in Table 1, there were distinctly higher homocysteine concentrations for seropositive subjects in subgroups of age, renal function, smoking status, and MTHFR gene mutations. These variables influencing serum homocysteine, as well as vitamin B 6 , vitamin B 12 , and folic acid, are moreover homogeneously (not ...
متن کاملRemoval of Triton X-100 from Plasma Samples Using Mixed-Mode Solid Phase Extraction (SPE)
in t ro du C t io n Pharmaceutical dosing vehicle excipients such as Triton X-100 are often added to formulations to facilitate dissolution in dosing media. Unfortunately, these compounds can cause significant matrix effects, typically ion suppression, in LC/MS/MS analyses. The use of fast LC gradients, common in drug discovery, can result in co-elution of target analytes with these compounds. ...
